it will not be possible to select a communications chan-
nel, or use emergency and special call. When trunking
is restored, the radio will automatically be returned to
normal operation.
Emergency and Special Call are not operational
during conventional failsoft. Also, the GROUP
control will not operate.
SCAT OPERATION
A SCAT (Single Channel Autonomous Trunking) Sys-
tem operates with the same set of features as a standard
EDACS system. The only significant user change relates
to the BSY indicator. Since only one channel, operating
as both control and working channel, exists in a SCAT
System, the BSY indicator will be ON when the SCAT
channel is in the working channel mode. When the
transmission on the channel is completed, the indicator
turns OFF and indicates the return of SCAT control
channel signaling.
EMERGENCY OPERATION
The radio's ability to declare an emergency, clear an
emergency, remain locked on an emergency system and
group, and the emergency audio and display freeze can
each be enabled or disabled through programming.
When an emergency is declared, scanning will stop and
restarts only after the emergency has been cleared.
