1. Make sure that both standard and radio wide scan-
ning are off (the rotating icon is not indicated in
the right status display).
2. Select the channel that you want to be the priority
channel using the Select switch in the normal
manner. If the channel is in a different zone, also
select the appropriate zone.
3. Press the
PRI SEL option switch and “P” is indi-
cated in the left status display as just described to
indicate that the selected channel is now the priority
channel.
4.12 STANDARD CONVENTIONAL CALLS
Standard conventional calls can be placed to other
mobile units monitoring the selected channel. The
proper coded Call Guard squelch tone or code may
need to be transmitted by your transceiver for them to
receive your call (see Section 4.5).
Placing a Standard Conventional Call
1. Turn power on and set the volume as described in
Section 3.1 on page 9. Select the channel
programmed for the mobile you want to call (see
Section 3.6 on page 10).
2. Monitor the channel automatically or manually as
described in Section 4.2 on page 19.
3. Press the PTT switch and the call proceeds as
follows:
• If the Busy Channel Lockout feature is
programmed on the channel, the transmitter is
automatically disabled if the channel is busy (see
Section 4.4).
• Otherwise, busy and out-of-range conditions are
not indicated and speaking can begin after moni-
toring the channel.
4. Press (and hold) the PTT switch to talk and release
it to listen. When the call is finished, place the
microphone back on-hook.
Receiving a Standard Conventional Call
1. Select or scan the channel programmed for the call
you want to receive (refer to Section 4.11 for more
scanning information).
2. When the call is received, take the microphone off-
hook and press the PTT switch to talk and release it
to listen. If scanning, you may have to respond
before scanning resumes to ensure that the response
occurs on the channel of the call.
3. When the call is finished, place the microphone
back on-hook.
4.13 PROJECT 25 MODE FEATURES
4.13.1 VIEWING INDIVIDUAL ID
Each transceiver which operates on Project 25
(digital) channels is assigned an eight-digit individual
ID. This number is unique for each transceiver and can
be any number from 1-16,777,216. When power is
turned on with a Project 25 channel selected, this ID is
briefly displayed.
4.13.2 GROUP IDS
Each Project 25 channel is programmed with a
group ID that determines which group of mobiles will
receive the call. A call is received on a channel if a
selected or scanned channel is programmed with that
group ID and the correct NAC is detected (see
following). Group IDs can be any number from
0-65,535. Group ID detect can be disabled by the
Normal/Selective squelch function described in
Section 4.5.
4.13.3 CODED SQUELCH
Project 25 conventional channels also use a NAC
(Network Access Code) to control which calls are
received on a channel. The NAC can be 0-4095, and
each transmit and receive channel can be programmed
for a different code. Other operation, such as moni-
toring before transmitting, is similar to that of standard
analog channels. NAC (and group ID) detect can be
disabled by the monitor mode described in Section 4.3.
