20 BK Radio
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 heard 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.

scans until it locks on to an active channel. The radio

scan channel, changes to the priority channel, and
holds for the duration of the transmission.
To reply to a message heard on the priority channel,
