4) Check the PTT signal operation.
q Input 5 to 10 V to pin 2 of the transceiver PC terminal
or pin 7 of the PG-5H D-SUB terminal (CTS).
w Ensure that the transceiver becomes the transmission
state.
5) Check the voice operation.
q Connect the data communications cable (6-pin mini
DIN terminal and pink/ green pin) of the PG-5H
(Interface cable kit) to the DATA terminal on the rear
of the transceiver.
w Input a 1kHz/ 150 mV AF signal from AG to the green
pin of the data communication cable (PKD line).
Confi rm the modulation of 2 to 4 kHz deviation hangs
when transmitting by PTT operation as stated in step
4), above.
e Input a standard modulation signal of -47dBm (MOD:
1kHz, DEV: 3kHz, and AF output: 0.63V/8Ω) from SSG
to the transceiver.
Check that a 1kHz tone of 3 to 15 mV is output from
the pink pin (PR1 line) of the data communication
cable.

Adjustment Mode

This mode is used to replace or readjust IC916 (EEPROM).
In Adjustment Mode, the transceiver can be adjusted using
its panel keys.

■ How to enter the adjustment mode

1. Tu r n t h e t r a n s c e i v e r p o w e r O F F a n d i n s e r t t h e
adjustment jig (W05-0611-00) into the DATA terminal
located on the rear panel of the transceiver.
2. Turn the transceiver power ON while pressing the [CALL]
and [F] keys to enter adjustment mode.
3. The adjustment item "FRQ A" of the Band A frequency
is displayed when entering the adjustment mode.
Note:
• To exit the Adjustment Mode, turn the transceiver power
OFF.
• When the adjustment mode is activated, the transceiver
automatically sets the frequency as shown in "The
frequency that is set to the transceiver" table, on pages
44 to 46.
