ment, use the assigned operating frequency.
Caution: Do not transmit from the radio set connected to the
AT-1082/PRC; damage to the equipment may result.
c. On the receive radio set, make the following adjustments:
(1) Set the volume control for maximum signal output.
(2) set the squelch control, if provided, to off.
