2. RADAR OPERATION
2-31
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.
2.22.2 When the alarm is violated…
Any radar target violating the guard zone will flash, the audio alarm sounds, and
the alarm icon appears (red on the color model). Additionally the message
“TARGET ENTERED INTO GUARD1(GUARD2)” or “TARGET LEFT FROM
GUARD1(GUARD2)” is displayed at the bottom of the screen, depending on the
guard zone type. Press the [CLEAR] key to silence the alarm.
