2. RADAR OPERATION

The equipment then searches for targets inside the guard zone to determine the guard alarm type. If a target is found inside the guard zone the guard zone type becomes an “Outward guard alarm”, and any target exiting, the guard zone will trigger an alarm. If no target is found the guard zone type becomes an “Inward guard alarm”, and any targets entering the guard zone will trigger the alarm. The guard alarm type is shown as G1 (G2) IN or G1(G2) OUT.

Note 1: When the radar range is less than the guard zone range, ”G1 (G2) IN” or “G1 (G2) OUT” changes to “G1 (G2) ***.” The guard alarm function is not available while this indication appears.

Note 2: If the network radar is set to standby while the guard alarm is active, the guard alarm is cancelled. The guard alarm is redisplayed when the radar is set to transmit again.
