INTRODUCTION

This manual describes the opera-

tion of the M-PA Voice Guard

Scan model radio. This full-featured portable radio provides Voice Guard two-way communications using the VGE algorithm. The M-PA Voice Guard radio provides full-range performance for private (guarded) and clear communications.

The cryptographic key in the radio provides the encryption and decryption code n ecessar y for private communications. Only radios with the same cryptographic key can monitor and communicate. Cryptographic keys are transferred into the radio using VGE Keyloader, Option V4028. VGE equipped Vo ice Guard radios must also be programmed with identical CUE (Customer Unique Encryption) code(s) before private c ommunications are possible. CUE cod es are programmed into the radio along with the overall person-

ality information using an IBM PC or compatible computer.

Operating controls on the radio include a r ot at able control knob, rotatable volume control, 4-button keypad, pushto-talk, emergency and monitor buttons. The on/off power switch for the unit is located on the removable battery pack.

The 8-digit alphanumeric liquid cr ystal d isplay (LCD ) on the front of the radio displays the operating status of the radio. This backlit display also has twelve status flags that indicate various operating conditions such as private communications enabled, transmitter on, scanning, or emergency mode enabled.

The exact operation of your radio will vary depending upon the mode of operation, the radio’ s programming, and the particular radio system. Consult your radio system’s representative for

particular features that are programmed into your radio.

ON/OFF SWITCH

The ON/OFF SWITCH is located on the battery pack. Sliding this switch up will supply power to the radio from the battery pack. An audible click will be heard and th e "ON" indi cat or will be exposed. When the radio is turned on, it will perform a power-up self test and then resume operation on the previous operating channel as displayed in the LCD. Sliding the switch down will turn the radio off

VOLUME CONTROL KNOB

The VOLUME CONTROL K NOB is a rotatable control on the top of the radio used to adjust the receiver’s audio level in the speaker. Rotating this knob in a clockw is e dir e ction will increase the audio level. Counter-clockwise rotation

CONTROL KNOB

The rotatable 16-position CONTROL KNOB located on the top of the radio is pr ogrammed to select the operating cha nnel, mode, or speci fic Channel Guard encode/decode tones. See MODE/CHANNEL/CG SELECTION for details. A stop plate may be installed under the knob to limit the maximum number of positions to less than sixteen (16). It is normally factory installed for fifteen (15) positions. Some radios may be programmed with this knob disabled.

PTT BUTTON

Pressing the PTT BUTTON on the side of the radio will enable the radio’s transmitter. The "TX" status flag in the display will turn on when the radio is

UNIVERSAL DEVICE CONNECTOR

The Universal Device Connector (UDC) is located on the sid e of the radio just above the PTT and MONITOR BUTTONS. This connector provides connections for the external accessories such as a headset, a speak er-m ik e , or an e merge ncy la nyard. When the radio is locked in a vehicular charger/repeater, the UDC provides the audio and control connections between the radio and the vehicul ar c harge r/r epe ater. The UDC is also used by the maintenance personnel when the radio is programmed.

ALERT T ONES

The M-PA uses alert tones or "beeps" to indicate various operating conditions. Alert tones may be enabled or disabled via the menu mode if the "ALERT" feature is programmed. See "ALERT" MENU for details. The alert tones may be disabled when the radio is programmed.

CARRIER CONTROL TIMER

This feature, programmable on a per channel basis, prevents unnecessary channel traffic and radio damage in the event of a "stuck" mic. If the programmed timer times-out during a transmission, the radio will sound an aler t tone and disable the transmission. The beepin g tone will continue until the PTT BUTTON is released. Releasing the PTT BUTTON resets the timer.

CHANNEL BUSY

If the radio is receiving a signal when the PTT BUTTON is pressed, an alert tone will warn the operator that the radio is receiving a carrier and the transmission will not occur. "RX BUSY" is displayed and the alarm is sounded as long as the PTT BUTTON is pressed. This feature is programmable on or off on a per channel basis.

RECEIVE ONLY CHANNEL

If the selected channel is programmed as receive only, the radio will sound a n alert tone if a transmission is attempted. "RX ONLY" is displayed.

VOICE GUARD DISABLED

If the selected channel is programmed for private operation and private transmit mode has been disabled using the PVT button, the radio will sound a low-pitched beep when the PTT button is pressed. This warns the

operator of the clear mode transmission.

RADIO/CHANNEL FAILURE

If the synthesizer is unable to lock correctly on the selected channel, or another radio failure occurs, an alert tone will sound. If incorrect programming is dete cted or the synthesizer fails to lock, the display flashes "NO LOCK" then the selected channel’s name.

Cryptographic keys are transferred into the radio using the Keyloader, Option V4028. Refer to the Keyloader operator’s manual (LBI-31685) for detailed instructions on ho w to lo ad k e ys i nt o t he Ke yloader .

The radio is capable of storing up to seven (7) different cryptographic keys in

its memory. It is programmed for key selection on a channel or per mode basis.

NOTE

4. Press the PWR button on the

Keyloader and waft for the Keyloader to display "MASTER MODE".

Before private messages can be sent or received, one or more cryptographic keys must be transferred into the radio from the Keyloader.

Transferring Keys Into The Radio

The following procedure outlines basic key transferring steps. See LBI31685 for more details.

1. Turn the radio off.

2. Plug the modular connector of

the Keyloader cable into the Ke yloader’s modular jack.

3. Connect the Keyloader cable to the UDC on the radio .

5. Press the TRN button on the Keyloader. If neces sary, s elect a different cryptographic key to be transferred into the radio.

6. Turn the radio on. The display should read "KEY LOAD".

7. Press the EXE button on the Keyloader to transfer the key The Keyloader will display "GOOD 1.x TRANSFER" where “x” is the selec ted cr yptographic key number.

8. Disconnect the cable from the radio’s UDC. A single beep will be heard from the radio’s speaker if the power-up alert tone is enabled. The radio will

change to the selected channel last indicated in the display.

and beep if the power-up alert tone is programmed on.

Key Zero

All cryptographic keys stored in the radio can be zeroed or "dumped" when the radio i s on by s imultaneous ly press ing the ME NU and S CAN buttons for at least one second. When the key(s) have been zeroed, the radio will display "KEY ZERO" and it will emit a series of beeps. CUE codes stored in the radio are not affected. If the cryptographic key(s) are zeroed, one or more keys must be transferred into the radio from the Keyloader before private communications may continue.

RECEIVING A MESSAGE

1. Slide the ON/OFF SWITCH on

the batter y pack to the on position. The radio will initiate and complete the power-up self-test

2. Select the desired operating mode, channel, and/or Channel Guard. See the MODE/ CHAN- NEL/ CG SELECTION for details.

3. Press the MONITOR BUTTON to disable squelch and adjust the VOLUME CONTROL for the approximate desired speaker audio level. Pressing the MONITOR BUTTON may affect Channel Guard and/or Type 99 tone operation if programmed for the selected channel.

4. If the selected channel is programmed for private operation, the radio will automatically switch between clear or private receive operation.

When an encrypted transmission is received, the "PVT" status flag will flash, the receiver will unsquelch, and the Voice Guard mess age will be heard in the speaker. For this to occur, the selected channel must be programmed for private operation, the correct cryptographic key must be loaded into the radio and the correct CUE code must be programmed.

TRANSMITTING A MESSAGE

1. Select the desired mode, chan-

nel, and/or Channel Guard.

2. When private mode is enabled, the "PV T" status flag in the display will turn on. Toggle transmit operation to private or clear, as desired, by pressing the PVT button (when the menu mode is not enabled).

If a clear mode (non-encrypted) transmission is received, the receiver will unsquelch and it will be heard in the speaker. However, if the selected channel is programme d for Channel Guard or Type 99 tone operation, the receiver will not unsquelch unless the c orrect CG or T99 tone is received.

5. Adjust the volume as necessary.

If a channel is not programmed for private mode operation, "VG DISBL" will momentarily show in the displ ay if an attempt is made to enable private transmit mode. It is not possible to operate on this channel in private mode.

If the radio is programmed for forced private ope ration, "FRCD PVT" will momentarily show in the display. If an attempt is made to d isable private transmit

mode. It is not possible to transmit on this channel in clear mode.

If a chann el pr ogrammed for private operation is selected and there is no key in the radio for the selected channel "NO KEY x" (where "x" is the key number) will periodically flash in the display. If a transmission is attempted, "NO KEY x" will show in the display and the radio will emit a series of beeps and will not transmit.

3. Ensure no one is transmitting on the selected channel by pressing the MONITOR BUTTON to disable squ elch or observing the display for the absence of the "BSY" status flag. If the Channel Busy Lockout feature is programmed for the selected channel, the radio will not transmit when the channel is busy.

4. Press and hold the PTT BUTTON. If the selected channel is programmed for private operation and clear transmit mode has been selected, an alert tone (low pitch ed beep) will be heard in the speaker when the PTT BUTTON is pressed as a warning that radio is not in private mode. The "TX" and "BSY" status flags are displayed.

5. Hold the radio approximately three inches from your mouth and speak into the microphone in a normal voice.

6. Release the PTT BUTTON when the transmission is complete. If the transmission exceeds the programmed Carrier Contro l Tim er limit, the radio will unkey and an alert tone will sound.

7. Listen for a reply.

EMERGENCY OPERATION

The radio may be programmed to transmit GE-STAR emerge ncy signa li ng when the EMERGENCY BUTTON is pressed or from a UDC connected lanyard. If the EMERGENCY BUTTON is programmed for GE-STAR emergency activation, press for approximately one (1) sec ond to ac tivate the transmission. If the lanyard is p rogramme d for activation, follow the instructions provided with it. GE-STAR is programmed to transmit in one of the following methods:

•• GE-STAR is transmitted on

predetermined mode and channel regardless of the selected channel. In this case the selected channel is available for voice and the radio will periodically "jump" to the predetermined channel and send the emergency message and then "jump back" to the selected channel for voice operation.

•• GE-STAR is transmitted on the

selected channel. If the channel is changed, the emergency bursts will follow the newly selected channel.

•• Th e radio switches to and stays on a

predetermined mode and channel and GE-STAR is transmitted on that channel. Rotating the CONTROL KNOB will not change channels. Turning the radio off and back on will reset this condition.

•• GE-STAR is sent on the selected

channel an d the radio l ocks onto that channel. Rotating the CONTROL KNOB will not change channels. Turning the radio off and then back on will reset this condition.

SCANNING CHANNELS

The M-PA m ay be programm ed for non-priority scan, dual-priority scan, or scan operation may be disabled. Scan programming options include a keypad entered scan list or a fixed scan list. Pri-

ority scan programming options include a fixed priority-one channel or the selected channel as the priority-one channel.

The radio may be programmed to scan only the channels in the current mode or it may be programmed to scan across modes.

Scan rate will var y depending upon the number of channels on the scan list and whether or not the radio is programmed to scan for Channel Guard. Fewer channels will result in a faster scan rate. All scan functions are retained in memory when the battery pack is removed.

The radio will not scan when the emergency mode is enabled ("EMG" status flag is on).

Adding Channels To And Deleting Channels From The Scan List

If the "SCAN A/D" menu is programmed, channels may be added to and deleted from the scan list of each mode as follows:

1. Select the desired mode and channe l. If the selected channel is currently on the list, the "S" status flag will be on.

2. Press the MENU button until "SCAN A/D" is displayed.

3. Press the SEL button until the desired priority indicator appears: "S" for non-priority "2" for priority-two, "1" for a priorityone, or no indicator to remove the channel from the scan list. If a new priority channel is selected, the previous corresponding priority channel will become a non-priority scan channel. One

of the following messages may be momentarily displayed:

•• “SCAN DIS”- - The radio is not

programmed to scan.

Using Scan

Toggle scan on or off by pressing SCAN. The "SCN" status flag turns on when the radio is scanning.

•• “F IXED P1"- - A priority-one channel

has been p rogrammed into the radio. A new prior ity-one channel c annot be selected.

•• "FIXD LST" - - A fixed scan list is

programmed into the radio. It is not possible to change the list without reprogramming the radio.

4. To add or delete additional channels, repeat steps 2 through 4.

5. Press the EXIT button to return to normal operation.

If programmed for dual-priority scan operation, the priority-one, priority-two and the remaining channels will be scanned. Once a carrier is detected and, if programmed, the correct Channel Guard is decoded, the display will indicate the channel. Sampling of the priority-one and priority-two channels will continue. Should a priority-one or two channel carrier, regardless of Channel Guard, be detected while a non-priority channel is being received, the disp lay name is updated, the applicable status indicator, "1" or "2" lights, and the channel is switched to the priority cha nn el . Sampling of the pr iority -one channel will continue if a message is being received on the priority-two channel.

If progra mmed for non- prior ity scan operation, once a carrier is detected, and if programmed, the correct Channel Guard is decoded, the display will indicate the detected channel. Scanning will stop and the radio will remain on the channel until the carrier ceases. Scanning will then resume with the selected channel’s name displayed.

TELEPHONE INTERCONNECT CALLS

Telephone interconnect calls may be placed on radio channels equipped with this capability. Each channel programmed into the radio may be programmed for tele phone interconnect by enabling it f or DTMF dial operation. One (1) of ten (10) programmed telephone numbers can be s elect ed and a utomatically dialed. Voice transmissions may be encrypted if the channel is programmed for private operation and the operator selects private mo de after the dial sequence is completed.

Communication takes place in a simplex mode. In other words, the PTT BUTTON must be pressed each time you wish to t ransmit and it must be released to receive.

Placing A Call

Ten (10) te lephone numbers can be programmed in the radio for automatic dial operation. Typically, telephone numbers programmed into the radio by the maintenance personal each have a specific name (8 characters maximum) assigned. For example: “OFFICE” or “HOME”. To recall a number and complete a call. proceed as follows:

1. If the "SCN" status flag is on, press SCAN to turn scan off.

2. Select a channel in your radio system that has telephone interconnect capability The radio should be programmed for

OPERA TING TIPS

Antenna location and condition is important when operating a portable radio. O perating the radio in low areas of terrain, under power lines or bridges, inside of a vehicle or 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 insuring that the antenna is vertical. Moving a few yards in another direction or movin g to a higher elevation may also improve communication. Vehicular operation can be aided with the use of an externally mounted antenna.

Battery condition is another important factor in the trouble free operation of a portable radio. Always properly charge the batteries.

Always observe all of the Federal Communication Commission’s rules and regulations.

OPERATING RULES AND

REGULATIONS

Two-way FM radio systems must be operated in accordance with the rules and regul ations of t he Federal Communication s Commission (FCC ). As an operator of two -way radio equipment, you must be thoroughly familiar with the rules that apply to your particular type of radio operation. Following these rules will help eliminate confus ion, assur e the most efficient use of the existing radio channels, and result in a smoothly func tioning radio network.

When using your two-way radio, remember these rules:

1. It is a violation of FCC rules to interrupt any distress or emergency message. As your radio operates in muc h the same way as a telephone "party line", always listen to make sure that the channel is clear and/or ob-

serve the display for the absence of the "BSY" status flag before transmitting. Emergency calls have priority over all other messages. If someone is sending an emergency message such as reporting a fire or asking for help in an accident KEEP OFF THE AIR!

2. The use of profane or obscene language is prohibited by Federal law.

emergency) is a violation of FCC rules. You may send only those messages that are essential for the operation of your business.

6. It is against Federal law to repeat or otherwise make known anything you overhear on your radio. Conversations between others sharing your channel must be regarded as confidential.

CHARGING THE BATTER Y PA CKS

After receiving a new rechargeable batter y pack from the factory, it should be fully charged before placing it into service. This also applies to recharge-

able batte ries that have been stored for long per iods. When the battery pack requires charging t he radio will signal the operator with an alert tone and the “BAT” status flag will turn on.

Chargers are av ailable with nominal charge times of 1 hour (rapid) and 14 hours (s tandard). Combinations include single ( 1) and multi ( 5) position, s tandard and rapid charge units. In addition, the vehicular chargers/repeaters simultaneously charge the battery packs while the radio is operating. For specific instructions refer to the applicable charger Operating Manual.

Figure 5 - Removing Battery Pack

The rechargeable batteries used with the radio can develop a reduced capacity conditi on someti mes cal le d th e “Memor y Effect”. This condition can occur when a battery is continuously charged for long periods or when a regularly performed duty cycle allows the battery to expend only a limited portion of its capacity. The battery pack

may show a severe decrease in its ability to deliver full capacity for an extended period. Any rechargeable battery pack showing signs of reduced capacit y should be retu rned to a qualified service center for inspection.

RECHARGEABLE BATTERY PACK DISPOSAL

The product that 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 battery into the municipal waste stream. Check with your local solid waste officials for details in your area for recycling options or proper disposal. Call Toll Free 1-800-8-BATTERY for information and/or procedures for returning rechargeable batteries in your state.
