1.19 Target Alarm
The target alarm looks for targets
(ship, landmass, etc.) in the area
you set. Audiovisual alarms are
released when a target enters (or
exits) the alarm area.
CAUTION
· Do not depend on the alarm as the only
means to detect possible collision
situations.
· Adjust the A/C SEA, A/C RAIN and GAIN
controls correctly so that the alarm
system does not miss the target echoes.
