PROGRAMMABLE FUNCTIONS
DD
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.
DD
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.
DD
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.
DD
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.
DD
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.
