The transmitter consists of an exciter Q201, PA module U201, auto power control (APC) U202 with Q202 and Q203, directional coupler Z201 and associated components. The local signal input of approximately 0 dBm to the transmitter is provided by the synthesizer to the exciter. An amplifier provides 17 dB of gain to prod uce +17 dBm (50 mW) of driv e level to the PA module. During the receive mode, a band switch diode, D202, attenuates the rece i ve f irst loca l osc illator signal at the exciter input to reduce LO leakage at the antenna connector. T he PA module is a 3-stage amplifier that provides a minimum RF power output of 7.0 watts at a battery voltage of 7.2 VDC. The RF power output is fed through the directional coupler Z201 to the antenna. A shottkey diode D201 converts the detected RF signal in the directional coupler to a DC voltage to feed the auto power control circuitry.

Low Pass Filter

The low pass filter Z101 and impedance matching network, consisting of L121 and C171 are provided to prevent excessive transmitter harmonics during the transmit function.

Tx/Rx Antenna Switch

The Tx/Rx antenna switch, consisting of D101, D102 and associated circuitry, provides the switching of RF output to the antenna and the receive signal to the receiver . During the receive function, the diodes are cut of f, isolating the tra nsmit circuit from the antenna. During the transmit function, +5 volts is supplied to both diodes, turning them on and feeding the RF output from the transmitter PA module through the low pass filters via D101 to the antenna. The RF output is suppressed at the receiver RF front end filter by D102.

Rf Power Control

The DC voltage detected by the directional coupler Z201 is supplied to comparator U202 where it is compared with the power reference voltage PWR_REF. This comparison voltage controls the bias voltage to the PA module by drive transistor Q202, and the output power is stabilized by the auto power control circuitry. PWR_REF is provided by the central processing unit (CPU) from information programmed into the EEPROM. The PWR_REF voltage consists of six reference voltages: low frequency, middle frequency an d h igh fr eque nc y b an d in bo th th e h igh an d low power mode s. This po wer contro l provide s the flat ness of t he RF output under varied temperature, voltage supply and frequency bandwidth conditions.

RECEIVER

The receiver has a dual conversion circuitry consisting of a receiver front end, RF amplif ier Q101, 1st mixer Q102, 1st IF 70 MHz Monolithic Crystal Filter (MCF) Z102 and Z601, IF amplifier/limiter/discriminator U101, 2nd IF 455 kHz ceramic filters Z107, Z104, Z105 a nd c eram ic disc rim inator Z106. Receiver IF selectivity for 25 or 12.5 kHz channel spacing is determined by selecting the 455 kHz ceramic filter Z104 for 25 kHz spa cing or Z10 5 fo r 12 .5 kHz spa cin g.

The demodulated receive audio at the AF OUT port o f U101 is adjusted by Q104, R113 and R114 to produce a constant demodulated audio level input into the Audio Speech Pro cessor (ASP) regardless of th e receiver channel spacing mode, 12.5 or 25 kHz. The receive audio gain controlled by Q104 , R113 and R114 is increased by 6 dB when the receiver is switched from 25 kHz to 12.5 kHz channel spacing. Received audio signals and beep tones are amplified by audio frequency power amplifier U407 to achieve the rated 0.5 W audio output power to speaker SP1.

remove the 1st IF image (F MHz) and other out-of-band spurious responses. Total gain is approximately 8 dB with the first IF image rejection more than 68 dB.

To achieve the required RF bandpass filtering characteristics across the frequency band, the first front end filter is electronically tuned by c hanges in the B AND_SW volta ge which is fed to varactor diode D601-D603. This voltage is generated by the D/A converter U421 from the CPU input. The frequency band is divided into three sub-split bands, one at the low end, one in the middle and one at the upper end of the band. The CPU determines which sub-split the desired receive frequency is in and provides the appropriate digital input to U421 to generate the correct BAND_SW signal for RF passband tuning.

The recei ve signal is applie d to dual gate GaAsFE T mixer Q102 and mixed with the 0 dBm local oscillator injection from the synthesizer section to produce the 70 MHz first IF signal.

70 Hhz Filter

The mixer output is connected to the matching circuit and provided to the four pole 70 MHz MCF Z102. The 70 MHz crystal filter reduces the second IF image response (F kHz) to meet spurious response specification. The output of Z601 is applied to the 2nd mixer in the IF IC U101 through the matching circuitry.

U101 consists of the second mixer, two IF amplifiers/limiters, a quadrature detector and a noise filter amplifie r. The second mixer downconverts the first IF 70 MHz signal to the second IF frequency of 455 kHz. Crystal resonator Y101 and associated components provide a 69.545 MHz second IF local oscillator signal. Y101 operated in the third overtone mode.

-140 MHz) and 1st IF/2 (-35

-910

Short circuit protection for U407 consists of U416 and Q416. When AF P A AMP outputs, SP+ and SP-, are shorted together or shorted to ground, an excessive current will be sourced through transistor Q407 which is the pass transistor that provides bias to U407. This voltage drop across pass transistor Q407 will be compared in differential amplifier U416 and fed to voltage level translator Q416 which sends the excessive current status sta te information to the CPU. The CPU then sends a signal to Q407, turning it off and removing bias from U407. The software in the CPU assumes the short circuit is an intermittent short and resets for the excessive current state approximately six (6) seconds later. If the excessive current state still exists, the CPU again turns Q407 off. After five retries, the CPU assumes the short circuit is not intermittent and keeps Q407 turned off. The short circuit condition must be removed before the radio is turned off and then back on to reset the CPU.

Receiver Front End And Mixer

The receive signal is fed from the antenna to a bandpass filter, a RF amplifier and an additional bandpass filter to

The second mixer output is applied to the 455 kHz ceramic filter Z107 and then to the first IF amplifier/limiter. The first IF amplifier/limiter output is provide to either 455 kHz ceramic filter Z104 (for 25 kHz channel space mode) or Z105 (for 12.5 kHz channel space mode). These filters are switched by analog sw itches U102, U 103, U107 and U10 8 depending on th e desired channel spacing mo de. Ceramic discrimina tor Z 106 and i nte rnal qua drat ure de tec tor pro vi de the demodulated audio output signal at AF OUT. The demodulated audio signal, filtered with an internal low pass

filter (fc ≅47 kHz) is then routed to the baseband audio signal processor U401 and a noise squelch circuit.

The noise squelch circuit consists of slow and fast squelch time constants and an additional high pass filter (fc ≅4.0

kHz). The slo w squ elch tim e cons tant i s around 70 ms and is provided to U40 4-2. The fas t squelch time c onstant is ar ound 8 ms and is p rovided t o U404-3. Dur ing scanni ng mode, only the fast squelch is monitored by the CPU. In all other modes, the slow squelch is monitored.

Synthesizer

The synthesizer circuit generates all transmit and re ce ive RF frequencies. This circuit consists of synthesizer IC U302, temperature compensated crystal oscillator (TCXO) U303, voltage controlled oscillator (VCO) U301 and associated loop filter circuitry.

The VCO operates at the transmitter frequency during transmit function and 70 MHz below the receive frequency during the recei v e fu nction . The synt hesi zer is cont rolled by the CPU. Frequency stability is maintained by the TCXO module.

A portion of the VCO output is applied to the synthesizer IC and divided by 65/64 dual modulus prescaler, which is set by pulse swallow counter A and programmable counter B to provide a 6.25 kHz output for comparison with a reference signal. The reference signal is derived from the

12.8 MHz TCXO module. The synthesizer IC divides the

12.8 MHz signal down to the 6.25 kHz signal. (The KPC300/400 PC Programming Software will only permit synthesis of transmit or receive frequencies that are integer multiples of 6.25 kHz. Other frequencies cannot be input into the radio’s personality.) An unlock detector is used to prevent transmission when the freq uency synthesizer is un locked.

Audio modulation from the Audio Signal Processor (ASP) IC U401 is applied to the VCO modulation input via amplifier U402 and the TCXO modulation input via amplifier U403. Th e g ai n of U402 is adjusted de pendent upon the channel spacing mode of the radio. In the 25 kHz channel space mode, U418 is open-circuited, removing R453 from being in parallel with R411. In the 12.5 kHz channel space mode, U418 is short-circuited, placing R453 in parallel with R411 and reducing the transmitter audio gain by a factor of two. (This esta blish es t he 5 kHz ma xim um fr eque nc y d e viation for 25 kHz chan nel spacin g and the 2. 5 kHz maximu m frequency deviation for 12.5 kHz channel spacing.) VR403 and VR402 are adjustable to provide a constant modulation flatness for voice audio and Channel Guard (CG) and Digital Channel Guard (DCG) sub-audible mo dulation.

MOSFET transistor Q316 is turned on during the transmit mode to change the loop gain in order to get lower modulation frequency response. A ripple filter, consisting of Q312, C312 and R331, provides a filtered 4.7 VDC to the VCO to improve the p hase noise characteri stic of the rece iver local injection signal for enhanced receiver pe rf or mance for adjacent channel selectivity, intermodulation and FM hum and noise.

Audio Logic

The audio logic se ction consists of CPU U404, Audio Signal Processor (ASP) IC U401, EEPROM U406 and associated components. The CPU controls all radio operations. The EEPROM contains the personality data and the alignment data.

CPU

The CPU contains the LCD controller, LED controls, 32k bytes of R OM, 1k byte of RAM, a n 8-chann el A/D con v erter and a 2-channel D/A converter. The CPU generates DTMF tones, alert tones, beep tones, GE-STAR (ANI) codes and Digital Channel Guard (DCG) encode codewords. The DCG encode codeword from the CPU is applied to a low pass filter in the ASP IC U401 and summed with the voice signal at U402. Received DCG codewords and T ype 99 tones from the ASP U401 are supplied an d deco ded by the CPU .

AUDIO SIGNAL PROCESSOR U401

The ASP IC U401 contains the CG encoder and decoder, pre-emphasis audio shaping filters, de-emphasis audio shaping filters, limiter, post-limiter filter (i.e., splatter filter) and various Switched Capacitor Filters (SCF). U401 generates CG tones controlled by the CPU. CG and DCG sub-audible modulation signals are summed with the voice audio signal at op-amp U402 and supplied to the VCO and TCXO modulation inputs.

The demodulated audio signal from IF IC U101 can provide voice signal information, CG tones, DCG codewords and Type 99 two-tone sequential information. CG tones are filtered by a tone filter and decoded in the ASP. DCG codewords are filtered by the tone filter and input to multiplexer U417. T ype 99 tones are filtered by a bandpass filter and also input to U417. Multiplexer U417 selects either the DCG or Type 99 signals, outputs the signal to a comparator to “square” the signal to a TTL level digital w ave form and then sends the digitized signal to the CPU for detection.

Before the transmit voice audio signal is input to the ASP , it can be optionally mixed with DTMF or GE-STAR (ANI) encode signals. These ba seband signa ls are p re-empha sized, bandpass filtered, hard limited, run through a post-limiter filter (splatter filte r) a nd then summed at op-a mp U402 with CG tones or DCG codewords.

CLOCK SHIFT

The CPU uses a n ominal 7.3728 MH z clock frequency, which is divided down to 3.6864 MHz to become the clock frequency input provided to the ASP IC U401. Harmonics of this clock frequency can potentially interfere with the performance of the transmitter and receiver , producing self-quieting “beat” notes at specific receiver frequencies or producing an audio whine at specific transmitter frequencies. A clock shift can be programmed for each channel’s receive and/or transmit frequency to move the potentially interfering harmonics of the micr oprocessor cl ock frequency. The microprocessor clock frequenc y is shifted more than +100 ppm, effectively moving potentially interfering clock harmonics off-channel.

POWER SUPPLY

The battery voltage, provided by six nickel cadmium cells, is a nominal 7.5 volts. This voltage is provided to the series regulators via a 4 amp fuse F401. The regulated supply provides +5 volts for the logic section, the analog section, receiver and transmitter sections. The +5.5 v olts f or the PLL frequency synthesizer section is also provided.

RADIO PROGRAMMING

PC PROGRAMMING

The KPC-300/400 Portable Radio is programmed using an IBM compatible personal computer equipped with a RS232 serial port. Adapter TQ-3370 pro vides the RS-232 se rial interface an d the cable between the PC and the adapter box. Programming Cabl e RPM 113 24 72/1 pr ovides the conn ection from the adapter box to the radio’s Universal Device Connector (UDC). The programming software is AE/LZY 213 761.

• Channel Busy Lock-Out

• Carrier Control Timer (CCT)

• Squelch Tail Elimination (STE)

• Fixed Priority 1 Scan Channel

• Channel Guard Encode/Decode (Tone or Digital)

• Display B acklighting

• Alert Tones

• Eme rgency Chan ne l

• Three (3) Auto-Dial T elephone Numb ers (KPC-400

only)

CHANNEL BUSY LOCK-OUT

If channel busy lock-out has been programmed on the

selected channel, the transmit function will be inhibited when the op erator presses t he PTT button while the radio detects a carrier on the channel unless the carrier is modulated with the corresponding Channel Guard tone or code for that selected channel. The radio will immediately begin transmitting when the carrier disappears. Channel bu sy lockout continues to function if Channel Guard decode is disabled with the MONITOR button. The ch annel-busy feature is programmable on a per-channel basis. Type 99 cannot be programmed on a channel with channel busy lock-out.

CHANNEL GUARD

Channel Guard (CG) provides a means of restricting calls to specific radios through the use of Continuous T one Coded Squelch System (CTCSS) tone frequencies ranging from

67.0 Hz to 210.7 Hz. Digital Channel Guard (DCG) also can provide a means of restricting calls through the use of 83 standard Continuous Digital Coded Squelch System (CDCSS) cod es. Each chan nel may be p rogram med for en code/decode, encode only, decode only or for no CG or DCG. Both tone frequencies and digital codes may be used. The tones and codes are listed in Tables 1 and 2.

SQUELCH TAIL ELIMINATION (STE)

STE is used with tone and Digital Channel Guard to eliminate squelch tails. The STE burst is transmitted when the microphone PTT is released. The receiving radio decodes the burst and mutes the recei ver audio for 250 ms. T his mute time allows the transmission to end and to eliminate the squelch tail. The radio looks for STE on the received signal when the micropho ne is either on or off-hook. S TE is enabled for transmit and/or rece ive through PC prog ra mming .

AUTOMATIC NUMBER IDENTIFICATION (ANI)

Automatic Number Identification is a 320 ms burst of code (GE-STAR) that is generated at the beginning of each transmission to identify the radio unit to the dispatcher. If programmed, a beep is sounded at the end of ANI transmission to indicate when conversation can begin as the microphone is disabled until the ANI transmission is completed.

Systems with CG require that ANI be delayed long enough for the syste m to respond before ANI can be decoded. A programmable delay is provided to meet this requireme nt. For exampl e, a del ay of 350 m s re quire s t he op erat or to wai t for 670 ms after pressing the PTT before conversation can be started. If desired, th e ANI messag e can be progra mmed to be sent at the end of a transmission.

1. Do not use 179.9 Hz or 118.8 Hz in areas served by 60 Hz power distribution systems (or 100.0 Hz or 151.4 Hz in areas supplied with 50 Hz power). Hum modulation of co-channel stations may "false" Channel Guard decoders.

2. Do not use adjacent Channel Guard tone frequencies in systems employing multiple Channel Guard tones. Avoid same-areas co-channel use of adjacent Channel Guard tones whenever possible. As stated in TIA/EIA-603, there is a possibility of decoder falsing.

3. To minimize receiver turn-on time delay, especially in system using Channel Guard repeaters or receiver voting, choose the highest usable Channel Guard tone frequency. Do not use tones below 100 Hz when it is necessary to meet the receiver response time requirements as specified in TIA/EIA-603.

CARRIER CONTROL TIMER

This feature, programmable on a per-channel basis, prevents unnecessary channel traffic and radio damage if the transmit timer limit is exceeded. If the programmed timer times-out during a transmission, the radio will beep and stop transmitting. The beeping tone will continue until the operator releases the PTT button. Releasing the PTT button resets the timer.

TYPE 99 TONE DECODE

The radio is programmable to power-up in either selective (Type 99) or monitor mode for channels programmed for Type 99 decode.

When select ive mode is chosen, t he radio opera tes as a tone and voice receiver and allows only those calls that are tone coded for the radio to be heard. Selecting monitor mode allows all calls with the correct Channel Guard (if programmed) on the channel to be heard.

In either mo de, when a c orrect T99 and Chann el Guard (if programmed and enabled) have been decoded, a series of intermittent beeps will be heard to alert the operator of an incoming call. The PG status flag will blink in the display to indicate that a call has been received. If the selective mode was chosen, the radio switches automatically to monitor mode.

At the end of the message, if selective mode is desired, press and release the MO NIT OR button to reset the Type 99 tone signalling function. The PG status flag will cease blinking.

While in selective mode, the radio can be put in monitor mode by pressing and releasing the PTT. A series of beeps is sounded whle the PTT is pressed to indicate that no transmission has occured and the monitor mode has been selected as indicated by with the blinking of the PG status flag. A second press of the PTT will result in normal transmission.

The radio is programmable to decode any Ericsson or Motorola decode combinations from any one of two T99 tone tables on a per-channel basis. T ransmit and/or r ecei ve Channel Guard can be programmed to any channel with Type 99.

Type 99 receive Channel Guard (if programmed) can be disabled by pressing the MONITOR button for more than three (3) seconds.

NOTE

Resetting Type 99 from monitor to selective mode does not affect Channel Guard switch setting.

If a T ype 99 channel is in the scan list and scan is enabled, Type 99 tones are ignored. Scan nin g is pr ov ide d o n a ca rr ier and Channel Guard basis only.

TELEPHONE INTERCONNECT (DTMF) (KPC-400 ONLY)

The operator may make telephone interconnection calls on radio systems equipped for this option. Specific procedures for placing these calls are determined by the ope rating system.

There are two methods to make telephone interconnect calls. One method uses the top three keys ( to send one of three pre-programmed numbers. The other method is to use the keypad ( the telephone number.

The keypad is not active until the PTT button is pressed. Therefore, the PTT button must be pressed at all times when operating any button on the DTMF keypad. Communications takes place in a simplex mode. You cann ot talk and listen at the same time. The PTT button must be pressed each time you wish to talk and, released when you wish to listen.

SCAN

The scan feature permits monitoring of up to 16 receive channels. The scanne d channe ls can b e any freque ncy wi thin the frequency ba nd limits of the rad io and can be Chann el Guard protected (tone or dig ital).

Any channel can be scanned with or without a priority level. One channel can be programmed for Priority 1 (P1), another for Priority 2 (P2) or any or all remaining channels programmed as Non-Priority (S). The radio can be pre-programmed to permit an operator front panel selectable scan list, a fixed Priority 1 channel or a selected Priority 1 channel using the channel select switch.

Scan Vocabulary

The following terms are frequently used in scan operation descriptio n.

• Simple Scan - describes the condition when scan is

enabled and there i s no activity on any ch annel in the scan list.

• Priority Scan - describes the condition when scan is

enabled and the priority scan channel is sampled during the scanning of the channels on the scan list.

• Channel Guard Scan - describes the condition when

scan is enabled and tone or digital Channel Guard must also be detected before locking on any channel.

• Selected Channel - indicates that this is the last

channel that the operator selected with the channel select switch. This channel is displayed unless sca n is enabled and activity is detected on another channel being scanned.

)

Page 14

AE/LZB 119 1906 R1A

• Receive Channel - indicates the channel that has

been detected and identified with the correct c arrier and Channe l G ua rd (i f en ab led ). Th e r eceive cha nnel number will be shown in the display.

• Scan List - indicates an internal list either pre-pro-

grammed or pro gr amme d fr om th e fr on t p anel that includes each channel status that will be scanned when the scan mode is enabled.

• Non-Scan Channel - indicates a channel that is not

in the scan list and will not be scanned when scan is enabled.

• Non-Priority Channel - indicates that this channel

is on the scan list. Activity on this channel will be interrupted by activity on either the Priority 1 or Priority 2 channel.

• Priority 2 Channel - indicates that this channel is

also on the scan list. Activity on this channel will interrupt any activity on any non-priority channel. However, activity on this channel will be interrupted only by activity on the Priority 1 channel (if on scan list).

• Priority 1 Channel - indicates that this channel is

also on the scan list. Activity on this channel will interrupt and supercede any other channel activity.

• Channel Activity - indicates the presence of a cor-

rect carrier with correct Channel Guard (if programmed).

• Ha ng Time - describes the time i nterval (pre-pro-

grammable) that a channel remains locked to a frequency although no ch annel activity is present. This condition arises after channel activity has stopped or the PTT button has been released.

• Fixed Priority 1 Channel - indicates that the channel

has been pre-programmed as the Priority 1 scan channel and cannot be ch anged by the operator.

• Selected Priority 1 Channel - indicates that the

channel selected by the channel select switch will be the Priority 1 scan channel. The operator can still select the Non-Priority and Priority 2 channels.

Pre-Scan Operation

A scan list must be created before scan operation can be used. The scan list can be created in several ways. The ra dio will not go into the scan mode when no channel are programmed or in a scan list.

• Fixed Programmable - the scan list is pre-pro-

grammed using the PC programming softwaare and cannot be changed by the operator.

• Front Panel Programmable - the scan list is created

by the operator using the front pa nel cont rols.

• Selected Channel Programmable - the operato r cr e-

ates the scan list for all Non-Priority and Priority 2 channels. The Priority 1 channel is selected by the channel select switch. This is also pre-programmable using the PC programming software.

ALERT TONES

Alert tones or “beeps” are sounded when a button is pressed and w hen the oper atin g stat us of t he rad io chan ges. All alert tones may be programmed to be remain off.

Power-up Self-test

Each time the radio is turned on, it will perform power-up self-test. All display segments will turn on, and after succ essful completion of the test, the radio will change to the last operating state (channel, etc.) and sound three (3) or four (4) beeps. Three (3) beeps sound if the radio is operating in the normal (not scan) state. Four (4) beeps will sound if the radio is scanning. The status will be indicated in the LCD. If the radio fails the self-test, no beeps will be sounded.

Carrier Control Timer

Channel Busy Lock-out

If channel busy lock-out has been programmed on the selected channel, the transmit function will be inhibited when the op erator presses t he PTT button while the radio detects a carrier on the channel unless the carrier is modulated with the corresponding Channel Guard tone or code for that selected channel. The radio will immediately begin transmitting when the carrier disappears. Channel bu sy lockout continues to function if Channel Guard decode is disabled with the MONITOR button. The ch annel-busy feature is programmable on a per-chan ne l basis.

Type 99 Alert Tone

The Type 99 alert tone, indicating a receive Type 99 call, may be enabled or disabled by programming. If the programmed tone sequence is detected, the radio will beep two (2) times. If the alert tone is disabled, no alert tone will be present when a Type 99 call is received.

ANI Alert Tone

The Automatic Number Identification (ANI) alert tone beep can be enabled or disabled by programming. If the alert tone is enabled, a beep will sound after the PTT is pressed to indicate to the operator to begin voice transmission. Some communication systems require a time delay before voice transmission begins. If the alert tone is disabled, no bee p will sound.

SCAN Alert Tone

The radio will sound a beep when the pressed.

AE/LZB 119 1906 R1A

Priority-One (P1) Scan

If the Priority 1 alert tone is enabled by programming and the radio r eceives a signal on th e Priority 1 chan nel when scanning, the radio will sound a beep.

Radio/Channel Failure

The simultaneous flashing of the LCD display and the sounding of beeps indicates the synthesizer is unable to correctly lock on the selected channel. At this time the radio changes to a mute condition and no audio is heard from the speaker when receiving and the transmit is inhibited if the PTT button is pressed. Select another channel, change the battery pack or have the radio repaired.

SCAN OPERATING MODES

Simple SCAN

Once SCAN is activate d, the ra dio will perform a Sim ple SCAN routine. This routine is performed when there is no activity on any of the channels that are in the Scan list.

The scanning list at right, is an example of the routine performed when there are more than four (4) channels in the Scan list.

(The abbreviation "np" indic ates a non-prior ity channel, and P1 and P2 indicate Priority 1 and Priority 2, respectively.)

The scanning list at right, is an example of the routine performed when there are less than four (4) channels in the Scan list.

The above scanning orders assume that Priority 1 and Priority 2 channels exist. If they have not been assigned, their positions in the scanning order are eliminated.

np3...np2...np1...P1...P2...n p3...np2...np1...P1...P2, etc.

NOTE

Priority channels will continue being scanned during hang time.

PTT Pressing the PTT switch causes the ra-

dio to transmit on the selected channel frequency an d to stop the sc anning routine. A programmable hang time (0.3 to 5.0 seconds) will start as soon as the PTT switch is released. Scanning will resume at the end of the hang time. The hang time is a PC prog rammable option and can be enabled or disabled.

Channel Change Any channel change will change the

selected channel and show it in the display window. A channel change will also stop the scanning routine for a fixed, 2-second hang time. If no activity is detected on this new selected channel during this 2-second hang time, scanning will resume.

Priority SCAN

As soon as any activity is detected on a channe l, the radio will change the scanning mode from Simple SCAN to Priority SCAN. The new receive channel will appe ar in the LCD window.

If the receive channel is a Non-Priority channel, both Priority 1 and Priority 2 channels will be sampled (scanned) every 500 milli-seconds in the order indicated at the right.

• If a Priority 1 channel has not been established, the

radio will only break away to sample the Priority 2 channel every 1.0 second.

• If a Priority 1 channel has been established but not

a Priority 2 channel, the radio will break away to sample the Priority 1 channel every 500 milliseconds.

• If neither a Priority 1 or Priority 2 channel has been

established, the radio will lock on this channel until activity on this channel goes away.

• When the receive channel is a Priority 2 channel,

the radio only samples Priority 1 channel every 500 milliseconds.

• When the receive channel is a Priority 1 channel, no

other channels will be scanned.

P1...P1...P2...P1...P1...P2.. .P1...P1...P2, etc.

Page 16

AE/LZB 119 1906 R1A

Once activity on t he receive channel has ended, a programmable hang time (0.3 to 5.0 seconds) is started. Scanning will resume at the end of the hang time if there is no activity on that channel. The selected channel will appear now on the display . Note that Priority channels will continue being scanned during hang time.

To alert the operator of an incoming call on the Priority 1 channel, an option is available to sound a beep upon receiving this Priority 1 channel.

Scanning for Channel Guard

The scanning for Channel Guard option may be selected if, in addition to carrier activity alone, a correct Channel Guard is also required to lock on a channel when scanning. This option is selected on an individual radio basis.

Scanning Priority channels with the wrong Channel Guard will change the scanning rate as follows:

Priority 1 with wrong Channel Guard: The radio will change its Priority 1 sample rate from 0.5 seconds (.5 seconds) to 2.5 seconds, but it will still sample the Priority 2 channel every 1.0 second.

Priority 2 with wrong Channel guard: The radio will change its Priority 2 sample rate from 1.0 second to 5.0 seconds, but will continue to sample the Priority 1 channel every 500 milliseconds (.5 seconds).

PTT The operator has two PC programma-

ble options to select from in regard to what channel to transmit on. The operator can choose to transmit on the selected channel or on the receive channel. The transmit channel will be shown on the display. Releasing the PTT switch will unkey the transmitter and start the programmable hang time (0.3 to 5.0 seconds), if enabled. Scanning will resume again at the end of the hang time unless there is activity on that channe l.

TONE PROGRAMMING

An IBM-compatible person al computer using MS-DOS and a Programmer Interface Box plus the proper programming software is used to program the T ype 99 tones, Channel Guard tones, and Ch annel Guard digi tal code. Th e Programmer Interface Box is connected between the UDC on the side of the radio an d th e b a c k of the perso na l c om pu t er. Refer to Programming Guide for details.

Two sets of Type 99 tones can be programmed in the radio. Any chan nel can be p rogramme d to decode any call or all calls ba sed on an y one of the two tone sets . Indi vidual , group, and super group paging can be used. Motorola formats are also acc ep t ab le.

PG is displayed on the LCD when that channel has been programmed to receive Type 99 calls. Both receive and transmit Channel Guard may also be programmed to any channel with Type 99 tone.

An Intermittent beep is sounded to alert the operator of an incoming Type 99 call.

Upon receiving a call, the radio will open the audio and flash the PG indicator until it is reset by momentarily pressing the MONITOR button.

NOTE

If a Type 99 channel is in the Scan list and SCAN is enabled, Type 99 tones are ignored. Scanning is done on a Carrier and Channel Guard basis only.

The optional Type 99 programming provides individual, group, and super group call decode. The Motorola-formatted, two-tone, sequential signalling schemes can also be decoded.

In Type 99 tone systems, calls will not be heard from the receiver until the proper two tones are detected. When the second ton e is decoded an d recognized as correct, an ale rt tone sounds during the remaining portion of the second tone. The receiver audio path opens and remains open to receive messages until the decoder is reset. The PG indicator will also flash to show a call has been received.

Channel Change Any channel change will change the

selected channel. The receive channel, if any, will stop being displayed/heard and replaced by the new selected channel. The scanning routine is temporarily stopped for a fixed 2 seco nds and will resume again if there is no activity on the selected channel.

NOTE

Priority channels will continue being scanned during hang time.

The radio can be programmed with up to two separate tables of tones. Either the Ericsson Type 99 format or the Motorola format can be assigned to each tone table. The tone decoder (individual, group, and super group for Ericsson format or individual, group, and quick call for the Motorola format) can be enabled individually for each channel. Once enabled, one of the two tone tables can be selected for each channel.

The Group Call format allows communication with all radios in a group. Th e Supe r Grou p Call (in E ricsson Tone systems) or Quick Call (in Motorola tone systems) allows communications between all radios in a system.

TYPE 99 FORMAT

Tone frequencies in the Ericsson tone system fall within

the range of 517.5 to 997.5 Hz.

In the tone format, the first tone can be f rom Tone Group A (for individual or group calls) or from Tone Group C (for super group calls). The second tone may be from Tone Group B (for individual calls) or from Tone Group D (for group or super group calls). The tone format is illustrated as follows.

For example, assume the paging number to be 123; the first digit of the paging number is a "1." Look in Table 3 and read down the column labeled "100’s Digit" to a "1." Read horizontally across the column labeled "10’s Digit." The Tone Group is B. The second digit of the pa gin g numb er is a "2." The tone number is B2. Look in Table 4 and down the column labeled "Tone Designator" to find B2. Read horizontally across the column labeled "Tone Frequency." The first tone frequency is 787. 5 Hz.

To determine the second tone frequency, look in Table 3 and, as before, find the first digit of the paging number ("1").

The second Tone Group is A. The thir d digit of th e paging number is a "3" and the Tone Designator is A3. In Table 4, read down the column labeled "Tone Designator" and find A3. Read horizontally across the column labeled "Tone Frequency." The second tone frequency is 802.5 Hz.

Tone frequencies in the Motorola tone system are within the range of 288.5 to 1433.4 Hz. In the Motorola tone format, the first tone may be one of three tones: A for Individual Call, B for Quick Call, and C for Group Call. The second or final tone is B in all cases.

NOTE

The radio is able to recognize the A, B, and C tones. Individual, Group, and Quick Call formats may be used simultaneously.

The Motorola tone format is illustrated as follows:

For different paging numbers, locate the first digit in the "100’s Digit" column and determine the tone frequencies as described in the example.

Tone D is the diagonal tone used (in Ericsson systems only) when the first and second tone frequencies are the same. The standard frequency f or Tone D is 742.5 Hz, but may be programmed with any tone frequency.

Individual Call

Tables 5 and 7 may also be used to determine the tone frequencies. The first digit of the code determines the tone group used in the code (see Table 5). Then Table 6 is used to determine the actual tone frequencies. For a code of 124, the tone groups used a re sho w n in Table 5. Tone A and T o ne B are both located in Tone Group 1 and Tone B is tone number 4. Refer to the following examples for additional information.

Page 18

AE/LZB 119 1906 R1A

Example 1 - Code 098:

The digit "0" in Table 5 (First Digit of Code) shows the Tone A is in Tone Group 4 and Tone B is in Tone Group 2 (see Table 5).

Tone number 9 in Tone Group 4 is 524.6 Hz.

Tone number 8 in Tone Group 2 is 879.0 Hz. Example 2 - Code 265:

The digit "2" in T able 5 shows that both Tone A and T one B are in Tone Group 2.

Tone number 6 in Tone Group 2 is 788.5 Hz.

Tone number 5 in Tone Group 2 is 746.8 Hz.

Group Call (Quick Call Format)

In Group Call applications, the tone group is determined by Table 7, while the frequency is d etermined by Table 6. Refer to the following examples.

Example 1- Group Call Code 07 (also code 27 and 37):

The digit "0" in Table 7 shows that Tone B is in Tone Group 2 along with 20 to 29 and 30 to 39 . Tone number 7 in Tone Group 2 is 832.5 Hz (see Table 6).

NOTE

Group Call code numbers range from 00 to 99. However, there are several Group Calls with the same Tone B frequency. This limits the total number of Group Calls to

40.

REMOVING THE BATTERY PACK

BATTERY INFORMATION

CHARGE BEFORE USING

Insert the radio into the slot on the charger and ensure that the ON/OFF/VOLUME control is in the OFF position. Connect charger to an AC power source. Charge the battery for the first time at least 14 hours but no longer than 48 hours. Over-charging may reduce battery life.

RECHARGING THE BATTERY

Recharge the battery when you experience difficultity in receiving or sending a message. Also the battery may need recharging when the red TX indicator is blinking.

Chargers are availabl e w i th n om i na l ch arge t im es o f on e to 14 hours. Combinations include single and multipositio n chargers. When ch arging a ba tt ery pa ck th at i s att ache d t o a radio, always turn the radio OFF to ensure a full charge. For specific instructions, refer to the applicable charger Operator’ s Manua l. Charg ing in non- Ericss on equipm ent may l ead to battery damage and void the battery warranty.

Batteries which have been stored (charged or discharged) will generally not be capable of full capacity until the batte ries have been fully cycled two or three times. (Charging the battery in an Ericsson rapid charger and then discharging the battery pack with the radio until low battery is indicated is considered one cycle.)

INSTALLING THE BATTERY PACK

1. Ensure the ON/OFF/VOLUME control knob is in the

OFF (detent) position.

2. Align the battery pack tabs with the battery mounting

plate slots on the back of the radio (see Figure 6).

3. Insert the tabs into the slots, push down and slide the

battery toward the battery latch until the battery latch clicks into place.

1. Ensure the ON/OFF/VOLUME control know is in the OFF (detent) positon.

2. Press the battery release button to release the battery.

OPERATING TIPS

Antenna location and condition is im portant when op erating a portable radio. Operating the radio in low areas or terrain, under power lines or bridges, inside of a vehicle or

Page 22

AE/LZB 119 1906 R1A

in a metal or steel framed building can severely reduce the range of the unit. Mountains and buildings can also reduce the range of the unit.

In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also improve communications. V ehicular operation can be aided with the use of an externally mounted antenna.

Battery condition is another important factor in the trouble free oper ation of a portable rad io. Always prop erly charge the batteries.

EFFICIENT RADIO OPERATION

Hold the portable radio approximately three inches from your mouth and s peak into t he micropho ne at a nor mal vo ice level.

Keep the antenna in a vertical position when receiving or transmitting a message.

Do not hold the antenna when receiving a message and, especially, do

not hold when transmissing a message.

ANTENNA CARE AND REPLACEMENT

Do not use the portable radio with a damaged or missing antenna. A minor burn may result if a damaged antenna comes into contact with the skin. Replace a damaged antenna immediately. A missing antenna could damage your portable radio.

Use only the supplied or approved antenna. Unauthorized antennas, modifications or attachments could damage the radio unit and may violate FCC regulations.

ELECTRONIC DEVICES

RF energy from your portable radio may affect some electronic equipment. Most modern electronic equipment in cars, hospitals, homes, etc. are shielded from RF energy. However, in areas that instruct you to turn off two-way radio equipment, always observe the rules. If in doubt, turn it off.

AIRCRAFT

Always turn off your portable ra dio be fo re bo ar ding any aircraft.

• Use it o n t he ground only with crew permission

• Do not use it in the air

BLASTING AREAS

To avoid interfering with blasting operations, turn your radio OFF when in a "blasting area" or in areas posted "turn off two- way radio". Re mo t e control RF devices are used by some construction crews to set off explosives.

POTENTIALLY EXPLOSIVE ATMOSPHERES

Areas with potentially explosive atmosphere are often, but not always, clearly marked. Th ese may be fueling areas, such as gas stations, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust or metal powders.

Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.

Tu rn OFF your radio when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the radio or its accessories could generate sparks.
