EUROPEAN STANDARDS:

Safety Not Applicable EMC: prETS 300 279 (August 1995) TTD: Not Applicable

SUPPLEMENT ARY INFORMATION

At this time, the M-RK port able radio may not be operated while in a vehicular charger in the European Community since it does not meet immunity requirements when operated in this mode.

The M-RK portable radio may be used in both trunked and conv entional applications.

SAFETY INFORMATION

The Federal Communications Commission (FCC), with its action in General Docket 79-144, March 13, 1985, has adopted a safety standard for the human exposure to radio frequency (RF) electromagnetic energy emitted by FCC regulated equipment. Pr oper operation of this radio will result in user exposure far below the Occupational Safety and Health Act and Federal Communication Commission limits.

DO NOT

BATTERY CHARGING AND CARE

Do not dispose of the battery pack in fire - it may

explode, causing injury or death.

Do not replace the battery in hazardous atmosphere

locations.

Do not carry battery loose in your pocket or purse. Do not attempt to repair battery.

The product you have purchased contains a rechargeable, recyclable battery. At the end of its useful life under various state and local laws it may be illegal to dispose of this batter y into the municipal waste stream. Check with your local solid waste officials for details concerning recycling options or proper

disposal in your area. Call Toll Free 1-800-8- BATTERY for information and/or procedures for returning rechargeable batteries in your state.

Your radio comes supplied with a Ni-Cd battery pack which can be recharged from 500 to 1000 times before requiring replacement. The actual number of charge/recharge cycles vary depending upon usage. We recommend that the battery be charged 14 to 16 hours on the first charge cycle and then in accordance with the charger model instructions thereafter.

To remove the battery pack, push up on the battery latch and slide the battery pack to the right. To replace the battery , align the battery on the track and slide to the left until a click is heard, indicating the battery is correctly installed.

Figure 1 - Installing And Removing The Battery Pack

If the battery is to be charged on the radio, turn the power switch on the radio to the off position before charging. F ailing to turn the power s witch to off during the charge cycle will result in a less than full charge condition, which will noticeably reduce the operating time between charges!

Normal battery operation time is 8 hours. This may vary depending upon how much the receiver audio is present and how much you transmit. The actual time may vary from day to day depending upon operational requirements.

FOR BEST PERFORMANCE

1. Charge battery to full capacity , 14 hours at the standard C/10 rate (capacity X .10). For "rapid" chargers, allow additional time (2-3 hours) for "topping off" the charge after it switches from "fast" to "slow".

2. Use the battery soon and use as much of the battery capacity as possible or practical. A battery that is charged and discharged completely will maintain the longest running time capacity. Also, several charge/discharge cycles are recommended to bring a new battery up to its rated capacity.

3. Store and charge the batteries at room temperature 65°F to 75°F. Batteries that have been stored f or over a month should be recharged before putting into service due to chemical self-discharge which occurs at a rate of approximately 1% per da y. Do not charge cold batteries (40°F or below).

4. Reduced capacity or "memory effect" may result from repeated identical shallow discharge/full recharge cycles. If such a condition is suspected, run the battery until the instrumentation loses all power, then fully recharge and discharge again. Repeat this cycle 3-4 times.

EXTENDED OPERATIONS

When operating in "Fringe Areas" at some distance from the System, the other par ty may not receive your transmission clearly . Also, you may notice that the background noise will increase on received signals. Moving to higher ground or moving closer to the System will help alleviate these problems. If moving closer to the System is not practical, communication may be improved by moving away from shielding structures. If you are in a building interior, mo ve closer to a window (preferab ly one generally in the direction of the System). At 800 MHz the wave length is very short, sometimes moving a few inches to a few feet can mak e significant signal strength changes. Finding the best location can also be done while listening to the background noise while moving about; attempt to find a spot where the background noise is reduced to a minimum or eliminated entirely. This may make the difference from not being heard, to being heard loud and clear when operating in the fringe areas of your System coverage.

The fringe distance will vary greatly from plains areas , hilly terrain and mountain top sites.

FCC LICENSING

This unit may or may not require a specific FCC license to operate. The FCC requires all tr ansmitters in the conventional and some Trunked Systems to be licensed by the F ederal Communications Commission. Some Tr unked operations a re now exempt from in dividual licen sin g r e qu ir e me nt s but must be op erat ed in a licensed System.

Consult your dealer regarding specific licensing information, or contact the Federal Communications Commission.

For more information regarding the FCC license application (Form 571), call 717-337-1212, or contact the FCC District Office nearest your location.

TRANSCEIVER SERVICE

There are no user serviceable components inside the radio. Altering the inter nal components or adjustments may result in illegal emissions, including off-frequency operation, or damage to the radio.

Should an display , or the LCD f ails to display information, or all icons and display segments are shown, turn the POWER ON-OFF/VOLUME control OFF then ON to reset the microprocessor. Ensure that the battery is fully charged and check that the antenna is securely tightened.

If the unit still fails to operate properly, refer to an Authorized Service Center for servicing.

INTRODUCTION

This manual describes how to use the EDA CS M-RK II Portable Radio. The M-RK II is a synthesized, micr oprocessor-based, high performance portable FM radio providing reliable two-way communications in both the Enhanced Digital Access Communications System (EDACS) trunking environment and conventional communication systems.

In the EDACS or trunked system mode, the user selects a communications system and group. In this mode, channel selection is transparent to the user and is controlled via digital communication with the system controller. This provides advanced programmable features and fast access to communication channels.

In the conventional mode, the user selects a channel and directly communicates on that channel. In this mode, a system refers to a set of channels. A channel is a transmit/receive radio frequency pair.

The exact operation of the radio will depend on the operating mode, the radio’s programming, and the particular radio system. Most features described in this manual may be enabled or disabled through programming. Consult the system administrator f or the particular features that are programmed into the M-RK II.

USER INTERFACE

The M-RK II operating controls are located on the radio’s front, top and left panels. A 15-button keypad, liquid crystal display (LCD) for radio status information, microphone and speaker are on the front panel. The top panel houses a rotary SYSTEM/GROUP/CHANNEL knob, POWER ON-OFF/VOLUME control knob and a protected red EMERGENCY button. An OPTION button, CLEAR/MONITOR button and the Push-To-Talk (PTT) button are all located on the left side panel. The Universal Device Connector (UDC) is located on the right panel and is used while programming the radio and for accessory connection.

The keypad is used for manual number entry for individual calls, access to a telephone interconnect system, and activation of various EDACS or conventional features such as menu selection or scan operations.

The display has two, eight-alphanumeric-character lines used to show the operational mode of the radio. Fifteen status indicators, used to indicate various operating conditions such as transmitter on, channel busy, scanning, or low battery, are located above and to the right side of the character lines within the display. A back light illuminates the display and the k eypad for nighttime use.

UNIVERSAL DEVICE CONNECTOR (UDC)

The Universal Device Connector (UDC) provides connections for external accessories such as a headset or a speaker-microphone. When the radio is locked in a vehicular charger/repeater, the UDC provides the audio and control connections between the radio and the vehicular charger/repeater. The UDC is also used to program and service the radio.

ALERT T ONES

The M-RK II radio also provides audible alert tones or "beeps" to indicate the various operating conditions. These alert tones can be enabled or disabled through programming.

Call Originate

A short mid-pitched alert tone sounds after keying the radio (Push-T o-Talk button is pressed). This indicates the radio has been assigned a working channel or that the radio is transmitting on a conventional channel and voice communication may begin immediately. In conventional mode, this tone may be delayed after the PTT button is pressed due to GE-STA R signalling (if enabled through programming).

Autokey (Trunked Mode Only)

After being placed in queue or releasing the PTT button prior to a working channel assignment, the site calls the radio when a channel becomes available. At this point, the radio automatically keys the transmitter (autokey) for a short period to hold the channel. The radio sounds a mid-pitched tone when it is clear to talk; immediately press the PTT button to keep the assigned channel.

Call Queued (Trunked Mode Only)

A high-pitched tone after pressing the PTT button indicates the system has placed the call request in the queue. The receiving unit(s) also hear the tones, indicating they will receive a call shortly . If the the PTT button is

released, the radio will autokey whenever a channel becomes available (see Autokey).

System Busy (Trunked Mode Only)

Three low-pitched beeps will be heard if the radio is keyed when the system is busy, if no channels are available for sending the message, if the call queue is full, or if an individual call is being attempted to a radio that is transmitting. Releasing the PTT button and reke ying initiates a new channel request.

Call Denied (Trunked Mode Only)

If the radio is keyed and a low pitched tone is heard then the radio is not authorized on the system that has been selected.

Carrier Control Timer

If the programmed time for continuous transmission is exceeded, five short high-pitched warning tones followed by a long low-pitched tone will be heard. The transmitter will shut down shortly after hearing the alert, interrupting communications. Release and re-key the PTT button to maintain communications. This will reset the carrier control timer and turn the transmitter back on.

Low Battery W arning

A low-pitched tone is heard and comes on indicating that the battery voltage is low. The radio will continue to receive and transmit.

BA T

Low Battery Alert (Transmit Lockout)

If the radio is keyed and the user hears either a low-pitched tone or two tones and the LOW BATT status indicator is displayed, the battery is discharged and the radio will not transmit. Pressing the PTT or CLEAR button will reset the LOW BATT status indicator if either is pre-programmed to perform this function. The radio will still be able to receive calls until the batter y is discharged beyond the point of operation, after which the battery will need to be recharged to resume normal operation.

Key Press Alert

A short tone or "beep" sounds to indicate a key has been pressed. A short low-pitched tone indicates no action was taken because the key is not active in the current mode.

EMERGENCY/HOME BUTTON DEFINITION

The EMERGENCY/HOME button can be pro-

grammed in one of the following conditions:

1. Emergency Enabled and Home Enab led - The radio will switch to the programmed home System and/or Group and send an emergency transmission.

2. E mergency Enable and Home Disabled - The radio will send an emergency transmission on the current System/Group.

3. Emergency Disab led and Home Enabled - The radio will switch to the home System and/or Group.

4. E mergency Disabled and Home Disabled - the button is not active.

Home

The radio can be programmed to automatically switch to a home System and/or Group by pressing and holding the EMERGENCY/HOME button for the pre-programmed duration. The radio will also transmit an emergency message on the home System and/or Group if programmed (see the Emergency Operation section).

AEGIS AND VOICE GUARD OPERATION Voice Modes

Each system (trunked or conventional) in the radio is programmed for either Aegis or Voice Guard communications. Aegis programmed systems have three (3) different voice modes: clear (analog), digital and private. Voice Guard systems have two (2) voice modes: clear (analog) and private. The voice modes are programmed on a per-group basis within each trunked system and on a per-channel basis within each conventional system. A radio must be equipped with the encrypt/decr ypt option before it will operate in Aegis or Voice Guard modes.

NOTE

Conventional Aegis or encrypted channels require Channel Guard on the channel to operate correctly.

Clear Modes

Aegis clear and Voice Guard clear modes are identical voice modes in which the radio transmits and receives only clear (analog) voice signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be easily monitored by unauthorized persons. Groups or channels programmed for clear operation cannot transmit or receive Aegis digital or private messages.

Aegis Digital Mode

Aegis digital mode allows the radio to transmit and receive digitized voice signals. Aegis digital signals pro-

vide improved weak signal performance and they cannot be easily monitored with a standard receiver. Groups and channels programmed for Aegis digital operation transmit only digital signals. Private calls cannot be received or transmitted when the radio is in the Aegis digital mode because the radio does not know the cryptographic key used. Message trunked group calls and individual calls will be answered back in the mode they were received, assuming the call or hangtime is still active. Individual, phone, all and emergency calls will be transmitted clear if digital mode is disabled or inoperative.

1. If receiving an analog message trunked call, the radio will respond in analog mode during the hang time on the working channel.

2. If receiving an analog I-Call, the radio will respond in analog mode during the hang time.

3. When using the "WHC" feature to respond to an I-Call (after the hang time has expired), the call will be transmitted in the mode defined by the system mode as programmed for the current system if the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call will be transmitted as defined by the I-Call mode programmed in the list for that ID.

DTMF

The overdial and hot ke ypad f eatures f or tr ansmitting DTMF tones are not available while in the Aegis Digital Mode.

Error Messages

If either of the following error messages is display ed, the radio was either programmed incorrectly or needs servicing:

DSP ERR ERR=xxxx

DSP ERR

Po wer Up Only

If the Aegis circuit board is not responding, the following error message will be displayed and the radio needs servicing:

HARDWARE ERR= 30

AEGIS PRIV ATE AND VOICE GUARD PRIVATE MODES

The Aegis private and Voice Guard private modes allow the radio to transmit encrypted messages and receive clear or private transmissions. The radio will transmit private if the group/channel is programmed for private operation and forced operation is pre-programmed. If autoselect operation was pre-programmed and the radio is in private mode, the radio will transmit in the mode of the received call if the hang time is active. If no hang time is active, the radio will transmit private.

Aegis transmissions cannot be received by a radio set to receive a Voice Guard transmission. Accordingly, a V oice Guard transmission cannot be received by a radio set to receive an Aegis transmission.

Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An individual key is automatically selected on a per-group/channel basis according to the radio’s programming. Groups and channels within Aegis systems can be programmed for keys 1-7. Groups and channels within Voice Guard systems can be programmed for keys 1-7. Up to 8 banks of 7 keys can be stored for Aegis (DES and VGE) systems and up to 4 banks of 7 keys for V oice Guard systems. The bank is specified per system.

DES radios require a DES Keyloader (Option V4025 with software version 3.N or later). VGE radios require a VGE K eyloader (Option V4028 with software version 2.N or later).

When operating on a group or channel programmed for private mode, all transmissions will be private transmissions and the radio will receive clear and private signals. The status flag in the display turns on when the private mode is enabled. If the selected group or channel is programmed for autoselect capability, the mode may be toggled between private and clear with the PVT button. Radios programmed for forced private operation do not allow a change of the transmit mode; therefore, the PVT button has no effect.

All cryptographic keys can be zeroed (erased from radio memory) by pressing the MONITOR/CLEAR b utton and while still pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds. A series of beeps will begin at the start of this 2 second period and then switch to a solid tone after the keys have been zeroed. The display will indicate "KEY ZERO"

If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the radio before private communications may continue.

PRIVATE OPERATION Receiving An Encrypted Call

When receiving, the radio automatically switches between clear or private operation. If the transmission being received is an encrypted transmission, it will be decrypted, the status flag will flash, the receiver will unsquelch and the message will be heard in the speaker. For this to occur, the selected group or channel must be programmed for private operation and the correct cryptographic key must be loaded into the radio.

Transmitting An Encrypted Call

1. Select the desired group or channel.

2. Place the radio in private mode by pressing the

If a group or channel is not programmed for private mode operation, "PVT DIS" will be displayed if an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel in private mode.

If the radio is programmed for forced private tr ansmit operation, "FRCD PVT" will be displayed if an attempt is made to disable private transmit mode. It is not possible to transmit on this group/channel in clear mode.

If the radio does not have the correct encryption key loaded, "NO KEY #" will be displayed and the call will not be transmitted.

3. Continue with standar d transmission procedures. A private mode access tone will be heard when the PTT button is pressed.

Scanned Group Calls

Receiving a scanned group call is the same as receiving a selected group call. During the scan hang time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the call. For e xample, if a clear group is entered in the scan list, it will only receive clear calls. If the same group was available in private and entered in the scan list, it can receive clear and private calls, provided autoselect was programmed in the radio. The user can select transmitting on the scanned or selected group. If a group is entered in the scan list more than once and in different modes (clear, digital, private), only the first occurrence of the group will be used.

LAST SYSTEM/GROUP OR CHANNEL RECALL (SUPERVISORY RADIO UNITS ONLY)

This feature enables the user to recall the last selected system/group after an EDACS emergency or home function, a conventional emergency or home function or system/group key function. This feature must be pre-programmed as "Enabled" to function. For e xample, if the Home button (pre-programmed) is pressed, the radio will go to the designated Home system/group or channel. If the Home button is pressed again, the radio returns to the previous system/group or channel. At this time the user can toggle between the Home system/group or channel and the previous system/group or channel.

EDA CS TR UNKED MODE OPERATION

Digital trunking provides fast communication access at all times, even during busy hours. In this mode the operator selects a communications system and group, and the audio communication or working channel (WC) is allocated through digital signalling with the site.

RECEIVING A CALL

1. Turn on the radio by rotating the POWER ON-

OFF/VOLUME knob clockwise (out of detent). A short aler t signal (if enabled through programming) indicates the radio is ready to use.

2. The display shows the last selected or the power up

(depending on programming) system and group names and indicates if the radio has acquired the system control channel by turning on . If the radio is unable to obtain a control channel, line two shows CC SCAN and will remain off .

3. A djust the POWER ON-OFF/VOLUME knob to the

desired volume level.

4. S elect the desired system and group. The display

indicates the current system and group names.

CONVENTIONAL FAILSOFT

In the unlikely event of a failur e of the EDACS System, communications may take place in conventional failsoft mode. The radio will be automatically directed to a communications channel set up for this purpose. During this mode of operation, the control unit will display

in the alphanumeric display. An increase in activity

on the channel during conventional failsoft operation may be noticed, so be careful not to transmit until the channel is clear.

Operation during conventional failsoft will be the same as operation on a conventional system, except that

it will not be possible to select a communications c hannel, or use emergency and special call. When trunking is restored, the radio will automatically be returned to normal operation.

NOTE

Emergency and Special Call are not operational during conventional failsoft. Also, the control will not operate.

SCAT OPERATION

A SCAT (Single Channel Autonomous Trunking) System operates with the same set of features as a standard EDACS system. The only significant user change relates to the

BSY

indicator. Since only one channel, operating as both control and working channel, exists in a SCAT System, the channel is in the working channel mode. When the transmission on the channel is completed, the indicator turns OFF and indicates the return of SCAT control channel signaling.

SCANNING TRUNKED SYSTEMS

The following features allo w interaction with systems other than the selected system to meet specific customer needs. Wide Area System Scan and ProSound are mutually exclusive options; however, Priority System Scan will operate while ProSound is active.

The radio can be programmed with the following System Scan features. These features are automatically enabled upon radio power up. A key or menu option is also defined to allow the System Scan features to be toggled during radio operation. This is covered in the MENU SELECTION and PRE-PROGRAMMED KEYPAD KEY sections. The System Scan state will be maintained through system changes but will default to ON at power up.

Wide Area System Scan

The M-RK II radio may be programmed for wide area system scan operation for multi-site applications. Upon the loss of the currently selected system’s control channel, radios may be programmed to automatically scan the control channels of other systems. If a new control channel is found, the radio will switch to the new system and sound an alert tone.

ProSound

The radio may be progr ammed f or ProSound system scan operation for multi-site applications. ProSound scanning is an enhanced replacement for wide area system scanning. This algorithm insures that the radio continually receives high quality audio. When the selected system degrades to a pre-programmed level, the radio changes to the new system and sounds a tone. Should the control channel be lost completely, the radio will scan the adjacent systems until a suitable one is found.

Priority System Scan

The radio may also be programmed for priority system scan. A priority system may be assigned among the systems programmed into the radio. Radios programmed in this manner will check for the priority trunked system’ s control channel at a programmable rate ranging from 1 to 16 minutes. This priority scan timer is reset each time the PTT button is pressed or when a call is received. If the priority system control channel is found, the r adio will automatically switch to the priority system.

4. To terminate the call, momentarily press the CLEAR/MONITOR button.

DTMF Overdial/Con ventional Mo de Telephone Interconnect

Once the radio has established a connection to the public telephone system, it may be necessary to "overdial" more digits to access banking services, answering machines, credit card calls or other types of systems that

require DTMF (Dual-Tone Multi-Frequency) access digits. Overdial operation can also be used to initiate a telephone interconnect call via DTMF signalling if a dial tone has already been accessed on the system. This is the method that is used for making a telephone interconnect call while operating in the conventional mode but will also function in trunked mode if a dial tone is directly accessible. Telephone numbers and other number sequences for overdialing can be stored in the phone list when programming the radio or stored by the operator in the first ten phone list entries. These numbers are accessed by pressing mode rules.

The following steps are required to dial these numbers:

1. Follow the procedure in Sending A Telephone In- terconnect Call (Trunked Mode Only) to establish a connection to the telephone system or consult the system administrator for the procedure to access a dial tone on the trunked or conventional system.

2. Overdial numbers are transmitted using either method below:

PORTABLE DATA

When operating in the EDACS configuration, M-RK radios permit either voice or data calls to be transmitted or received. The radio can handle only one type of call at a time; however, selection of either data or voice is elected transparently by the operator through normal usage of the radio. Data communications is not supported in the conventional mode. D A TA, RS2-Type DAT A, and ProFile are EDACS enhanced, separately purchased features that when turned on can be used to configure M-RK radios.

Press lect/entry mode and follow the selection mode rules to call up a stored number from the phone list or to directly enter the overdial digits. turns on. Press PTT to send the overdial sequence once. If the number needs to be transmitted again, it must be selected or entered again (this prevents unwanted numbers from being sent the next time the PTT button is pressed during the call).

"Data" now applies to two classes of data: External Device Data Applications (Mobile Data Terminals ) and Radio Destined Data Applications (ProFile). For External Device Data Applications, both destination and

source are from applications external to the radio. For Radio Destined Data Applications (ProFile) one side of the conversation is an e xternal device (i.e ., ProFile Mangager), but the other side is now an application internal to the radio. Data applications can be common between both application classes, or specific to a data application. Each programmable data option is organized as the following:

Universal Options - Apply to ALL data applications.

•

Specific Options - Apply only to either ProFile or

•

MDT.

The radios can be connected to Mobile Data Ter minals (MDT) or to a host computer/radio. A host radio routes all data (MDT and ProFile) externally . Any RS-232 compatible device that supports the Radio Data Interface (RDI) protocol (V ersion 1.91 or higher) may be connected to the radio. Support for MDT’s or host computers is a programmable option per radio. Additionally, radio programmed for host computers may also be programmed for data only operation (no voice calls transmitted or received).

Data Displays

The following will be displayed during the various states of data mode operation:

EDACS CONVENTIONAL P1 SCAN

This feature permits the radio user to scan a pre-programmed conventional system and channel as a Priority 1 (P1) channel while the radio is selected for EDACS trunked system. If activity is detected on the conventional P1 channel, the radio will unmute and remain on this conventional channel for the prog rammable hang time.

The radio must be pre-programmed to designate a key for scan on/off operation.

DYNAMIC REGROUP OPERATION

Dynamic group operation permits multiple talk groups (up to eight) to be added to a radio via the system manager. The radio must be pre-programmed to respond to regrouping. Dynamic regrouping will not be activated in a radio until an activation message is sent by the system manager. Each radio that receives and acknowledges the regrouping instructions is successfully regrouped.

key and then the

Pressing and holding the CLEAR/MONITOR button for 2.5 seconds toggles the user into and out of the dynamic regroup groupset. A double beep will sound for

entry or exit. The display will indicate "REGRP_0x" where "x" is a digit of 1 to 8 indicating the group when dynamic regroup has been enabled by the user. If the radio is in dynamic regroup and the user selects a group that has not been regrouped, the display will show "NO ENTRY". The radio will be prevented from transmitting and receiving calls in this condition except for scanned groups.

Emergency Operation

If the pre-programmed groupset on the currently selected system contains an EMER/HOME group and the radio is in dynamic regroup, the radio will declare the emergency on the currently selected dynamic group.

MACRO KEY OPERATION

Macro key operation permits the user to accomplish a series of key strokes with a single "macro" key stroke. Up to ten (10) macro keys can be defined, each capab le of executing up to twenty (20) key strokes, to any pushbutton input (i.e., ke ypad b uttons , OPTION b utton, etc.). Each macro key can be pre-programmed to activate when pressed or when released.

A macro key may also be pre-programmed to change the key stroke sequence the next time the macro key is activated. A macro key function will be aborted if the user changes a button or knob position.

For detail operation and assignment of macro keys, contact your communications supervisor or administrator.

CONVENTIONAL MODE OPERATION

The radio functions in the conventional mode when using conventional communications channels (nontrunked). Each channel consists of a preset frequency pair for transmit and receive during repeater operation, or a single frequency for both transmit and receive during talk-around (no repeater) operation. To use this mode, the operator selects a conventional system which includes one or more conventional channels. Each conventional channel may have one or more features, such as Channel Guard, programmed when the channel is selected.

The CLEAR/MONITOR button unmutes the receiver so activity on the selected channel can be monitored. When pressed and held for approximately 3 seconds this button toggles conventional channel decoding (Channel Guard, Digital Channel Guard or T99) on and off if programmed for the selected channel.

SQUELCH ADJUST (256K & UP VERSION RADIOS ONLY)

In the conventional mode of operation, the squelch may be re-adjusted in the MENU selection mode or from a front panel key on the keypad that has been pre-programmed by the PC programming software. A default value of 9 or any user level between 1 and 16 can be selected by the PC programming software. The user can change this setting either of two ways from the front panel keys.

NOTE

A value of 16 requires a strong signal to open squelch, a value of 2 requires a very weak signal to open squelch and a value of 1 is open squelch.

NOTE

When squelch adjust feature is activated, Channel Guard, T99 decode and Scan are disabled. When the squelch adjust feature is exited, Channel Guard, T99 decode and Scan are restored to their previous states.

EMERGENCY OPERATION

If enabled, GE-STAR emergency signalling can be

transmitted when operating in the conventional mode.

This GE-ST AR signalling will transmit 5 times with a delay between each transmission. To send an emergency call on the selected conventional system and channel (or on an optionally pre-programmed conventional emergency system and channel), proceed as follows:

Press and hold the RED EMERGENCY button that is on the top of the radio in front of the antenna for approximately one second (this time is programmable and therefore could be longer or shorter; check with

the system administrator). The radio displays and proceeds to transmit the pre-programmed GESTAR emergency signalling sequence.

GE-STAR is programmed to transmit in one of the

following methods: METHOD 1: GE-STAR is transmitted on the selected

channel. If the channel is changed, the emergency signalling will continue to be transmitted on the newly selected channel.

METHOD 2: Same as METHOD 1 but the radio will lock

on to the currently selected channel. Any attempts to change the channel will be disabled.

XMIT

METHOD 3: GE-STAR is transmitted on a pre-pro-

grammed conventional emergency system and channel regardless of the selected channel. In this case the selected channel is available f or voice transmission and the radio will periodically change to

the pre-programmed emergency system and channel to send the emergency signalling and then change back to the selected channel.

METHOD 4: Same as METHOD 3 but the radio will lock

on to the pre-programmed emergency system and channel. Any attempts to change the channel will be disabled.

The emergency state can be cleared by turning the

radio off and then back on.

Using 5-Tone Signalling For Emergency Declaration

If 5-Tone signalling is defined for emergency declaration in place of GE-STAR emergency signalling, a preprogrammed tone sequence will be transmitted instead of the GE-STAR sequence. This emergency declaration functions as the GE-STAR emergency in all other respects.

TONE ENCODE TRANSMISSION

In conventional mode two keys can be defined to be tone encode triggers. If one of the pre-programmed tone encode triggers is pressed, a pre-programmed tone sequence will be transmitted on the curr ent system and channel. (See

GENCY/HOME button is used.) The indicator will light during tone transmission and a beep will sound at the end of the transmission. If enabled, audible side tones will be heard in the radio speaker as well. If PTT is pre-programmed as one of the triggers, the microphone

SCANNING CONVENTIONAL CHANNELS

Channels which have been previously added to the scan list on a per system basis may be scanned. The selected channel is scanned (if enabled through programming) whether or not it is in the scan list. Each conventional system’s channel scan list is retained in memory when the radio is turned off or when the battery pack is removed.

The scan rate will vary depending upon the number of channels in the scan list and whether or not the radio is programmed to scan for channels with decoding enabled. Fewer channels will result in a faster scan rate. If programmed for dual-priority scan operation, the priorityone, priority-two and the remaining scan list channels are scanned. Once a signal is detected and the correct encoded squelch signal is decoded (if progr ammed), the radio receives the message and displays the received scan channel. At the same time, scanning continues on the priority-one and priority-two channels. Should the priority-one or priority-two channel carrier, regardless of encoded squelch decoding, be detected while a non-priority channel is being received, the display name is

updated, or comes on and the received channel is

VOICE MODES

). Digital or private voice

switched to the priority channel. Scanning of the priorityone channel will continue if a message is being received on the priority-two channel.

While receiving a call on a non-priority or a priority two channel, the radio periodically checks the priority one and two channels. If Scan with Channel Guard is enabled, the radio will use Channel Guard to decide whether to unmute on a priority channel. The radio will stop, on squelch detection, on a priority channel. In normal operation, the radio will unmute only on detecting the correct Channel Guard; otherwise, it will remain muted until the priority channel call and hang time have ended.

An optional feature allows the radio to continue scanning upon the detection of the wrong Channel Guard on a priority channel. The user can then select the rate this channel is scanned until the call there ends.

The following procedures outline scan operations for conventional channels.

TYPE 99 DECODE (CONVENTIONAL ONLY)

If the Type 99 Decode Option has been pre-programmed, individual selective calling is possible. The radio can now decode individual, group or supergroup paging calls. Two sets of T ype 99 paging codes must be pre-programmed into the radio. When the radio decodes an appropriate T ype 99 code sequence, an alert tone and visual indicator is provided to the user. The receiver then operates as a noise squelched unit until T ype 99 is reset. Type 99 decode continues to operate during this noise squelched period. The appropriate T ype 99 alert tone will sound again if it detects a valid two-tone sequence.

Type 99 operation can be pre-programmed to be enabled or disabled using the OPTION button or a selected keypad key. Type 99 operation may be reset manually or automatically (pre-programmed). Manual reset is achieved by briefly pressing the CLEAR button. Automatic reset, if enabled, occurs after a 30 second interval following the most recent decode of a Type 99 tone sequence.

NOTE

T99 is automatically disabled when Scan is enabled.
