In addition to calls on channels in the scan list,
pages, private/unit calls, and telephone calls are
received while scanning. Private and telephone calls
are not interrupted by priority messages.
6.12.2 PRIORITY TALK GROUP SAMPLING
One talk group in the scan list can be designated a
priority talk group by programming or it can be the
selected talk group. When scanning, messages on a
non-priority talk group are interrupted by messages on
the priority talk group. Priority scanning must also be
supported at the system level for it to occur as
programmed in the radio.
6.12.3 SCAN LIST EDITING AND SELECTION
SMARTNET/SmartZone and P25 Trunked scan
lists are user programmable if the
SCN ED
option
switch is programmed. The procedure is described in
Section 4.12.1.
With SMARTNET/SmartZone and P25 trunked
operation, each channel (talk group) can be
programmed to select one of the programmed scan
lists or so scanning is disabled (No List). In addition,
each channel can be programmed so that scanning is
automatically enabled (Auto Scan) when it is selected.
If the
SN LIST
option switch is programmed, the
list that is selected by all talk and announcement
groups in the current system can be temporarily
changed by the user as follows. Also selectable if
desired is “No List” (scanning disabled) or
“Programmed” (default list). The programmed default
list is automatically reselected at power up.
Proceed as follows to temporarily change the
currently selected scan list:
1. With scanning disabled (the rotating
icon is not
indicated in the right status display), press the
SN
LIST
option switch.
2. The currently selected list is displayed as “List x”,
with “x” the currently selected list. To exit without
changing the selected list, simply press the
SN LIST
option switch again.
3. To select another list, “Programmed”, or “No List”,
rotate the Select switch. When the desired list is
displayed, select it and exit this mode by pressing
the Scan List option switch again.
6.13 DYNAMIC REGROUPING
The dynamic regrouping feature allows a
dispatcher to change the current talk group or switch
mobiles to a predefined regrouping channel to receive
an important message. When the console issues a
regroup order, the radio switches to the prepro-
grammed regroup talk group. If the lock mode was not
specified, the selected talk group can be manually
changed and the previous talk group is reselected if
power is cycled. If a locked regroup command is
received, the displayed talk group cannot be changed
manually or by cycling power. It can be changed only
after a clear order is received from the console.
Dynamic regrouping operates as follows:
1. When this command is received, alternating tones
sound and the radio automatically changes to the
regrouping channel and “DYN REGRP” is
displayed.
2. Manually select the channel corresponding to that
tag. If this is not done, transmission still occurs on
the new channel, but the alternating tones sound
each time the PTT switch is pressed.
3. Talk and listen as usual. The dispatcher cancels
dynamic regrouping which is indicated by a short
tone. If a standard channel is not selected after this
occurs, transmission is not allowed if the talk group
is assigned as a dynamic regrouping talk group only.
If it is assigned as a normal talk group, normal trans-
missions are allowed.
