• Priority

• Dual

• User-Selected Channel Guard
• Nuisance Channel Delete
PRIORITY SCAN
Priority Scan enables the radio to receive on
any channel while monitoring for a message
on the designated priority channel(s). The
radio samples each priority channel at a preset
rate (.25-2.0 seconds) regardless of activity on
any other channel. Priority Scan operates only
while the radio is not transmitting and can be
used in combination with scan operation.
When Switch C (Priority) is up, the display
flashes
SCN
. If a message is received on a
priority channel, the Priority Indicator lights,
and the radio receiver locks onto that channel
for the duration of the transmission, unless a
higher priority channel interrupts.
Priority Scan can be used in combination with
Channel Guard with:
•
Switch C (Priority) up
•
The Squelch knob in the Channel Guard
position (fully counterclockwise detent
position) and
•
The Priority Channel(s) programmed with
Channel Guard
If a message is received on a priority channel,
the radio receiver locks on to the priority
channel and checks to see if the proper
Channel Guard value is present. If the signal
contains the proper Channel Guard value, the
radio receives the message. Otherwise, the
radio will re-check the channel every 4
seconds, until the activity on the channel
ceases.

UNIT-TO-UNIT CALLBACK
If Unit-To-Unit callback is enabled, and a
Unit-To-Unit call is received on the Ready-to-
Transmit (RTX) channel, the user may press
PTT before the hold time expires, causing the
radio to enter Unit-To-Unit Mode and transmit
using the received ID as the destination ID. If
the callback timer expires before PTT is
pressed, the radio will return to normal
Operating Mode, but the phone icon will flash
until the
[*]
key is pressed, bringing up the last
active ID.
To exit Unit-To-Unit Mode, press and hold
the
[*]
key.
The callback timer can be cleared by making
the held channel invalid. For instance, if a
scan channel is being held, turn scan off.
PROGRAMMING UNIT-TO-UNIT CALL LIST
Press
[*]
to bring up the last active ID. If the
last active ID was a Call List ID, the ID’s label
will be displayed along with the phone icon.
Otherwise, the ID number will be displayed
along with the phone and ID icon.
Press a number key (0 – 9) to go directly to the
desired Call List ID, or press
[PRI]
repeatedly
to cycle to the label of the ID to be re-
programmed. Press and hold the
[FCN]
key
to enter ID Programming Mode (
PRG
icon
will be illuminated). As in keypad
Programming Mode, normal radio function
will be disabled until ID Programming Mode
is exited.
