Watchman
The watchman feature, disabled or enabled
at the main radar, periodically transmits
pulses to check for targets in the guard
zone. For further details, see the Operator’s
Manual for the main radar.
•
The indication “WATCHMAN” appears on
the remote display and main radar when
watchman is active.
•
The indication is shown in white on black
background for two seconds on the
remote display when the [RANGE] key on
the remote display is operated while
Watchman is in standby. (Range
command is not accepted in this case.)
•
Operating any key among GAIN, RANGE
and STC from the remote display while
the watchman is transmitting will
automatically cancel the watchman, and
the radar transmits continuously.
Watchman cannot be canceled from the
remote display when it is in standby.
Guard zone
The guard zone may be independently set.
