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 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 lights up
illuminates. The radio changes to the priority channel
and holds for the duration of the transmission
