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.
Priority Scan is enabled, 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. 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.
DUAL PRIORITY SCAN
In each group, up to two of the 16 channels can be designated as
priority channels. These two, PR1 and PR2, are periodically tested for
activity, even if a different transmission is being listened to. Activity on
PR2 preempts activity on any of the non-priority channels. Receptions
on PR1 have priority over any other channel in the group, including
PR2.
Either priority channel can be programmed as a fixed channel, tied to
the Channel Selector knob, or programmed OFF. If the radio is
programmed to transmit on the first priority channel, transmissions will
occur on PR1 when operating in Priority Scan Mode.

CHANNEL GROUPS
Radios are separated into groups of 16
channels each. Each group of 16 channels
can be programmed to have an "individual
personality" with its own set of operational
features.
SELECT A GROUP/CHANNEL
Knob positions 1–16 select channels in the group selected by the
keypad:
1.
Press the
GRP
button to display the current group number.
2. Press a number key for the new group number. Only valid group
entries will be accepted.
When changing groups, invalid entries will not be accepted, and
the radio remains in the previously selected group.
3. Press
the
GRP
button again. The radio returns to normal operation
for the new group, and the selected channel is displayed. All
selected scanning and priority functions affect only the channels in
the group you are operating in.
