SECTION 4

ELECTRICAL ADJUSTMENTS

• Make the set in test mode. (See page 12)
• Remove the solder of the BP (ANT) on the BASE MAIN board

when performing adjustments. After completing the adjustments,
short the BP (ANT) by solder.

– TX Adjustments –

1. TX Power Adjustment

Setting:

Procedure:
1. Connect a power meter to TP (ANT) and TP (GND) on the

BASE MAIN board.

2. Adjust RT301 on the BASE RF board (the BASE RF board is

mounted on the BASE MAIN board) so that the value of power
meter becomes –6.5 dBm.

2. TX Frequency Adjustment

Setting:

Procedure:
1. Connect a frequency counter to TP (ANT) and TP (GND) on

the BASE MAIN board.

2. Adjust CT1 on the BASE MAIN board so that the value of

frequency counter becomes 926.897468 MHz.

3. Modulation Sensitivity Adjustment

Setting:

Procedure:
1. Connect an AF OSC to the LINE jack (J1) on the BASE MAIN

board.

2. Connect a deviation meter to TP (ANT) and TP (GND) on the

BASE MAIN board.

3. Press the

[2]

key to change the test mode step to TX MOD

CHECK.

4. Adjust RT3 on the BASE MAIN board so that the value of

deviation meter becomes

8 kHz deviation.

0 dBm = 0.775 V, 0 dBV = 1 V

DISCRI Voltage Adjustment

Setting:

Procedure:
1. Connect a SSG to TP (ANT) and TP (GND) on the BASE

MAIN board.

2. Connect a digital voltmeter to TP (DISCRI) and TP (GND) on

the BASE MAIN board.

3. Press the

[4]

key to change the test mode step to RX SENS.

4. Adjust L3 on the BASE MAIN board so that the value of digi-

tal voltmeter becomes 1 V.

2. TEL Out Level Adjustment

Setting:

Procedure:
1. Change the modulation of SSG to 1 kHz,

8 kHz deviation.

2. Connect a noise meter to the LINE jack (J1) on the BASE

MAIN board.

3. Adjust RT2 on the BASE MAIN board so that the value of

noise meter becomes –11.5 dBm.
