OLD-STYLE BK PRIORITY SCAN
The radio can be programmed with one of three priority modes: A, B, or
C. The table below shows how the priority channel and the transmit
channel are selected in each mode.

Priority Mode A
In Priority Mode A, the priority channel is set by the Channel Selector
knob. Priority Mode A is seldom used by itself because the radio
receives and transmits only on the knob-selected channel.
When Scan and Priority Mode A are enabled, scanning occurs until an
active scan channel is found. The radio receives the message while
continuing to check the priority (knob-selected) channel. The display
shows the scan channel.
If the priority channel becomes active during this message, the Priority
indicator illuminates.
The radio changes to the priority channel and holds for the duration of
the message. The display shows the priority channel.
To reply to a message on the priority channel, press the PTT switch and
transmit on the priority channel. Once activity ceases on the priority
channel, the radio returns to Scan operation.
Priority Mode B
With Priority Scan on and Channel Scan off, the radio can receive on the
knob-selected channel while sampling the priority channel. If the priority
channel becomes active, the Priority indicator illuminates. The radio
changes to the priority channel and holds for the duration of the
transmission
To reply to a message on the priority channel, turn the Channel Selector
knob to the priority channel, and then transmit.
With Priority Scan and Channel Scan on, the radio scans until it locks on
to an active channel. The radio continues to sample the priority channel
while listening to the active scan channel. If activity occurs on the priority
channel, the radio overrides the active scan channel, changes to the
priority channel, and holds for the duration of the transmission.
SCAN OPERATION
RECEIVE
Scan operates only while the radio is not transmitting. The radio checks
for signals on channels in the preset scan list, as well as the channel
selected by the Channel Selector knob.
When a signal is detected, scanning stops and the message is received.
The received channel is shown in place of the transmit channel.
Once the signal ends, the radio continues to monitor the channel for the
preset scan delay time before it resumes scanning.
Basic Scan
Press the SCN button to enable Scan (an arrow will appear above the
button).
If Priority Scan is enabled, press the PRI button to turn it off.
The display indicates Scan operation by flashing the SCN annunciator
(alphanumeric mode) or by two flashing bars (numeric mode).
Scan Code Guard Channels
Press the SCN button to enable Scan (an arrow will appear above the
button).
If the CG button has an arrow over it, press the CG button once to turn
Code Guard Disable off.
When a signal is detected, scanning stops while the radio checks for the
proper Code Guard value. If the signal contains the proper Code Guard
value, the radio receives the message. Otherwise, the radio resumes
scanning immediately.
Nuisance Channel Delete
With Channel Scan on and Nuisance Channel Delete enabled, pressing
and holding the SCN button for more than 1 second will temporarily
remove a currently active channel from the scan list. If the radio is
equipped with a keypad microphone, pressing the [CLR] key while Scan
is on will accomplish the same thing. Not all microphones support these
functions. Contact your dealer to determine which features are available
with your microphone and have been enabled in the radio. When the
radio is powered off and back on, the pre-programmed scan list will be
restored.
