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.
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.
