When The Alarm Is Violated; Canceling The Guard Alarm - Furuno 1823C-BB Operator's Manual

2. RADAR OPERATION
The equipment then searches for targets inside the guard zone to determine
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 the audio 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
audio 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 is changed to G1 (G2) ***.
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.
