24 BK Radio
UNIT-TO-UNIT CALL
P25 Unit IDs allow for Unit-To-Unit calls
when the radio is operating in Digital Mode.
To view the radio’s ID, press and hold the [*]
key while not in Unit-To-Unit Mode. (Unit-
To-Unit Mode is indicated by a phone icon in
the upper right corner of the display).
Channels programmed for analog only
operation will not be able to transmit or
receive Unit-To-Unit calls.
UNIT-TO-UNIT MODE
When the radio is in Unit-To-Unit Mode, all
scanning functions will be disabled. The radio
will receive and transmit on the Ready-to-
Transmit (RTX) channel only. Depending on
programming, the RTX channel can be the
main channel, a held scan or priority channel
if Talkback Scan is enabled, or the Priority 1
channel if TX on PR1 is enabled. To alert the
user that the radio is in Unit-To-Unit Mode, a
beep will periodically sound until the unit is
returned to normal Operating Mode.
If the RTX channel’s Digital Squelch Mode is
set to ‘selective’, the radio will accept group
calls, correctly addressed Unit-To-Unit calls,
and if RX Mode is set to mixed, analog
signals.
When a correctly addressed Unit-To-Unit call
is received, the radio will beep twice. If the
calling unit’s ID matches one of the Call List
IDs, the associated label will be displayed
along with the RX and phone icon.
Otherwise, the numeric ID will be displayed
along with the RX, ID, and phone icon.

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 the radio will
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.
