MONITOR AUDIBLE FUNCTION
The monitor function allows you to open the transceiver’s
squelch manually to check whether a channel is busy or not.
The transceiver has 2 conditions for receive standby:
Audible condition:
This condition mutes audio ONLY
when no carrier is present. You can re-
ceive (or monitor) any signals on a
channel.
•
Push and hold the [MONI/AUDI], switch to
select the audible condition.
Any audio mute functions are cancelled
while pushing the [MONI/AUDI] switch.
Inaudible condition:
This condition mutes ALL signals ex-
cept those directed to you. Therefore
you should check a channel’s condition
(busy or not) with the monitor function
before transmitting.
•
Push the [MONI/AUDI] switch momentar-
ily to select the inaudible condition.
