ALARM" + 'ENTER'

5.5.3 ANCHOR ALARM

This function allows inserting of the limit of anchor dragging: beyond that, the

alarm is activated. The chart plotter computes the distance between the current GPS posi-

tion and the GPS position saved at the activation of the anchor alarm in the menu. If the

computed distance exceeds the value set in the menu, the chart plotter shows the alarm

message and starts the acoustic alarm. The default setting is Off.

'MENU' + "ADVANCED SETTINGS" + 'ENTER' + "ALARMS" + 'ENTER' + "AN-

CHOR ALARM" + 'ENTER'

5.5.4 DEPTH ALARM

transducer) is too shallow. The default setting is Off.

'MENU' + "ADVANCED SETTINGS" + 'ENTER' + "ALARMS" + 'ENTER' +

"DEPTH ALARM" + 'ENTER'

5.5.5 EXTERNAL ALARM

When any alarm condition occurs the pin is switched from High Impedance to

ground. This signal can be used by an external device (as a hooter or buzzer). The default

setting is On.

'MENU' + "ADVANCED SETTINGS" + 'ENTER' + "ALARMS" + 'ENTER' + "EX-

TERNAL ALARM" + 'ENTER'

5.5.6 GROUNDING ALARM (GUARDIAN TECHNOLOGY)

The chart plotter is provided with a function that, by querying the map's data,

verifies potential danger to navigation due to shallow water, land, rocks, obstructions and

shoreline constructions. The maps are scanned periodically (every 10 seconds). When the

Grounding Alarm is active, the chart plotter scans an area in front of the boat. This area is

identified by a triangle drawn in front of the boat icon whose direction is determined by the

current boat heading. The length of the triangle is user selectable and its angle is 30 degrees.

If any of the above objects are found, the chart plotter notifies the danger on a dedicated

warning message box in the Grounding Alarm Report page (see Par. 5.5.9). The Grounding
