PROGRAMMABLE FUNCTIONS
D D
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/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 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/AUDI] switch momen-
tarily to select the inaudible condition.
D D
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
function ON and OFF.
