2. RADAR OPERATION
2-31
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, the audio
alarm sounds and the alarm icon appears. Press the [CLEAR] key to
silence the alarm. Press the [ALARM] key and the message
“GUARD1(2) IS OUTSIDE RADAR RANGE” appears. Reselect
appropriate range.
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.
Note 3: If the network radar is set to standby while the radar picture is not
displayed, the audio alarm sounds. Press the [ALARM] key and the
message “STBY MODE HAS BEEN SELECTED. GUARD/WTCHMN
CANCELED.” or “GUARD/WATCHMAN CANCELED. STBY/TX
SELECTED.” appears.
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. Additionally the message “TARGET ENTERED INTO
GUARD1(GUARD2)” or “TARGET LEFT FROM GUARD1(GUARD2)” is
displayed at the bottom of the screen. Press the [CLEAR] key to silence the
alarm. When this is done, “G1(G2) ACK” replaces G1(G2) IN(OUT) at the top
right corner of the display. This means the alarm is temporarily deactivated. To
reactivate the alarm, press the SET GUARD1 or SET GUARD2 soft key as
appropriate.
