Page 3-14 BK RADIO
To reply to a message on the priority channel, use the keypad to change
groups if necessary, turn the Channel Knob to select the priority channel, and
then transmit.
Once activity has ceased on the priority channel, the radio returns to scan
operation.
3.11.5 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.
3.11.5.1 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.
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 scan
operation.
3.11.6 CHANGE THE PRIORITY 1 CHANNEL
The fixed Priority 1 channel can be permanently set or can be changeable. If
the radio has a changeable priority channel, use the following steps to make
this change:
1. Slide Switches B (scan) and C (priority) down.
2. Use the keypad to change groups, if necessary. Turn the Channel
Selector knob to the channel you want to enter as the new Priority 1
channel.
3. Press the [PRI] key. A short beep sounds and PR appears in the
display, indicating that the displayed channel is now the Priority 1
channel.
NOTE: If the radio is programmed for Dual Priority operation, only the
Priority 1 channel can be changed with the [PRI] key.
NOTE: A channel can be the priority channel even if it is on the Scan
List. Due to multiple sampling of the same channel, however,
maximum performance occurs when the priority channels are not
on the Scan List.
