1. Press the Scan option switch to enable scanning.
The currently selected scan list is momentarily
indicated as “Scan x”, where “x” is the list number
(1-3).
2. To select one of the other lists, press the number key
corresponding to the desired list (1-3) and the
selected list is then momentarily displayed as “Scan
x”. The selected scan list is stored in memory and
does not change until this procedure is repeated.
Programming a Scan List
With full keypad (15-key) models, each of the
three scan lists is user programmable if the Scan Edit
option switch is programmed and user programming
of the list is allowed. Otherwise, the channels in these
lists are determined by dealer programming. User scan
list programming is not available with limited keypad
(3-key) models. Proceed as follows to program a scan
list:
1. Make sure all scanning is off (neither the standard
scan “ S ” icon or radio-wide scan icon is
displayed).
2. Press the Scan Edit option switch and then within 2
seconds press the number key corresponding to the
scan list you want to edit (1-3). If a list is not
selected within the allotted time, the last active
conventional standard scan list is automatically
selected. The selected list is indicated as “SCAN x”.
If user programming is disabled on a list, “NO
LIST” is momentarily displayed and it cannot be
edited.
3. Select the channel you want to add or delete using
the and keys. To change zones, press the F1
key and select the new zone.
4. If the selected channel is in the scan list, the box
around “ S ” is indicated in the upper left corner
of the display. To add the channel to the scan list,
press the “1” key, and to delete the channel, press the
“2” key.
NOTE: The priority channel cannot be deleted (see
Section 2.4.12).
5. To exit this mode and save the changes, press the
ENT or CLR key.
Transmitting in Scan Mode
Each conventional scan list can be programmed
for one of the following modes. These modes deter-
mine if priority sampling occurs and also the channel
on which transmissions occur while scanning. Refer to
the next section for more information.
No Priority - No priority channel sampling occurs
when the list is selected. The radio transmits on the
selected channel.
Priority/Tx Priority - Priority sampling occurs and
the priority channel is the one programmed in the
selected scan list. The radio transmits on the priority
channel.
Priority/Tx Selected - Priority sampling occurs and
the priority channel is the one programmed in the
selected scan list. The radio transmits on the selected
channel.
Priority on Selected - The priority channel is always
the selected channel. The radio transmits on the
selected channel.
Talkback - No priority sampling occurs. The radio
transmits on the channel of a call while scanning is
halted. Then once scanning resumes, it transmits on
the selected channel.
2.4.12 PRIORITY CHANNEL SAMPLING
General
The priority channel sampling feature ensures
that when standard scanning, messages on the priority
channel are not missed while listening to a message on
some other channel. The transceiver can be
programmed so that the priority channel is a fixed
channel associated with the current scan list, the
currently selected channel, or not used (see preceding
section). When the selected channel is a priority
channel,
“P” is indicated in the upper right part of the
display.
Priority channel sampling occurs only with Stan-
dard conventional scanning. It does not occur with
Radio Wide scanning, when listening to any type of
SMARTNET/SmartZone call, or when transmitting. A
series of “ticks” may be heard when the priority
