to prevent the interruptions from making a message
difficult to understand. Times of 0.5-8.0 seconds can
be programmed in 0.5-second steps.
Changing The Priority Channel
If a fixed priority channel is associated with the
current scan list, it can be changed to another channel
if the PRI ED option switch is programmed. With dual
priority, this changes only the first priority channel. To
change both priority channels, use the Scan List Edit
function described in Section 4.12.1. Proceed as
follows to change a priority channel using the PRI ED
option switch:
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 ED option switch and “Priority” is
briefly displayed to indicate that the selected
channel is now the priority channel. Other indica-
tions that may occur are as follows:
• If “No Priority” is displayed, priority sampling
may not be enabled on the scan list.
• If “Sel Chan” is displayed, the priority channel is
always the selected channel and cannot be
changed.
• If no indication displayed, the scan list may not be
user editable or the channel may not be in the scan
list.
5.12 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 or P25
NAC may need to be transmitted by your radio for
them to receive your call (see Sections 5.5 and 5.15.3).
Placing a Standard Conventional Call
1. Turn power on and set the volume as described in
Section 3.1 on page 14. Select the channel
programmed for the mobile you want to call (see
Section 3.4.2 on page 15).
2. Monitor the channel automatically or manually as
described in Section 5.2 on page 26.
3. Press the PTT switch and if the Busy Channel
Lockout feature is programmed on the channel, the
transmitter is automatically disabled if the channel
is busy (see Section 5.4). Otherwise, busy and out-
of-range conditions are not indicated and speaking
can begin after monitoring 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 5.11 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, responses may occur on the
priority, selected, or receive channel as described in
Section 5.11.3.
3. When the call is finished, place the microphone
back on-hook.
5.13 DTMF/ANI SIGNALING
DTMF (Dual Tone Multi-Frequency) tones can
be generated for ANI (Automatic Number Identifica-
tion) and other purposes on conventional analog
channels. One of the following options may be
enabled on each channel:
Pre-Tx ANI - A preprogrammed ANI sequence is
automatically sent each time the PTT switch is
pressed.
Post-Tx ANI - A preprogrammed ANI sequence is
automatically sent each time the PTT switch is
released.
