[IN USE] LEDs.
2. Change the Mode
Press and hold the [HANDSET LOCATOR] key for about 2 sec-
onds to change the mode like Mode 1, Mode 2, Mode 3, Mode 4,
Mode 1....
Mode 1:
[CHARGE] LED : Lights up.
Function : Change the channel.
Operation : Each time the [HANDSET LOCATOR] key
is pressed momentarily, change the channel
like 0, 1, 2...9, 0... (default channel is 5ch)
Mode 2:
[CHARGE] LED : Goes off.
Function : Toggle TX power.
Operation : Each time the [HANDSET LOCATOR] key
is pressed momentarily, change over ON/
OFF. (default status is ON)
Mode 3:
[CHARGE] LED : Lights up.
Function : Not used in servicing.
Mode 4:
[CHARGE] LED : Goes off.
Function : Transmit the tone signal for 3 seconds.
Operation : Press the [HANDSET LOCATOR] key mo-
mentarily to transmit the tone signal, and
blinks the [CHARGE] LED.
Each time transmit it, then change the fre-
quency of signal tone like 697 Hz, 770 Hz,
852 Hz, 941 Hz, 1209 Hz, 1336 Hz, 1477
Hz, 1633 Hz, 697 Hz... (default frequency is
697 Hz)
3. Exiting theTest Mode

2. When enter the test mode, the happy tone is emitted.
2. Key Functions
[CHANNEL] key
• Change the channel. (Each time the [CHANNEL] key is
pressed, change the channel like 0, 1, 2...9, 0... (default chan-
nel is 5))
• Refresh PLL, RX/TX counters.
[PGM] key
• Toggle TX power. (ON: lights up the [TALK/BATT LOW]
LED)
• Refresh PLL, TX counters.
[SPEED DIAL] key
• Toggle RX power.
• Refresh PLL REF, RX/TX counters.
[REDIAL] key
• Toggle TX attenuator.
• Refresh PLL status register.
[TALK] key
• Change PLL gain mode. (lowest →highest (4 steps))
[OFF] key
• Exit the test mode and emit the sad tone.
Note: All keys pressed will emit the key tone.

Vdc.
2. TX Loop Voltage Confirmation
1. Connect the digital voltmeter to TP14 (TX LOOPVOLTAGE)
on the BASE MAIN board.
2. Confirm that the value of digital voltmeter is 0.5 Vdc to 4.3
Vdc.
3. TX Frequency Adjustment
1. Connect the RF generator to TP (ANT) on the BASE RF board.
2. Adjust C15 on the BASE MAIN board for 903.8 MHz ± 3
kHz reading on the RF generator.
4. Quad-Voltage Adjustment
1. Connect the digital voltmeter to TP16 (RX AUDIO) on the
BASE MAIN board.
2. Adjust C99 on the BASE RF board for 1.775 ± 0.15Vdc read-
ing on the digital voltmeter.
5. DEMOD Audio Level Adjustment
1. Connect the RF generator to TP (ANT) on the BASE RF board.
2. Connect the audio generator (to feedback bridge) to LINE jack
(J7) on the BASE MAIN board.
3. Set the RF generator as follows.
output frequency : 926.55 MHz
output level : –50 dBm
FM deviation : 25 kHz
MOD tone frequency: 1 kHz
4. Adjust VR1 on the BASE MAIN board for –10 ± 1 dBv read-
ing on the audio generator.
0 dBm = 0.775 V
0 dBv = 1 V
