the new channel in the emergency mode.

With analog calls, subsequent presses of the PTT switch cause the DTMF emergency
ID to be sent according to the ANI programming (if DTMF ANI is enabled on the
channel). With digital calls, the calls continue to have the emergency bit set.

6.10 Conventional Mode Scanning
Channel scanning features common to all operating modes are described in Sections 5.12
and 5.13. The following information describes features unique to conventional operation.
6.10.1 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.
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.
A scan list selected in this manner is retained through radio power down.
6.10.1.1 Conventional Scan List Select Procedure
The scan list select procedure is as follows:
1 With scanning OFF, press and hold the S CAN option switch until a tone sounds (or use
menu selection). 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 5.12.5 is performed.
