REPEATER OPERATION
Note:
Please consult your dealer for programming the repeater. Due
to the frequency stability on the 6.25 kHz bandwidth channel, when
operating the repeater using an optional OCXO unit, allow the unit to
warm up for 24 hours after turning the power on.
After turning on the power, wait for approximately 10 seconds for
the VCXO or 5 minutes for the OCXO (when mounting) to warm up.
During this time, the CH/STATUS Display will blink. The keys will
function when they are pressed.
When power is applied to the unit, the POWER indicator lights
green. Turn the VOLUME control clockwise until a click sounds, to
unmute the audio. Rotate to adjust the audio. Turn the VOLUME
control counterclockwise fully to mute the audio.
The BUSY indicator lights green while receiving a signal and the
