2. RADAR OPERATION
2-23
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 in red. 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.
2.22.3 Cancelling the guard alarm

2.23 Watchman
2.23.1 How watchman works
The watchman function periodically transmits radar pulses for one minute to check for
targets in a guard zone. If a target is found in the zone, watchman is cancelled, the audio
alarm sounds and the radar continues transmitting. If no target is found the radar goes into
standby for the number of minutes specified on the RADAR DISPLAY SETUP menu. This
feature is useful when you do not need the radar’s function continuously but want to be
alerted to radar targets in a specific area. “WTCH” appears at the top left corner when
Watchman is active.
