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 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.
Priority Mode B with Scan
With Priority Scan and Channel Scan on, the radio scans until it locks
onto an active channel. The radio continues to sample the priority
channel while listening to the active scan channel.
