PRIORITY SCAN
The Priority channel must be programmed before Priority
Scan can be used. When using Priority Scan, the transceiver
will automatically change to the Priority channel when a signal
is received on that channel, even if a signal is already being
received on a normal channel.
• The indicator appears when the Priority channel is selected.
SCAN REVERT
The Revert zone and channel is the zone and channel which
the transceiver automatically selects when pressing the PTT
switch during Scan. Your dealer can program your
transceiver with 1 of 6 Scan Revert types:
• Last Called: The last zone and channel on which you received a
call is set as the revert zone and channel.
• Last Used: The last zone and channel to which you responded
is set as the revert zone and channel.
• Selected: The last zone and channel you selected is set as the
revert zone and channel.
• Selected + Talkback: The last zone and channel you selected is
set as the revert zone and channel. However, you can still
transmit on the current channel by pressing the PTT switch.
• Priority: The Priority channel is the revert channel.
• Priority + Talkback: The Priority channel is the revert channel.
However, you can still transmit on the current channel by
pressing the PTT switch.
