SECTION 1 GENERAL INFORMATION

GENERAL INFORMATION

1.1 SCOPE OF MANUAL

This service manual contains operating, programming, alignment, and service information for the E.F. Johnson 7780 800 MHz portable transceiver.

1.2 EQUIPMENT DESCRIPTION

1.2.1 INTRODUCTION

The 7780 800 MHz portable transceiver is available in limited keypad (3-key) and full keypad (15key) models. In addition, standard and intrinsically safe versions are available (see Section 1.2.3). With all versions, up to 16 zones can be programmed, and each zone can contain up to 16 channels resulting in up to 256 total channels. The rotary switch on the top panel provides channel select, and an option switch provides zone select if applicable.

The 7780 is an 800 MHz transceiver which operates on the 920 channels from 806-824 MHz (mobile transmit). The receive channels are 45 MHz above these frequencies from 851-869 MHz. All models can be programmed for both narrow and wide band operation. With narrow band operation, the channel spacing is 12.5 kHz and maximum deviation 2.5 kHz; with wideband operation, the channel spacing is 25 kHz and maximum deviation is 5 kHz. On NPSPAC channels, maximum deviation is 4 kHz (see Section 1.2.5).

models is also used to service these models. Refer to Section 1.10 for more information on the intrinsically safe rating and additional requirements for servicing intrinsically safe models.

1.2.4 SYSTEMS, CHANNELS, AND ZONE S

A zone and channel are selected to place and receive calls. The following describes the relationship between systems, channels, and zones.

Systems

A system as used with this transceiver is a collection of channels (talk groups) belonging to the same repeater site. A system defines all the parameters and protocol definitions required to access a site. Up to 1 conventional system and 15 SmartNet/SmartZone systems can be programmed (16 total). Systems are used for programming purposes only and are not selectable by the user.

Channels

A channel selects a radio channel or talk group in a system as follows:

Conventional Mode - A channel selects a specific radio channel, Call Guard (CTCSS/DCS) squelch coding, and other parameters unique to that channel.

1.2.2 OPERATING PROTOCOLS

The 7780 operates on analog channels utilizing

the following operating protocols:

• Conventional (non trunked)

• SMARTNET II/SmartZone (trunked)

1.2.3 INTRINSICALLY SAFE MODELS

NOTE: Contact your sales representative to determine the availability of intrinsically safe models.

The intrinsically safe versions of the 7780 (see Section 1.3) meet Factory Mutual standards for operation in certain flammable atmospheres. Basically , the same service information used to service standard

SmartNet/SmartZone Mode - A channel selects a specific talk group, announcement group, emergency group, and other parameters unique to that channel.

As previously described, a maximum of up to 256 channels can be programmed with the preceding modes. The conventional system can be programmed with up to 256 channels, and each SmartNet/SmartZone system can be programmed with up to 256 talk groups (channels).

Therefore it is theoretically possible to program any combination of these systems that produces up to 256 total channels. However, the maximum number may be limited by the available memory. For example, since more memory is required to program a SmartNet system than a conventional system, the total number

• Do not make any modifications to the circuitry.

• When replacing a part, use only the exact replace-

ment part listed in the service manual parts list.

• Do not install any accessory that is not specifically

approved for use with intrinsically safe 7780 models.

1.10.2 DEFINITIONS

Intrinsically Safe - This is a fire rating given to these transceivers by the Factory Mutual Research Corpora-

1-4

GENERAL INFORMATION

tion.When electrical equipment is given thisrating, the equipment is considered incapable of releasing sufficient electrical and thermal energy under normal operation or specified fault conditions per the testing standard to cause ignition of a specific flammable or combustible atmosphere in its most easily ignited concentration. In other words, this transceiver should not cause a fire or explosion when used in certain flammable atmospheres.

Fault - A defect or electrical breakdown of any component, spacing, or insulation which alone or in combinationwith otherfaults mayadverselyaffect theelectrical orthermalcharacteristicsofthe intrinsicallysafe circuit (for example, a s horted transistor).

1.10.3 POSSIBLE IGNITION SOURCES

When a transceiver is checked by Factory Mutual, possible sources of ignition are checked. These sources may be electrical (spark) or thermal (heat). The following could be sources of spark ignition:

• Dischargeof a capacitive circuit by a fault such as a

short circuit.

• Interruption of an inductive circuit.

• Intermittent making or breaking of a resistive

circuit.

• Hot-wire fusing.

ignition of a particular atmosphere if two of the faults specified in the testing procedure occur. In other words, it must be able to withstand two simultaneous unrelated breakdowns without causing ignition. To receive a nonincendive rating, the transceiver needs to withstand only a single fault without causing ignition of a particular atmosphere.

1.10.5 CLASSIFICATION OF HAZARDOUS AREAS AND ATMOSPHERES

Introduction

This transceiver has been submitted for approval to operate in the following hazardous atmospheres and areas. Contact your sales representative or refer to the label on the back of the transceiver to determine the specificatmospheres and areas for which approval was obtained.

Intrinsically Safe - Class I, II, and III, Division 1, Groups C, D, E, F, and G.

Nonincendive - Class I, Division 2, Groups A, B, C, and D.

Temperature Code - T3C

The meanings of these Class, Division, and Group designations are as follows.

The following could be sources of thermal

ignition:

• Heating of a small-gauge wire or PC board trace.

• High surface temperature of components.

1.10.4 INTRINSICALLY SAFE AND NONINCENDIVE RATINGS

This transceiver is rated intrinsically safe for some types of hazards and nonincendive for other types of hazards. An intrinsically safe rating applies to operation in Division 1 areas, and a nonincendive rating applies to operation in Division 2 areas (see next section). The difference between these ratings is as follows:

The intrinsically safe rating is a higher rating because more severe conditions must be met. To be approved for this rating, the transceiver must not cause

Atmosphere Classification (Class/Group)

For the purposes of testing and approval, various atmospheric mixtures have been grouped on the basis of their hazardous characteristics. Equipment is approved for a class of material and also for the specific gas, vapor, or dust in that class. Class I m aterials include gases and vapors, and Class II materials include combustible dusts. The various classes and some specific groups of gases in each are shown in Table 1-2.

Area Classification (Division)

Areas are either Division 1, 2, or 3 as shown in Table 1-3. Since a Division 1 area is considered the most hazardous, a transceiver approved for a specific Division 1 area can also be used in the same Division 2 Class/Group.

Zone Select

A zone is a group of up to any 16 conventional and SMARTNET/SmartZone channels defined by programming (see Section 1.2.4). Up to 16 zones can be programmed for a total of 16 x 16 or 256 channels. One use of zones may be to select groups of channels programmed for operation in different geographical areas or radio systems. Zones are selected as follows:

1. Press the Zone option switch and the alias (name) of

the current zone is flashed in the display.

2. Use the number keys to enter the desired zone

number or scroll through the available zones using the and keys.

3. Once the desired zone is displayed, press the ENT

key or wait 4 seconds.

2.3.8 HOME ZONE

The radio can be programmed with a home zone. Then when power is turned on, the radio can be programmed so that either the home or last selected zone is automatically selected.

channel it can be programmed for times from 15 seconds up to 3 minutes, 45 seconds or disabled (not used). If the t ransmitter is keyed continuously for longer than the programmed time, the transmitter is disabled and an i nvalid condition tone sounds. Five seconds before time-out occurs, an alert tone sounds to indicate that time-out is approaching. The timer and tone are reset by releasing the PTT switch.

One use of this feature is to prevent a channel from being kept busy for an extended period by an accidentally keyed transmitter. It can also prevent possible transmitter damage caused by transmittingfor an excessively long period. Conventional channels can also be programmed with the Penalty and Conversation timers that are described in Sections 2.4.7 and

2.4.8.

2.3.10 TONE ENABLE/DISABLE

The supervisory tones (see Section 2.6) can be enabled and disabled by the Tones On-Off option switch if it is programmed. When tones are enabled by this switch, “TONE ON” is momentarily displayed and a tone sounds. Conversely, when tones are disabled, “TONE OFF” is displayed and no tone sounds. If the Tones On-Off option switch is not programmed, tones are fixed in the on or off mode by programming.

2.3.11 SCANNING

Introduction

disabled and vice versa. More information on these modes follows.

Standard Scanning

Standard scanning monitors only channels that are the same type as that currently selected. Therefore, if a conventional channel is selected, only conventional channels are scanned, and if a SMARTNET channel is selected, only SMARTNET channels are scanned. Standard scanning is turned on andoffbytheScanoptionswitchasfollows.Ifthis switch is not programmed, standard scanning is not available.

• To turn standard scanning on, press the Scan option

switch. Scanning is enabled when the “S”iconis indicated in the upper left corner of the display and SCAN x (conventional) or SCAN ON (SMARTNET/SmartZone) is briefly displayed. The “x” is the number of the conventionalscan list (1, 2, or 3) that is selected. Refer to Section 2.4.11 for more information.

• To turn scanning off, press the Scan option switch

again. The “S” icon is then no longer indicated and “SCAN OFF” is briefly displayed.

• If the zone or channel is changed while scanning is

selected, scanning continues on the same or a different scan list (see scan list information which follows).

Scanning cycles through a list of channels, called a “scan list”, checking each for messages. When a message is detected that your transceiver is programmed to receive, scanning stops and the message is received. Shortly after the message is complete, scanning resumes (unless it has been disabled).

There are two basic scan modes: Standard and Radio Wide. The Standard mode is unique to the type of channel selected (conventional or SMARTNET/ SmartZone), and the Radio Wide mode is the same regardless of the channel type selected. Only one of these scan modes can be enabled at a time. Therefore, if standard scanning is enabled while radio wide scanning is occurring, radio wide scanning is automatically

November 1999 Part No. 001-7780-500

Radio Wide Scanning

Radio wide scanning monitors the channels in the preprogrammed radio wide scan list (see information whichfollows).Thislistmaycontainupto16channels of any type (conventional or SMARTNET/SmartZone) assigned to any zone. Radio wide scanning is turned on and off by the Radio Wide Scan option switch as follows. If this switch is not programmed, radio wide scanning is not available.

• To turn radio wide scanning on, press the Radio

Wide Scan option switch. The icon is then displayedcontinuouslyand “RWS ON” is displayed briefly.

• To turn radio wide scanning off, press the Radio

Wide Scan option switch again. The icon is then no longer indicated and “RWS OFF” is displayed briefly.

• If the zone or channel is changed while radio wide

scanning, radio wide scanning continues normally.

Scan Resume Delay

When a message is received or transmitted while scanning, there is a programmable delay before scanning resumes. The delay after receiving a call prevents another message from being received before a response can be made, and the delay after transmitting a call ensures that a response is heard to your call instead of another message occurring on some other channel.

Standard Mode Scan List

Determining Which Channels are in Scan List

Channels in the radio wide and standard SMARTNET/SmartZone scan lists are not indicated. With standard conventional scanning, the selected channel is in the current scan list if the box icon (around “S”) is indicated in the upper left corner of the display.

Nuisance Channel Delete

With standard scanning, both conventional and SMARTNET/SmartZone channels can be temporarily deleted from the scan list. This feature is not available with radio wide scanning. Proceed as follows:

NOTE: The selected channel and conventionalpriority channels cannot be deleted from the scan list.

1. While receiving a message on the channel to be

deleted, press and hold the Scan option switch until the alert tone sounds (about 1 second).

NOTE: The selected channel is always scanned.

With conventional operation when using the full keypad (15-key) model, up to three scan lists can be programmed. The list that is scanned is selected by the Scan option switch as described in Section 2.4.11. Selecting another conventional channel does not change the current scan list. In addition, the scan lists are user programmable if the Scan Edit option switch is programmed. With limited keypad (3-key) models, only Scan List 1 can be scanned, and it is not user programmable.

With SMARTNET/SmartZone operation, each channel can be programmed so that one of up to three different scan lists is automatically selected. Channels can also be programmed so that scanning is automatically disabled when they are selected. SMARTNET/ SmartZone scan lists are not user selectable or programmable.

Radio Wide Mode Scan List

With radio wide scanning, there is only one preprogrammed scan list available regardless of the type of channel selected, and it is not user programmable.

2. The channel is then deleted and scanning of the remaining channels in the scan list resumes.

3. Deleted channels are added back into the scan list if either of the following occur:

• Scanningis turnedoff a nd then on againusing the

Scan switch.

• Transceiver power is turned offand then on again.

2.3.12 CONVENTIONAL AND SMARTNET/

SMARTZONE O PERATION

Introduction

Each selectable channel is programmable for either conventional, SMARTNET, or SmartZone operation. For example, Zone 1/Channel 1 could be a conventional channel, Zone 1/Channel 2 a SMARTNET channel, and so on. More information on these modes follows.

Conventional Operation

This is a non-trunked operating mode which accesses independent radio channels (there is no a utomatic access to several channels as with trunked oper-

2-7

TRANSCEIVER OPERATION

ation). Monitoring before transmitting may not occur automaticallyin this mode, so the channel may have to be manually monitored before transmitting (see Section 2.4.3). Selecting a conventional channel selects a transmit and receive frequency and other parameters such as Call Guard squelch coding.

SMARTNET/SmartZone Operation

This is a trunked operating mode that uses ID codes to select which mobiles are being called and which calls are received. Monitoring is performed automatically and special messages and tones indicate busy and out-of-range conditions. Enhanced features include roaming (SmartZone only), telephone, private, and emergency calls, Call Alert, and messaging. Operating features unique to SMARTNET/SmartZone channels are described in Section 2.5.

This radio supports only the SMARTNET II trunking protocol. It does not support the SMARTNET I (also referred to as Type I) protocol. W hen a SMARTNET or SmartZone channel is selected or the radio is powered up on a SMARTNET/SmartZone channel, it searches for a control channel and attempts to register on the radio system. Once a control channel is found, the alias (name) of the selected channel is displayed. If a control channel could not be found (because of an out of range condition or the system ID is not correct, for example), “NO SYS” is displayed and the radio continues to search for a control channel.

The control channel transmits and receives system information to and from all radios registered on the system. Therefore, once a control c hannel is found, it is continuously monitored for incoming call information and is used to make call requests. The radio automatically changes to a traffic channel to place and receive calls and then returns to the control channel when the call is complete.

2.4 CONVENTIONAL FEATURES

2.4.1 INTRODUCTION

2.4.2 DISPLAY MODE SELECTION

If the Displayed Information option switch is programmed, the display mode used to indicate conventional channels can be user selected. Pressing this switch cycles between the following modes. The selected mode does not change when power is turned off. If the Displayed Information option switch is not programmed, the Alias mode is always used.

Alias - The preprogrammed alphanumeric tag for the channel is displayed.

Number - The channel number from 1-16 is displayed.

Frequency - The receive frequency of the selected channel is displayed in megahertz.

2.4.3 MONITORING BEFORE TRANSMITTING

With conventional operation, channels are monitored automatically or manually as follows:

Automatic Channel Monitoring

If the selected channel is programmed for the Busy Channel Lockout feature, monitoring is performed automatically. Refer to the description of this feature in Section 2.4.5 for more information.

Manual Channel Monitoring

The automatic monitoring just described may not be programmed or it may occasionally disable the transmitter even i f the channel is not in use. In this case, the channel must be monitored manually as follows:

Rx Indicator

- With scanning disabled, note if the greenRX indicator on the top panel is on. If it is not, the channel is not being used and the call can be transmitted. If it is on, a carrier is being detected, so the channel may be busy (see next paragraph).

The following information describes features unique to the conventional operating mode (described briefly in Section 2.1.2). Refer to Section 2.3 for information on features common to all operating modes, andtoSection2.5forinformationonfeaturesunique to the SMARTNET/SmartZone mode.

November 1999 Part No. 001-7780-500

2-8

Monitor Mode

- There may be times when the busy indication is displayed even though no one is using the channel. Monitoring should then be performed by disabling Call Guard squelch using the Normal/ Selective option switch as described in Section

2.4.6 or the monitor mode described next.

TRANSCEIVER OPERATION

2.4.4 MONITOR MODE

The monitor mode temporarily disables squelch control features (such as Call Guard squelch) so that all messages are heard on the selected channel. It also overrides the Busy Channel Lockout feature (see next section) and temporarily halts scanning.

To monitor the selected transmit channel, select the monitor mode by briefly pressing the Monitor option switch (if available). The icon is displayed and the receiver unsquelches (even if no carrier is detected). To disable the monitor mode and return to normal operation, press the Monitor switch a second time.

To monitor the selected receive channel instead of the transmit channel, press and hold the Monitor switch until the alert tone sounds (approximately 1 second). This function may be useful, for example, during weak signal conditions if intermittent squelching makes a message difficult to understand.

2.4.6 CALL GUARD SQUELCH

General

Call Guard® squelch (also called CTCSS/DCS signaling) can be programmed on conventional channels. This feature eliminates distracting messages intended for others using the channel by using a subaudible tone or digital code to control the squelch. This tone or code is unique to a user or talk group on that channel. It is transmitted by the mobile placing a call, and if Call Guard squelch is programmed in the mobile receiving the call, it must detect the correct tone or code to receive the call.

Call Guard Squelch Enable/Disable

To disable Call Guard (Selective) squelch so that all messages on the selected or scanned channels are heard, press the Normal/Selective option switch if programmed. The receiver unsquelches only if a carrier is detected. To re-enable Call Guard squelch, press the Normal/Selective switch again.

2.4.5 BUSY CHANNEL LOCKOUT

The Busy Channel Lockout feature (also called Transmit Disable On Busy) automatically disables the transmitter if the channel is busy when the PTT switch is pressed. When a busy condition is detected by this feature, the transmitter is disabled, “BUSY” is indicated in the lower part of the display, and a tone similar to a standard telephone busy tone sounds until the PTT switch is released. This feature is programmed to operate in one of the following modes on each channel:

Off - The transmitter keys even if the channel is busy. Noise - The transmitter is disabled if any signal is

detected on the channel.

Tone - The transmitter is disabled if the detected

squelch coding is not correct.

If busy override is permitted by programming, it is possible to transmit even when the transmitter i s disabled by this feature. Simply quickly release the PTT switch and press it again.

When Call Guard squelch is disabled by this switch, “SQ NORM” is flashed on the lower line of the display, and when it is enabled, “SQ SLCT” is flashed. The selected mode does not change when other channels are selected or power is cycled. Call Guard squelch can also be disabled by the monitor mode described in Section 2.4.4.

Changing the Call Guard Code

If using the full keypad (15-key) model and the ability to change Call Guard codes has been enabled by programming, the transmit and receive codes from one channel can be temporarily or permanently reassigned to all channels of the current zone. Proceed as follows:

1. Using the number keys, enter the number of the

channel that is programmed with the code you want to reassignto all channels (only channels1-9 can be selected). See Section 2.4.2 for information on how to display channel numbers.

2. The display thenbriefly indicates“CODE x”, where

“x” is the key that was pressed. The codes assigned

2-9

TRANSCEIVER OPERATION

to that channel are then reassigned to all the other channels in the current zone. The reassignments remain in effect even after power is cycled.

3. To restore all Call Guard codes in the current zone totheoriginalsettings,pressthe“0”key.

2.4.7 PENALTY TIMER

A penalty timer m ay be programmed on conventional channels to prevent transmissions for a period of time after the time-out timer described in Section 2.3.9 disables the transmitter. The penalty timer starts when the PTT switch is released after the transmitter has been disabled. If the PTT switch is pressed during the penalty time, the time-out indication occurs again. A beep sounds when the penalty timer expires and the transmitter can then be keyed.

2.4.8 CONVERSATION TIMER

A conversation timer can be programmed on conventional channels to limit the total length of a conversation rather than just the length of each transmission as with the time-out timer. This timer is reset when the time between transmissions exceeds the penalty time just described. A warning tone sounds 5 seconds before the conversation timer expires. When it expires, the transmitter is disabled and a warning tone sounds. The transmitter remains disabled for the length of the penalty time, and a beep sounds when it can be keyed again.

2.4.9 REPEATER TALK-AROUND

Normally, all transmissions go through a repeater which usually increases range. However, if out of range of the repeater,you cannot talk to anyone else on that channel even though the mobile you are calling may be only a short distance away. To allow communication when this situation occurs, repeater talk-around can be used to transmit on the receive frequency. This allows direct communication with a mobile without going through a repeater.

Repeater talk-around can be selected if the Repeater Talk-Around option switch is programmed. When talk-around is enabled by this switch, the icon is displayed and “RTA ON” is flashed in the display. Then when it is disabled by pressing this

switch again, that icon is no longer displayed and “RTA OFF” is flashed. Changing channels or turning power off does not change the selected talk-around mode.

2.4.10 POWER OUTPUT SELECT

If the High/Low Power option switch is programmed and power selection is permitted on the current channel by programming, either high or low transmitter power can be selected. Generally, the high power setting transmits longer distances but uses more battery power, and the opposite occurs with the low power setting. When the low power is selected on the current channel, “LOW” is indicated continuously near the bottom of the display.

Pressing the High/Low Power switch toggles the power setting. The new level is flashed in the display when this switch is pressed as “HI POWER” or “LO POWER”. If power selection is not permitted on the channel, the fixed power level is flashed and no power change occurs. Turning power off or changing channels does not change the power setting selected for a channel.

2.4.11 CONVENTIONAL MODE SCANNING

General

The following information describes scanning features unique to conventional operation. Scan operation common to all modes is described in Section

2.3.11, and scan operation unique to SMARTNET/ SmartZone operation is described in Section 2.5.12.

Selecting a Scan List

When standard scanning with full keypad (15key) models, one of up to three scan lists can be selected. These lists can be user programmed as described in the information which follows. With limited keypad (3-key) models, only one scan list is available and is not user programmable. However, nuisance channels can still be temporarily deleted as described in Section 2.3.11.

Proceed as follows to select a scan list with full keypad models:

November 1999 Part No. 001-7780-500

2-10

TRANSCEIVER OPERATION

1. Press the Scan option switch to enable scanning. The currently selected scan list is momentarily indicated as “Scan x”, where “x” is the list number (1-3).

2. To selectone of the other lists,press the number key corresponding to the desired list (1-3) and the selectedlist is then momentarily displayedas “Scan x”. The selected scan list is stored in memory and does not change until this procedure is repeated.

Programming a Scan List

With full keypad (15-key) models, each of the three scan lists is user programmable if the Scan Edit option switch is programmed and user programming of the list is allowed. Otherwise, the channels in these lists are determined by dealer programming. User scan list programming is not available with limited keypad (3-key) models. Proceed as follows to program a scan list:

1. Make sure all scanning is off (neither the standard

scan “S” icon or radio-wide scan icon is displayed).

Transmitting in Scan Mode

Each conventional scan list can be programmed for one of the following modes. These modes determine if priority sampling occurs and also the channel on which transmissions occur while scanning. Refer to the next section for more information.

No Priority - No priority channel sampling occurs when the list is selected. The radio transmits on the selected channel.

Priority/Tx Priority - Priority sampling occurs and the priority channel is the one programmed in the selected scan list. The radio transmits on the priority channel.

Priority/Tx Selected - Priority sampling occurs and the priority channel is the one programmed in the selected scan list. The radio transmits on the selected channel.

Priority on Selected - The priority channel is always the selected channel. The radio transmits on the selected channel.

2. Press the Scan Edit option switch and then within 2 seconds press the number key corresponding to the scan list you w ant to edit (1-3). If a list is not selected within the allotted time, the last active conventional standard scan list is automatically selected.The selectedlist is indicatedas “SCAN x”. If user programming is disabled on a list, “NO LIST” is momentarily displayed and it cannot be edited.

3. Select the channel you want to add or delete using the and keys. To change zones, press the F1 key and select the new zone.

4. If the selected channel is in the scan list, the box

around “S” is i ndicated in the upper left corner of the display. To add the channel to the scan list, pressthe“1” key,and todelete thechannel, press the “2” key.

NOTE: The priority channel cannot be deleted (see Section 2.4.12).

5. To exit this mode and save the changes, press the ENT or CLR key.

Talkback - No priority sampling occurs. The radio transmits on the channel of a call while scanning is halted. Then once scanning resumes, it transmits on the selected channel.

2.4.12 PRIORITY CHANNEL SAMPLING

General

The priority channel sampling feature ensures that when standard scanning, messages on the priority channel are not m issed while listening to a message on some other channel. The transceiver can be programmed so that the priority channel is a fixed channel associated with the current scan list, the currently selected channel, or not used (see preceding section). When the selected channel is a priority channel,

“P”

is indicated in t he upper right part of the

display.

Priority channel sampling occurs only with Standard conventional scanning. It does not occur with Radio Wide scanning, when listening to any type of SMARTNET/SmartZone call, or when transmitting. A series of “ticks” may be heard when the priority

2-11

November 1999

Part No. 001-7780-500

TRANSCEIVER OPERATION

channel is sampled while listening to a message on some other channel.

The priority sampling times are programmed by

the following parameters:

Lookback Time A - This time determines how often the priority channel is checked for activity. Times of

0.25-4.00 seconds in 0.25-second steps can be programmed.

Lookback Time B - This time determines how often the priority channel is checked once an incorrect Call Guard (CTCSS/DCS) code is detected. Since it takes much longer to detect an incorrect Call Guard signal than a carrier, this time should be relatively long to prevent the interruptions from making a message difficult to understand. Times of 0.5-8.0 seconds can be programmedin0.5-secondsteps.

Changing The Priority Channel

If a specific priority channel is associated with the current scan list, it can be changed if the Priority option switch is programmed. Proceed as follows:

Placing a Standard Conventional Call

1. Turn power on and set the volume as described in Section 2.3.2. Select the channel programmed for the mobile you want to call (see Section 2.3.7).

2. Monitor the channel automatically or manually as described in Section 2.4.3.

3. Press the PTT switch and the call proceeds as follows:

• If the Busy Channel Lockout feature is

programmed on the channel, the transmitter is automaticallydisabled if the channel is busy (see Section 2.4.5).

• Otherwise, busy and out-of-range conditions are

not indicated and speaking can begin after monitoring the channel.

4. Press (and hold) the PTT switch to talk and release it to listen.

Receiving a Standard Conventional Call

1. Make sure all scanning is off (neither the standard scan “S” icon nor radio-wide scan icon displayed).

2. Select the channel that you want to be the priority channelusing the channel selector switch on the top panel.Ifthe channelis ina differentzone,also select the appropriate zone.

3. Press the Priority option switch and the “P”iconis displayed to indicate that the selected channel is now the priority channel.

2.4.13 STANDARD CONVENTIONAL CALLS

Standard conventional calls are calls to or from other mobile units on the selected channel. The proper coded Call Guard signaling (see Section 2.4.6) may need to be transmitted for them to receive your call and also for you to receive their calls. Proceed as follows to place and receive these calls:

1. Select or scan the channel programmed for the call you want to receive (refer to Sections 2.3.11 and

2.4.11 for more scanning information).

2. When the call is r eceived, press the PTT switch to talk and release it to listen. If scanning, you may have to respond before scanning resumes to ensure that the response occurs on the channel of the call.

2.4.14 DTMF/ANI SIGNALING

DTMF (Dual Tone Multi-Frequency) tones can be generated manually or automatically for ANI (Automatic Number Identification) and other purposes. The following options may be enabled by dealer programming for each conventional channel:

DTMF Keypad - With full keypad (15-key) models only, pressing 0-9, , or # on the keypad while holding the PTT switch transmits the corresponding tone until the key is released.

Pre-Tx ANI - A preprogrammed ANI sequence is automatically sent when you press the PTT switch.

2.5.10 EMERGENCY ALARM AND CALL

Introduction

Emergency Alarms and Calls are separate functions that can be individually enabled or disabled on eachSMARTNET/SmartZonesystem. The Emergency option switch is also required for these functions, and it is always the lower button (FCN) on the side when it is used. Emergency Alarms and Calls are transmitted on the emergency talk group programmed on the selected system.

Emergency Alarms

An emergency alarm is a special data transmission that alerts a dispatcher of an emergency situation. Proceed as follows to activate an emergency alarm:

1. Select a SMARTNET/SmartZone channel that has

this feature enabled and then press the Emergency option switch. The radio then begins automatically transmitting an emergency alarm data message and “EMERGNCY” is indicated in the display for 3 seconds.

2.5.9 SENDING STATUS CONDITIONS

The status feature allows the current status to be sent to a dispatcher. Up to eight status conditions can be preprogrammed, and they are identified by an alias (name). If the Status option switch is programmed, status conditions are sent as follows:

1. Momentarily press the Status option switch. The

alias of the last status sent is displayed.

November 1999 Part No. 001-7780-500

2. When the emergency alarm is acknowledged, the emergency acknowledge tone (two beeps) sounds. Silent operation may also be programmed in which case no tone sounds and there is no indication that an acknowledgment occurred.

3. Theradio continuestotransmit this messageuntil an acknowledgment is received or the programmed number of attempts have been made. To exit this mode, power must be turned off and then on again.

TRANSCEIVER OPERATION

Emergency Calls

An emergency call urgently requests access to a

voice channel. To place this call, proceed as follows:

1. Select a SMARTNET/SmartZone channel that has thisfeature enabledand pressthe Emergencyoption switch. The emergency mode is indicated when “EMERGNCY” is indicated in the display for 3 seconds.

2. To place the emergency call, manually press the PTT switch and begin s peaking as with a standard call. All group calls which follow are then emergency calls (private, telephone, and call alert calls are not allowed). If the channel is changed, the call is made on the emergency talk group programmed for the new channel.

3. Toexit this mode, power must be turned off andthen on again.

ning disabled. Then when a channel is selected again that permits scanning, it is automatically re-enabled.

In addition to calls on channels in the scan list, pages, private calls, and telephone calls are received while scanning. Messages on the priority channel are received while listening to lower priority messages. However, private and telephone calls are not interrupted by calls on the priority channel.

2.5.13 DYNAMIC REGROUPING

The dynamic regrouping feature allows a dispatcher to switch users to a dynamically defined channel to receive an important message. Dynamic regrouping operates as follows:

1. When this command is received, the alternating

dynamic regrouping tone sounds, the transceiver automatically changes to the regrouping channel, and the display alternately indicates “REGROUP” and the alias of the selected channel. All transmitting and receiving then occurs on this channel.

If a failure occurs in the SMARTNET/SmartZone system so that it cannot be used, the transceiver automatically enters the failsoft mode. When this mode is selected, the display alternately indicates “FAILSOFT” and the alias of the selected channel.

When in the failsoft mode, operation is in the conventional mode on a preprogrammed failsoft channel. If a transmission is attempted before a failsoft channel is located, a continuous tone sounds until the PTT switch is released. When the radio system returns to normal operation, this condition is automatically detected and normal operation resumes.

2.5.12 SMARTNET/SMARTZONE SCANNING

Scanning on a SMARTNET/Smartzone channel is similar to the standard scanning described in Section

2.3.11.Eachchannelcanbeprogrammedwitha different scan list that includes up to 16 channels, one of which can be a priority channel.

Scanning is enabled/disabled by the Scan option switch. In addition, channels can be programmed so that scanning automatically starts whenever the channel is selected. Scanning is temporarily disabled and “S” turns off if a channel is selected that has scan-

2. To reset all talkand announcementgroups to normal so thatonly the designated regrouping channel is on the dynamic group, manually select t he designated regrouping channel if you know it. If this channel is not selected or there is no designated regrouping channel,all transmissions occur on the dynamically assigned group regardless of which channel is selected, and the regrouping tone sounds each time the PTT switch is pressed.

3. When regrouping is canceled by the dispatcher, transceiver operation returns to normal.

2.5.14 SMARTZONE FEATURES

Introduction

As described in Section 2.3.12, the SmartZone® mode provides wide area coverage by allowing roaming between SMARTNET and conventional sites. SmartZone operation is the same as SMARTNET with the following additional features:

Determining Current Site

To determine the current radio site, momentarily press the Site Search option switch (if programmed). If

currently registered on a site, “SITE x” is displayed, where“x”isthesitenumber.Ifthesiteislocked(see following), “LOCK x” is displayed instead. The display then indicates the RSSI (Receive Signal Strength Indicator) value of the current s ite as “RSSI x” and then returns to displaying the channel alias.

Searching For a New Site

To display the RSSI level of the current site, press the Site Search option switch (if programmed). The current site number is then displayed as “SITE x” followed by the RSSI level as “RSSI x”. If the Site Search option switch is not pressed again, this mode is automatically exited and the normal channel information again displayed.

To scroll through the other programmed sites, repeatedly press the Site Search option switch while “SITE x” or “RSSI x” is displayed. Each time it is pressed, the information for the next site is displayed. To select the displayed site, simply do not press the switch again and that site is selected when the normal channel display returns. If site lock is on when site search is entered (see following), the radio will be locked on the new site when this function is exited.

Locking/Unlocking a Site

It is sometimes desirable to stay on the current site regardless of signal level. To lock the radio on the current site so that it does not search for another, press the Site Lock option switch (if programmed). The display then momentarily indicates “LOCK x” to indicate that the current site is locked (“x” is the current site number). To unlock the site, press the Lock switch again and “UNLOCK” is momentarily displayed.

When locked on a site, it is still possible to search for a different site using the site search function described in the preceding section. When a new site is found, the radio is then locked on that site.

CIRCUIT DESCRIPTION

the VCO from the receiver and transmitter and the counters in synthesizer IC1.

A switching circuit on the output of Q10 routes the VCO signal to the receiver in the receive mode and the transmitter in the transmit mode. In the receive mode, the R5V receive supply is applied to R12 and current flows through R12, D7A, and R51. Since D7A is forward biased, it presents a low impedance path to first mixer Q2 in the receiver. D7C is then reverse biased, so there is a high impedance path to the transmitter.

The5VreceivesupplyisalsoappliedtoR78and current f lows through R78, D7B, and R79. This results in less reverse bias and therefore charge on D7C to permit faster switching. In the transmit mode, the 5V receive supply is no longer present, so both D7A and D7B are reverse biased. D7C is forward biased by the current path through R50 and R51.

4.2.3 VCO AND TCXO MODULATION

Both the VCO and TCXO are modulated in order to achieve the required frequency response. If only the VCO was modulated, the phase detector in IC1 would sense the frequency change and increase or decrease the VCO control voltage to counteract the change (especially at the lower audio frequencies). Conversely, if only the TCXO was modulated, the VCO frequency would not change fast enough (especially at the higher audio frequencies).

However, by modulating both the VC O and TCXO, the two phase detector inputs remain in phase and no frequency shift is sensed. This produces a relatively flat audio response. Potentiometer B4 in IC209 is used to balance these signals and potentiometers B1 andB3areusedtosetthedataandaudiodeviation level. IC4 is an amplifier, and R73 sets the frequency of the TCXO by adjusting the DC bias of IC4.

4.2.4 SYNTHESIZER CHIP (IC1)

Synthesizer chip IC1 contains a prescaler, A, N, and reference counters, and a phase detector. Channels are selected by programming the A, N, and reference counters to divide by a certain number. This programming is performed by the microprocessor via the serial data bus which consists of lines PLLSK, PLLSO, and PLLST (pins 9-11 of IC1).

The divide numbers are chosen so that when the VCO is operating at the correct frequency, the VCOderived input to the phase detector is the same frequency as the TCXO-derived input. The TCXOderived input is produced by the reference counter in IC1. This counter divides the 14.925 MHz TCXO frequency by 2388 to produce a 6.25 kHz input to the phase detector. Using a 6.25 kHz reference frequency allows channels to be changed in 6.25 kHz steps.

The VCO-derived input is produced by dividing the VCO frequency using the prescaler and N counter in IC1. The divide number of the prescaler is controlled by the output signal from the A counter. The A and N counters function as follows:

Both the A and N counters begin counting down from the programmed number. When the A counter reaches zero, it halts until the N counter reaches zero. Both counters then reset and the cycle repeats. The A counter is always programmed with a smaller number than the N counter. When the A counter is counting down, the control output to the prescaler causes the prescaler to divide by 129. Then when the A counter is halted, the control output changes states and the prescaler divides by 128.

4.2.5 LOCK DETECT (Q13)

When the synthesizer is locked on frequency, the LD (Lock Detect) output of IC1 (pin 7) is a high signal. This turns lock detect transistor Q13 off and the ULOCK signal fed to the microprocessor is low. When an unlocked condition is indicated, low-going pulses appear on pin 7. Q13 then turns on and the ULOCK signal goes high. The transceiver is then disabled by the logic and an error condition is indicated in the display.

4.2.6 CHARGE PUMP (Q1, Q2), LOOP FILTER

The charge pump circuit consisting of Q1 and Q2 charges and discharges C4 and C5 in the loop filter to produce the VCO control voltage. Supply voltage to Q1 is provided by CPV regulator IC2 on the IF board.

Pulses which control the charge pump are output by synthesizer IC1 on pins 15 and 16. When the VCO is on the correct frequency, both phase detector outputs are in phase. Pin 15 is then high and pin 16 is low which turns both Q1 and Q2 off. Then if the VCO

CIRCUIT DESCRIPTION

frequency is low, the VCO-derived input to the phase detector is lower than the TCXO-derived input (or the phase lags the TCXO-derived input). Pin 15 of IC1 then pulses low and turns Q1 on. This charges the loop filter capacitors which increases the VCO control voltage. The VCO frequency then increases until the phase detector inputs are again the same frequency and phase. If the VCO frequency is too high, pin 16 pulses high which discharges the loop filter capacitors.

The loop filter is formed by R7-R9 and C4/C5. This is a low-pass filter which controls synthesizer stability and lock-up time and suppresses the 6.25 kHz reference frequency.

4.3 RECEIVER CIRCUIT DESCRIPTION

NOTE: A block diagram of the RF and logic units is located on page 8-3.

4.3.1 RF AMPLIFIER (Q1), FIRST MIXER (Q2)

The receive signal from the antenna is fed through low-pass filter FI7 and the antenna switch (see Section 4.4.2) to bandpass filter FI1. This filter attenuates the image and other unwanted frequencies and also prevents the injection signal from being fed out to the antenna.

The signal is then f ed to RF amplifier Q 1. Impedance matching with FI1 is provided by L32, C4, C138, and R104. The RF amplifier is used to recover filter losses and improve the sensitivity of the receiver. The output of Q1 is fed to FI2 which is a bandpass filter similar to FI1. Impedance matching is provided by L5 and C7.

From FI2 the signal is fed to gate 1 of first mixer Q2.Thisisadual-gateMOSFETdevicewhichmixes the receive frequency with the first injection frequency to produce a first IF of 45.225 MHz (low-side injection is used). The injection frequency is from the synthesizer, and it is fed through a low-pass filter consisting of C22-C24 and L12. This filter attenuates harmonic frequencies present in the injection signal. A 3-dB pad consisting of R9-R11 provides the required input level to the mixer, and L11 and C12 provide matching.

Impedance matching on the input of Q2 is provided by C11, L6-L8, and L33. Likewise, imped-

ance matching on the output is provided by C15, L9, L10, C18, C19, and R99. The first IF signal is then fed to four-pole crystal filter FI3. This filter attenuates wideband noise, adjacent channels, frequencies resulting from intermodulation, and other frequencies close to the receive channel.

4.3.2 IF AMPLIFIER (Q2), LIMITER/DETECTOR (IC3)

From crystal filter FI3, the IF signal is fed to IF amplifier Q2 on the IF board. This stage provides the required input level to the next stage. The signal is then fed to limiter/detector IC3. This device contains second mixer and oscillator, limiter, detector, squelch, and RSSI stages (see Figure 4-1).

The IF signal is fed in on pin 16 which is the input of an internal mixer.The 45.225 MHz first IF signal is mixed with the 44.775 MHz second injection signal to produce a second IF of 450 kHz. The 44.775 injection signal is produced by multiplying the TCXO frequency by three. This multiplication is performed by Q18 and other components.

The 450 kHz second IF is fed out of IC3 on pin 3 and applied to ceramic filters FI6, FI5, and FI4. These filters are used to attenuate wideband noise. A switching network consisting of D13-D16 routes the IF signal through all three filters with narrow band and NPSPAC operation, and through only FI4 with wideband operation. This switching network is controlled by WIDE and NAR signals from Q19-Q21. The W/N

CIRCUIT DESCRIPTION

input signal to these transistors is high for narrow band channels. Therefore, with narrow band channels, D14/D16 are forward biased and D13/D15 reverse biased and vice versa for wideband channels.

The450kHzsignalfromthesefiltersisthenfed backintoIC3onpin5andappliedtoalimiteramplifier stage. From the limiter the signal is fed to the quadrature detector. An external phase-shift network connected to pins 10 and 11 shifts the phase of one of the detector inputs by 90° at 450 kHz (the other inputs are unshifted in phase). This network consists of C17 and ceramic discriminator X1. The detector is adjusted for wide and narrow band channels by Q3, R8, and C16. The detected audio signal is then amplified and fed out of IC3 on pin 9.

4.3.3 SQUELCH CIRCUIT (IC4A/B, IC5A)

The audio output signal on pin 9 of IC3 contains audio and also high-frequency noise. This signal is fed to the receive audio and data processing circuits on the logic board (Section 4.6.1) and also to the squelch circuit. The amount of noise in this signal tends to be inversely proportional to signal strength (the higher the noise level, the lower the signal strength and vice versa). Therefore, it can be used for squelch control.

A bandpass filter that passes only noise frequencies occurring above the audio band is formed by an op amp in IC3 and external components. The input to this filter is pin 8 and frequency determining components (R17-R19, C20, C21) are connected to pin 7. Other components on the input such as Q4 provide frequency and wide/narrow band compensation, and thermistors R14/R26 provide temperature compensation. The input audio/noise level is adjusted by R13. The detected noise output on pin 13 of IC3 is applied to pin 32 of the microprocessor in the logic unit.

4.4 TRANSMITTER DESCRIPTION

NOTE: A block diagram of the RF and logic units is located on page 8-3.

4.4.1 AMPLIFIER (Q9), DRIVER (Q8)

In the transmit mode, the VCO output signal is the transmit frequency. It is switched to the transmitter

by the switching circuit consisting of D7 and other components (see Section 4.2.2) and applied to amplifier Q9. Power to this stage and also Q8 is the 7.5-volt battery supply switched by Q16 and Q 17. This switch is controlled by the switched T5V supply. Therefore, when the transmit mode is selected, the TX5V supply goes high which causes the output of Q17 to go low and turn switch Q16 on.

The output signal from Q9 is fed to driver Q8 which provides additional amplification. Impedance matching with IC1 is provided by L15, C62, and a resistive pad consisting of R41-R43. Power amplifier module IC1 provides up to 3 watts of RF power at the antenna jack. It contains three internal amplifier stages, each of which has a separate supply voltage (VCC1-VCC3). The supply voltage to the first stage (VCC1) is from the power control circuit, and the supply voltage to the last two stages (VCC2/VCC3) is the unswitched battery supply.

4.4.2 ANTENNA SWITCH AND LOW-PASS

FILTER

The antenna is switched between the receiver and transmitter by an antenna switch consisting of D11, D1-D3, and several other components. In the transmit mode, the TMUT input on pin 2 of Q7 is high. The T5V supply on pin 4 then appears on pin 3 and current flows through R20, L14, D11, D3, and L1/D1 and L2/D2. Since D11 and D3 are forward biased, the transmit signal has a low impedance path to the antenna.

L14/C31, L1/C2/D1, and L2/D2/C17 each form discrete quarter-wave line that is AC grounded at one end. When one end of a quarter-wave line is AC grounded, the other end presents a high impedance to the quarter-wave frequency. Therefore, L14/C31 isolate the 5-volt battery supply from transmitter RF, and the other two circuits isolate the receiver. In the receive mode, D11 and D1-D3 are no longer forward biased. Therefore, the receive signal has a highimpedance path into the transmitter and a low-impedance path into the receiver. From the antenna switch the transmit signal is fed to low-pass filter FI7. This filter attenuatesharmonic frequencies occurring above the transmit band.

CIRCUIT DESCRIPTION

4.4.3 POWER CONTROL (IC2A/B)

The power output circuit maintains a steady power output level by controlling the supply voltage to the first stage in power module IC1 (VCC1). The output power is m onitored using a directional coupler consisting of L34, L13, C33, C35, D4, D5, and several other components. Reflected (reverse) power is detected by L13/D5, and forward power is detected by L12/D4. These couplers produce a DC voltage that is proportional to the reverse or forward power.

The forward power signal is amplified by IC2A and is combined with the reverse power signal on pin 6 of IC2B. If there is no reverse power being detected, IC2B amplifies only the difference between the forward power signal on pin 6 and the reference voltage on pin 5. This reference voltage controls the power output, and it is set by the control logic through potentiometer 2 in IC209 in the logic unit.

As forward or reverse power increases, the output voltage on pin 7 decreases. Q5 and Q6 then turn off more which decreases the supply voltage applied to VCC1 of IC1. Power then decreases to maintain a stable output. The opposite occurs if forward or reverse power decrease. The power decrease resulting from an increase in reverse power prevents transmitter damage which may result if excessive power is reflected back into the transmitter. This may occur, for example, if the transmitter is keyed with a defective antenna.

4.5 CONTROL LOGIC AND DISPLAY

NOTE: A block diagram of the RF and logic units is located on page 8-3.

4.5.1 CONTROL LOGIC

The digital control logic is based on 8-bit CMOS microprocessor IC306. The operating speed is set by

9.8304 MHz crystal X2. A clock shift signal applied through D301. This signal goes high to shift the clock frequency slightly when the second harmonic interferes with the receive signal.

A serial data bus formed by MSI, MSO, and MSCK (pins 49-51) is used to transfer data to and

from two external devices. They are 16K x 8 EEPROM IC304 and DTMF encoder IC303. Another serial port formed by XTXD and XRXD is used to transfer programming data to and from an external computer. This port is fed out of the transceiver on pins 6 and 7 of the accessory connector. Descriptions of the IC306 pins are located in Table 4-1.

4.5.2 DISPLAY ASSEMBLY DESCRIPTION

IC1 on the display board is an intelligent LCD display controller/driver. It communicates with the microprocessor on the logic board over a serial bus consisting of MSCK (serial clock) and MSO (serial data), and DISST (display strobe) signals. IC1 is set for 1/3 bias and 1/5 duty cycle and drives an 8-character, 14-segment display a t a 98 Hz frame frequency. The LCD display (DS6) has 127 segments that are driven by a 34-segment signal with 4 common lines.

4.6 RECEIVE AUDIO PROCESSING

4.6.1 BANDPASS FILTER (IC101)

The receive audio and data signal from the IF module in the RF unit is called DET. It is applied to IC101 in the receive audio circuit, IC102 in the receive data circuit, and IC110 in the SMARTNET data circuit. The receive audio circuit operates as follows, and the other circuits are described in later sections.

The DET signal is applied to IC101 which is a bandpass filter which passes frequencies from 3003000 Hz. This attenuates Call Guard (CTCSS/DCS) signaling and high-frequency harmonics. This filter also provides de-emphasis of the audio signal.

On the input of IC101, pin 1 of Q110 is low in the wideband mode and high in the narrow band mode. Therefore, R102 is grounded in the wideband mode to lower the input level to IC101. This maintains a constant audio output level since the higher deviation in the wideband mode results in a higher input level. Also on the input of IC101, the NPSPAC line controlling Q111 is high w hen a NPSPAC channel is selected and low at other times. This grounds R167 in the NPSPAC mode to lower the input l evel since NPSPAC channel deviation is higher than narrow band deviation.

From this filter the signal is fed to pin 7 of the expander in IC208. When companding is enabled by a low input on the PT input of IC208, this stage provides 1:2 expansion of the audio signal to remove the 2:1 compression that occurred when it was transmitted.

cation. However, when an external speaker-microphone is connected to pin 1 of the accessory jack (a load of approximately 1k ohm or less), Q102 and Q105 turn on and Q109 turns off. This disables IC105

and IC106, and enables IC104. This compression and then expansion reduces the amount of noise present in the audio signal. When the PT input is high, companding is disabled and the signal if fed through IC208 without expansion. NOTE:

Companding is not currently used with this radio.

The supply voltage to all three audio amplifier stages is controlled by Q106 and Q 107. When the audio is muted such as when no tones are sounding or no message is being received, the AMUT output of the microprocessor (pin 85) is low. This turns off both

Muting of the DTMF tones is provided by Q101 which is controlled by the DTMFMT output (pin 82) of the microprocessor. The beep tones are synthesized by the BEEP output (pin

The input level to the audio amplifiers is also controlled by Q112 which lowers the input level by grounding R168. Both the NPSPAC and W/B (wide/ narrow band) lines control Q112. Resistor R168 is grounded only in the narrow band/non-NPSPAC mode (see preceding information for line levels).

CIRCUIT DESCRIPTION

cut-off frequency is approximately 190 Hz. Q103 lowers the cut-off frequency of the filter by switching additional capacitance into the filter.

From the filter the data signal is applied to a DC restoration circuit formed by IC107B and IC107A. This circuit converts the data signal from AC floating at half supply to a digital signal at 0- and 5-volt levels that can be read by the microprocessor. IC107B is a standard noninverting amplifier with a gain of approximately 5.6 set by R139 and R140 (R140 is AC grounded by C129). Diodes D101 and D102 charge and discharge C129 to establish a DC reference on pins 2 and 6 of IC107 that is the average of the positive and negative going alternations of the data signal.

The amplified data signal is applied to pin 3 of IC107A. When this level rises above the reference level on pin 2, the output on pin 1 goes high (5 volts). Conversely, when the data signal falls below the reference level, the output goes low (0 volts). In the transmit mode, Q104 is turned on which effectively grounds pin 3 of IC107A and forces the output on pin 1 low.

4.7.2 TRANSMIT DATA FILTER (IC206B/

IC206A)

Thetransmitdatasignalisproducedbythe TXDATA and TXPREC outputs of the microprocessor (pins 27 and 34, see Table 4-1). A pseudo sine wave is produced by the four voltage levels that can be produced by these outputs. This signal is fed to a transmit data filter formed by IC206B and IC206A. This filter is the same as receive data filter IC102B and IC102A described in the preceding section. This filter attenuates harmonics present in the waveform produced by the microprocessor.

The output and input of the data filter is fed to gate IC203. This gate is used to bypass the transmit data circuit during alignment so that a wide range of harmonic frequencies are passed for use in setting modulation balance. The control signal to this gate is the TEST signal from pin 35 of the microprocessor. This signal is low when the transmit data filter is bypassed.

Thesignalisthenroutedtopin7orgateIC210 which selects either it or the SMARTNET data signal

from IC113B. The data output signal on IC210, pin 1 is then applied to pin 24 of IC209 which is the input to one of the digitally controlled potentiometers in that device. The data m odulation level is set during alignment and controlled by the logic. The output on pins 22 and 23 is then fed to IC201 where it is combined with the transmit audio signal (see Section 4.8.3).

4.8 TRANSMIT AUDIO PROCESSING

4.8.1 GATE (IC204), HIGH-PASS FILTER (IC202)

The microphone audio signal is applied to pin 2 of one of the gates in IC204. This signal may come from the internal microphone or an external microphone connected to pin 8 of the accessory connector. This gate is controlled by the MMUTE signal from pin 33 or the microprocessor. When this signal is low, the microphone audio signal is muted.

The transmit DTMF tone is applied to pin 6 of IC204 which is the input of the other gate in that device. This gate is controlled by the DTMFMT signal from pin 82 of the microprocessor, and when that signal is low, the DTMF tone is muted.

The transmit audio and DTMF signals are then combined and applied to pin 3 of compandor IC208. When companding is enabled by a low input on the PT input of IC208, this stage provides 2:1 compression of the audio signal. This compression and then re-expansion when it is received reduces the amount of noise present in the audio signal. When the PT input of IC208 is high, companding is disabled and the signal is fed through IC208 without compression. NOTE:

Companding is not currently used with this radio.

The transmit audio/DTMF signal is fed out of IC208 on pin 2 and applied to a high-pass filter formed by IC202A. This filter has a –3 dB cutoff frequency of approximately 300 Hz to attenuate frequencies that could cause interference with the Call Guard signals.*

4.8.2 LIMITER (IC202B)

Pre-emphasis of the DTMF tone or microphone audio signals is provided by C205/ R211. IC202B is an amplifier functioning as a limiter (limiting occurs when it saturates). Limiting prevents overmodulation

CIRCUIT DESCRIPTION

caused by high input levels from t he internal or external microphone. The bias voltage to this stage and also to IC201A is produced by voltage divider R208/R207.

4.8.3 LOW-PASS FILTER (IC205A/B)

IC205A and IC205B form a low-pass splatter filter which attenuates frequencies above approximately 3 kHz. This prevents adjacent channel interference caused by the harmonic frequencies which result from amplitude limiting.

The output signal from this filter is applied to IC209 which contains four logic-controlled potentiometers. The transmit audio signal is applied to potentiometer3onpin20andfedoutonpin19whichisthe wiper of that potentiometer. The potentiometers in this device are adjusted by the control logic via the serial data bus (MSCK/MSO). The transmit audio/DTMF level is set when the transceiver is aligned.

The transmit audio/DTMF signal is then fed to IC201 where it is combined with the transmit data/ SMARTNET data signal if applicable. The output signal on pin 4 of IC201 is then fed to the VCO in the RFunitandalsotopins7and8ofIC209.Thesignal fed to the RF unit (MOD) modulates the VCO, and the signal fed to IC209 is level adjusted and fed out on pin 6 and applied to the RF unit where it modulates the TCXO. The potentiometer is set by the logic during alignment, and is used to balance the VCO and TCXO modulation signals.

4.9 SMARTNET DATA PROCESSING

is provided by gate IC110 which is controlled by the SN_TR signal from pin 95 of the microprocessor. When this signal is high, the transmit data signal on pin6isselectedisroutedtothefilter,andwhenitis low the receive data signal on pin 7 is r outed to the filter.

IC112B, IC112A, and IC113B form a 1800 Hz low-pass filter which attenuates unwanted frequencies above the SMARTNET/SmartZone data band. The output of this filter on U113B, pin 7 is then fed to IC114A/B which provide DC restoration when data is being received. The signal is also fed to gate IC210 in the transmit data circuit to be transmitted when applicable.

The DC restoration circuit formed by IC114A/B and IC113A is similar to the receive data circuit described in Section 4.7.1. It converts the data signal from AC floating at half supply to DC levels of 0 and 5 volts that can be detected by the microprocessor. Diodes D104 and D105 charge and discharge C158 andC157toestablishaDCreferenceonpin2of comparator IC113A that is the average of the positive and negative going alternations. Q106 turns on in the transmit mode which grounds pin 2 and disables this circuit.

In the transmit mode, gate IC210 selects either the SMARTNET data signal or the Call Guard data signal. It is c ontrolled by the same SN_TR signal that controls IC110. The output signal on pin 1 is then applied to potentiometer 1 in IC209. Refer to Section

4.7.2 for more information on this circuit.

Both the transmit and receive SMARTNET/ SmartZone data signals are applied to a filter formed by IC112A/B and IC113B. Switching of these signals

BATTERY PACK AND CHARGER INFORMATION

SECTION 5 BATTERY PACK AND CHARGER INFORMATION

5.1 BATTERY PACK

CAUTION

Disposeof these batteriesin accordancewith localregulations.Donot disposein aland fill.Do notincinerate because an explosion may result.

5.1.1 GENERAL

Standard 1400 mAH Battery Pack, Part Number 587-8150-135, contains six size AA nickel metalhydride (Ni-MH) batteries connected in series. Also inside the pack are a diode, thermistor, and thermal circuit breaker. The diode protects against reverse polarity when charging and also prevents discharge of the battery through the charger. The thermistor is used by the rapid charger to sense battery temperature.

Intrinsically Safe 1400 mAH Battery Pack, Part Number 587-8150-136, is similar t o the standard pack except that it has a thermal fuse and series resistors connected to the negative terminal of the battery. This resistor limits current if a short circuit occurs.

• Repeated deep discharge. Recharging should take

place soon after the low battery indication appears. This indication appears when the battery pack voltage drops to 6.3 volts which is approximately 1 volt per cell. Do not regularly continue operating the transceiver until it is completely nonfunctional.

• Regularly recharging a battery after only light use.

This may result in shortened operating time. If this has caused shortened operating time, it may be possible to restore it to normal by performing three complete discharge/charge cycles.

• Frequent use at temperature extremes. Maximum

battery life is achieved if the ambient temperature when using or recharging a battery is 68-86° F (2030° C). The recommended temperature ranges for the various battery functions are as follows.

Function Fahrenheit Celsius

Charging +50 to +104° +10 to +40° Actual Use +14 to +140° –10 to +60° Storage –22 to +122° –30 to +50°

The battery pack is a sealed unit that is not intended to be serviced. If the pack fails to hold a chargeor is defective for some other reason, it must be replaced with a new unit. The batteries in this pack have a nominal capacity of 1400 mAH. Typical operatingtimebeforerechargeisasfollows.Thisassumes that the transceiver is in the standby mode (receive, audio squelched) 90% of the time, the receive mode (receive, rated audio out) 5% of the time, and the transmit mode 5% of the time.

Power Setting Operating Time

1 watt 8.6 hours 3 watts 7.5 hours

5.1.2 BATTERY CARE

With proper care, a battery pack should provide many months of service. Some causes of shortened battery life are as follows:

• Regularly leaving fully charged battery packs in the

charger for extended periods (such as longer than over a weekend).

• A short circuit condition that causes overheating

that could vent hydrogen and reduce life.

5.2 RAPID CHARGER

The single-unit rapid charger that is used to charge this battery pack is listed in Table 1-1. Also required is either the 117 or 220 VAC power supply. The pack can be charged while attached to the transceiver; however, charge time may be slightly longer. Typical charge time is as follows. This assumes t hat the battery is discharged to the point where the low battery indication appears.

BATTERY PACK AND CHARGER INFORMATION

change in voltage) sensing to determine when the battery is nearly fully charged. This type of sensing prolongs battery pack life because overcharging is minimized.

Operation is in the fast charge mode until the battery pack is approximately 95% charged. Charging is then in the slow mode until the pack is removed from the charger. With t hese battery packs, the fast rate is approximately 1400 mA and the slow rate is approximately 70 mA.

When the battery is inserted in the charger, the red charge indicator turns on continuously to indicate that charging in the fast mode is occurring. If this indicator flashes at a slow rate when the pack is inserted, it indicates that charging is occurring at the slow rate because battery parameters are not within the required range. The battery temperature must be within +50 to +104° F (+10 to +40° C) and the battery voltage must be above 6 volts for rapid charging to occur. When these parameters reach the normal range, the charger automatically switches to the fast rate.

The primary method used by these chargers to detect a fully charged battery is to sense the point at which the battery temperature begins increasing at a faster rate (

∆T/∆t). This normally provides the first

indication that the battery is f ully charged. If this method does not indicate a charged battery, the charger also detects a negative change in battery voltage (minus

∆V) which also indicates a fully charged

battery.

To provide fail-safe operation, the charger also switches to the slow rate if the battery temperature rises above approximately 113° F or total charge time in the fast mode exceeds approximately 1.5 hours.

When the battery is fully charged, the charge indicator begins flashing at a rapid rate and the slow charge rate is selected. The charger then remains in this mode until the battery is removed from the charger.

6.1 GENERAL

6.1.1 INTRODUCTION

The alignment procedure described in this section should be performed if repairs are made that could affect the factory alignment. In addition, before a transceiver is initially placed in service, the performance tests in Sections 6.8 and 6.9 should be performed.

To perform the alignment described in this section, special PCTune software (see Table 1-1) and the same basic computer setup used for programming is required. This equipment is shown above and also described in Section 3.1. Only Remote Programming Interface (RPI), Part No. 023-9800-000, can be used because it is the only RPI that has microphone and speaker audio jacks that are required for alignment.

Wattmeter

Only two adjustments are made manually and the others are made digitally using the PCTune software. The two manual adjustments are squelch sensitivity and TCXO frequency, and if they do not need to be reset, the transceiver can be tuned without removing the cover.

This transceiver does not have a special test mode that is selected. The PCTune software automatically selects the frequencies and other test conditions that are required to perform the alignment. If the transceiver must be controlled manually to perform such things as testing or troubleshooting, program temporary conventional channels.

6.1.2 TEST SETUP

2. Monitor the transmit modulation signal with a communicationmonitor and follow the instructions on the screen to adjust the wideband, narrow band, and SMARTNET/SmartZone control channel data deviation.

6.6 SQUELCH ADJUST

The input level to the noise squelch circuit is set by R13 on the IF board, and the squelch threshold level is set by the PCTune s oftware. The factory setting of R13 should not need to be changed, so step 3

which follows can normally be skipped. Proceed as follows to set the squelch:

1. If manually selecting each test, click the “Tune” button in the “Squelch” box. Otherwise, this function is selected automatically when the “Complete Tune” button is clicked.

2. Connect an RF signal generator to the antenna jack using a 6 dB or greater pad. Set the generator for the channel frequency and modulation indicated on the screen.

3. If R 13 must be adjusted (see preceding), removethe transceivercover and connect power as describedin Section 6.1.6. Temporarily set the squelch for “50” on the “Squelch” screen and adjust R13 (see Figure 6-3)so that thesquelch just opens (audio isheard) at 8-9 dB SINAD.

4. Readjustthe squelchlevel as indicated on thescreen so that the squelch opens and closes between the indicated SINAD levels.

6.7 RSSI ADJUST

NOTE: Improperlysetting the RSSI levels can resultin degraded SmartZone roaming operation. Therefore, do not change the default settings unless you are familiar with how roaming will be affected.

The function which adjusts the RSSI levels is available only by clicking the “Tune” button in the “RSSI” box. It is not displayed in the Complete Tune mode for the reason just described. The default values that are programmed by clicking the “Program Defaults” button (see Section 6.1.5) should not be changed unless you are familiar with how these levels control site switching in a SmartZone system.

PERFORMANCE TESTS

6.8 RECEIVER PERFORMANCE TESTS

6.8.1 PRELIMINARY SETUP

This transceiver does not have a special test mode that can be selected to perform testing. Therefore, temporary conventional channels are programmed to perform this function. Program channels near the low, middle, and high ends of the band (wideband, narrow band or both) and with and without Call Guard (CTCSS/DCS) squelch as applicable. In addition, to check high and low power and talk-around operation, program High/Low Power and Repeater Talk-Around option switches. Proceed as follows to check receiver operation:

1. Select the channel near the center of the band

(around 860 MHz).

2. Connectthe signal generatorto the antennajack (see

Section 6.1.2 for more information). Set the output to the channel frequency, modulated with 1 kHz at 3 kHz (wideband channels) or 1.5 kHz deviation (narrow band channels).

6.8.2 SINAD SENSITIVITY

6.8.3 SQUELCH SENSITIVITY

With the test setup used for the preceding test, slowly increase the signal generator output until the squelch just opens (audio is enabled). Then decrease the signal generator output until it just closes. The squelch should open after 12 dB SINAD and close before 6 dB SINAD.

6.8.4 AUDIO POWER AND DISTORTION

CAUTION

Grounding either speaker terminal may damage the audio amplifier. Therefore, make sure that any meter connected across the speaker has floating inputs.

To measure audio output power, the actual level across the speaker must be measured because full output power is not available at the accessory connector. If a load of approximately 1k ohm or less is connected to the speaker output of the accessory connector, it must be disconnected to enable the internal speaker. Proceed as follows:

NOTE: The audio output level of the accessory connector is at a lower level than at the internal speaker. In addition, the internal speaker automatically mutes when a load of approximately 1k ohm or less is connected to this output.

1. Connecta SINAD meter to the speaker output of the RPI (see Section 6.1.2).

2. Decrease the signal generator output to obtain a 12 dB reading on the SINAD meter. The signal generator output should be 0.35 µV maximum. If required, temporarily readjust squelch for “0” as describedin Section 6.6. (after clicking “Read Tune Settings” to note the current setting).

3. Check both wide and narrow band channels if applicable, and also check the channels on each end of the band. Reset the squelch to the previous level if it was changed.

1. Remove the transceiver cover and connect power as described in Section 6.1.6. Carefully turn the front cover over to access the speaker.

2. Connect an AC voltmeter and distortion meter across the speaker (make sure they have floating inputs). Alternatively, 100 µF, non-polarized capacitors can be used in series with the leads.

3. Set the signal generator output for –60 dBm (220 µV). Minimum audio power should be 0.5 watt across the 16-ohm speaker (2.8 V r ms). Distortion should be less than 5% at 0.5 watt.

6.8.5 RECEIVER CURRENT DRAIN

Maximum transceiver current with 0.5-watt audio output is 300 mA. With the receiver squelched, it should be 92 mA maximum.
