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.
NOTE
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.
