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 trans-
ceiver has 2 conditions for receive standby:
Audible condition:
This condition mutes audio ONLY when
no carrier is present. You can receive (or
monitor) any signals on a channel.
• Push and hold the [Moni], switch to se-
lect the audible condition.
Any audio mute functions are cancelled
while pushing the [Moni] switch.
Inaudible condition:
This condition mutes ALL signals except
those directed to you. Therefore you
should check a channel’s condition (busy
or not) with the monitor function before
transmitting.
• Push the [Moni] switch momentarily to
select the inaudible condition.

TALK AROUND
The talk around function changes duplex channels to simplex chan-
nels.
• Duplex allows you to contact your base station, repeaters, etc.
• Simplex allows you to contact other portable transceivers directly
(portable-to-portable contact).
Push the [Talk Around] switch one or more times to toggle the func-
tion ON and OFF.
All signals are
received
Only signals con-
taining the proper
tone are received
