Conventional Features
5.10 Conventional Mode Scanning
Channel scanning features common to all operating modes are described in Sections 4.12
and 4.13. The following information describes features unique to conventional operation.
and 4.13. The following information describes features unique to conventional operation.
5.10.1 Selecting a Scan List
Conventional systems are programmed with a default scan list that is normally selected by
all channels in that system. However, there is a programmable option to slave a particular
conventional scan list to a zone. This then becomes the default list for all conventional
channels in that zone (it overrides the system programming). This slave feature is
programmed on the Edit Zone screen.

conventional scan list to a zone. This then becomes the default list for all conventional
channels in that zone (it overrides the system programming). This slave feature is
programmed on the Edit Zone screen.
The default scan list (which is to be used by all conventional channels except those
belonging to slaved zones), can be temporarily changed by using the SCAN option switch
or menu parameters. A scan list selected in this manner is retained through radio power
down.

5.10.1.1
Conventional Scan List Select Procedure
The scan list select procedure is as follows:
1 With scanning OFF, press and hold the SCAN option switch until a tone sounds
(scanning is OFF when the rotating is not indicated in the right status display). If
required, turn scanning OFF by briefly pressing this switch. If the SCAN option switch
is pressed while scanning, Nuisance Channel Delete described in Section 4.12.5 is
performed.

2 The currently selected list is then indicated in the display as “SCAN LIST x”, where
“x” is the scan list number. Rotate the Select switch to select the desired list and then
exit this mode by pressing the Select or SCAN option switch.
exit this mode by pressing the Select or SCAN option switch.
5.10.2 Transmitting in Scan Mode
Each conventional scan list can be programmed for one of the following modes. These
modes determine if priority sampling occurs and also the channel on which transmissions
occur while scanning. Refer to the next section for more information on priority sampling.
