Transmitting Digital Unaddressed Calls
A digital unaddressed call is
similar to a group call, except no
talk group is specified (reserved
talk group $FFFF is used). Any
digital radio with matching receive
frequency and NAC should
receive the unaddressed call.
To enter unaddressed call mode,
repeatedly press the
(star)
key until “ENTER TO
UNADDRESSED VOICE CALL?”
is displayed, then press the left
soft key (YES). The radio will now
transmit with reserved talk group
$FFFF. To exit unaddressed call
mode, repeatedly press the
(star) key until “EXIT
UNADDRESSED VOICE CALL?”
is displayed then press the left soft
key (YES).
Unaddressed call
initiation may be
disabled in radio
programming.
