Setting GUARD ZONE
The Guard Zone may be a zone completely surrounding the vessel
or a partial trapezoidal zone to monitor targets entering or departing
the specified area.
Targets entering or leaving the guard zone will sound audible and
visible alerts to the operator. In the “IN” alarm mode, an alarm will
sound if a target enter the area. In the “OUT” alarm mode the alarm
will sound if a target leaves the prescribed area. This type of alarm is
useful for monitoring during an anchor watch, when cruising with
other vessels, pair trawling, or towing operation.
An alarm is sounded when any (apparent) target returning an echo
above the noise threshold is detected. If sea clutter, or other incidental
echoes trip the alarm, adjust the gain control and/or the sea clutter to
avoid this false alarming.
