When systemscan is turned off, group scan is indicated by a dash in
the Groupdisplay (the System display continues to indicate the selected
system).When system scan is occurring, dashes appear in both the
Systemand Group displays even if group scan is not programmed.
Groups canbe locked out of scanning using the LCK key (refer to

There is a Time-Out Timer feature which automatically disables the
transmitterif it is continuously on for longer than the programmed time.

operatorfor a time from 0.5-5.0 minutes. The timer and tone are reset by
releasingthe push-to-talk switch. This timer prevents a blocked channel
caused byan accidentally keyed transmitter and also possible transmitter
damage causedby transmittingfor extended periods.
