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.
• Enter TX adjustment mode.
• Enter RX adjustment mode.
• Store the set value.
• Adjust the value.
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.
