The user has the ability to use two different timers for Emergency mode (Conventional 
system) - one to enable and one to disable emergency mode, preventing accidental 
enabling and disabling of emergency mode. With Emergency Press and Hold enabled, 
emergency mode is enabled when the Button Press/Hold Duration Timer expires. In both 
cases, emergency mode is cancelled when the Emergency Cancel Timer expires. 

A user may program an Emergency Talkgroup. If Emergency is activated, the radio uses 
the Emergency Talkgroup instead of the programmed talkgroup. If Talkgroup Lock is 
programmed, the Emergency Talkgroup has priority.

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.

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.

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.

Currently if the user presses and holds the Scan button, the Scan List Select feature is 
activated.  This function may be disabled on a per-system basis by programming.

The scan list select procedure is as follows:

1 With scanning OFF, press and hold the SCAN option switch until a tone sounds (or use 

menu selection). Scanning is OFF when the rotating   is not indicated in the right
