2. RADAR OPERATION

2.22Guard Alarm

The guard alarm allows the operator to set the desired range and bearing for a guard zone. When ships, islands, landmasses, etc. violate the guard zone, an audio alarm sounds and the offending target blinks to call the operator’s attention.

CAUTION

•The alarm should not be relied upon as the sole means for detecting possible collision situations.

•A/C SEA, A/C RAIN and GAIN controls should be properly adjusted to be sure the alarm system does not overlook target echoes.
