3.11.2 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 channels and the transmit channels
are selected in each mode.

3.11.3 PRIORITY MODE A WITH SCAN
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 Switches B (scan) and C (priority) are up, scanning occurs until an
active scan channel is found. The radio receives the message while
continuing to check the priority channel. The display shows the scan channel.
If the priority channel becomes active during this message, the Priority
Indicator will light. 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 the
radio will transmit on the priority channel. Once activity ceases on the priority
channel, the radio returns to scan operation.
3.11.4 PRIORITY MODE B
With Switch C (priority) up and Switch B (scan) down, the radio can receive
on the knob-selected channel while sampling the priority channel. If the
priority channel becomes active, the Priority Indicator lights up. The radio
changes to the priority channel and holds for the duration of the transmission.
To reply to a message on the priority channel, use the keypad to change
groups if necessary, turn the Channel Knob to select the priority channel, and
then transmit.
3.11.4.1 PRIORITY MODE B WITH SCAN
With Switches B (scan) and C (priority) up, 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.
