22 BK Radio
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.
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,
turn the Channel Selector knob to the priority
channel, and then transmit.

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.
To reply to a message on the priority channel,
turn the Channel Selector knob to the priority
channel, and then transmit. Once activity has
ceased on the priority channel, the radio
returns to scan operation.
Priority Mode C
With Switch C (priority) up and Switch B
(scan) down, the radio samples the fixed
priority channel at the preset rate. If activity
occurs on the priority channel, the radio
changes to the priority channel and holds for
the duration of the transmission.
To reply to a message on the priority channel,
press the PTT switch. The radio transmits only
on the priority channel when Switch C (priority)
is up. Once activity has ceased on the priority
channel, the radio returns to the receive
channel on the Channel Selector knob.
Priority Mode C 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
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.
