Press the Individual Call Wait key
(default: short press F2 button)
to turn the call wait option on. The
Call Wait Squelch icon ( ) is
displayed while call wait mode is on.
When the call wait option is on, all
normal group calls will be muted until
the radio receives an individual call.
On digital channels, if an individual
call with matching destination ID is
received, the call will be heard and
the radio will operate in selective
squelch mode. On analog channels, if
a matching 2-tone or 5-tone call is
received, the call will be heard and
the the radio will operate in normal
squelch mode. After the radio is
inactive for the programmed auto
reset delay, the radio will re-enter
individual call wait mode.
While call wait mode is selected,
press the Individual Call Wait key to
switch to normal squelch mode. This
is the default mode of operation on
analog channels. Normal squelch in
digital mode will receive group calls
addressed to any talkgroup and
individual calls addressed to any
destination ID. The Normal Squelch
icon ( ) is displayed while normal
squelch is selected for digital
channels.
On digital channels, press the
Individual Call Wait key again to return to selective squelch mode. This is the default
mode of operation on digital channels. In selective squelch mode the radio will receive
group calls with matching talk group and individual calls with matching destination ID.
