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.

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 DTMF TRANSMISSION
This function allows you to send a pre-programmed DTMF code to
control a repeater, open another transceiver's squelch, etc.
Manual transmission:
Push desired digit keys in sequence while pushing [PTT].
• Pushing [PTT] may not be necessary depending on programming.
Automatic pre-programmed transmission:
q Push the [DTMF] switch to select DTMF autodial mode, then
push [Y] or [Z] to select the desired channel.
w Push the [DTMF] switch once more to send a DTMF code.
D D DTMF RE-DIAL FUNCTION
This function allows you to transmit the last-used DTMF code at the
push of a key.
Push the [DTMF RE-DIAL] switch momentarily to activate the func-
tion.
• The previously transmitted DTMF code is automatically transmit-
ted.
• If no code has been transmitted since turning the power ON, this
function does not activate.
D D EMERGENCY FUNCTION
The emergency function allows you to send your ID quickly and
easily to your Base Station, etc. in case of emergency.
Push and hold the [EMERGENCY] switch for 1 sec. to activate the
emergency function.
• The transceiver selects a pre-programmed channel, then sends
an emergency signal to your Base Station.
• The pre-programmed channel remains selected until a control sig-
nal is received from the Base Station, or power is turned OFF.
