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 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.
