the icon stops blinking and remains on the

tuning action will stop, an error tone will sound, and

EMERGENCY
If your transceiver has been programmed with the
Emergency function, you can make emergency calls.
Your dealer can set up the transceiver Emergency
function to be accessed via voice, CW, or selcall.
Refer to the appropriate section below, depending on
how your transceiver has been set up.
Note: The Emergency feature can be set up onto a foot switch,
attached to the AUX terminal, for vehicle use.
1 Press and hold the key programmed as
Emergency.
• Depending on the delay time programmed into your
transceiver, the length of time you must hold the
Emergency key will vary.
• When the transceiver enters Emergency mode, the
transceiver will change to the Emergency channel
and begin transmitting based on how the transceiver
is set up by your dealer. Transmit periods are also
set by your dealer.
• Depending on your transceiver settings, the display
may either remain unchanged when you enter
Emergency mode, or a new display with a
preprogrammed text message will appear.
2 To exit Emergency mode, press and hold the
Emergency key again.
• If the Emergency mode completes the preset
number of cycles, Emergency mode will
automatically end and the transceiver will return to
the channel that was in use before Emergency mode
was entered.
Note:
◆ Your dealer can set a beginning of transmit and end of
transmit tone for the transceiver.
◆ Your dealer can set the transceiver to emit tones and received
signals as normal or mute the speaker during Emergency
operation.
