ENTERING THE ADJUSTMENT MODE
q
Turn the transceiver’s power OFF.
w
Connect the JIG plug (see illustration below) to [REMOTE] jack on the rear panel.
e
While pushing and holding [P.AMP/ATT] and [TUNE/CALL], turn the transceiver power ON.
NOTE:
Exiting from the adjustment mode when the transceiver's power is OFF.

OPERATING ON THE ADJUSTMENT MODE
• Enter DDS adjustment mode. : Push [F-1 (REF)]
• Enter TX adjustment mode. : Push [F-2 (TX)]
• Enter RX adjustment mode. : Push [F-3 (RX)]
• Store the set value. : Push [F-4 (SET)]
• Adjust the value. : Rotate [DIAL]
CAUTION:
Connect a dummy load to the antenna con-
nectors during the transmitter adjustment,
when the adjustment condition does not re-
quire a test equipment.
