Alarms Setup

The alarms setup page is used to set the three alarms

available on the GPS 48: the anchor drag alarm, arrival

alarm, and CDI alarm.

The anchor drag alarm will alert you if your boat has

moved outside a range measured from a central point

(your position). The arrival alarm will alert you when you

are approaching a waypoint and have reached the user

defined distance. The CDI alarm will alert you when your

track varies from the shortest distance to a waypoint by

the defined range.

Setting the alarm to off, on or auto:

1.Move the highlight to “ALARMS SETUP’ and press

2. Highlight the off/on/auto field for the desired alarm and

press

3. Change to the desired setting and press

Off – No alarm will occur.

On – The alarm will occur at the distance specified

Auto The alarm will occur automatically at a dis-

tance determined by the GPS.

To set the alarms:

1.Move the highlight to “ALARMS SETUP’ and press

2. Select the desired alarm distance field and press

3. Enter the distance for the alarm and press

Note: The arrival and CDI alarms may be set from 0.0

to 9.9 units. The anchor drag alarm may be set up to

9.99 distance units.

When setting the anchor alarm, remember that

Selective Availability can degrade your GPS posi-

tion by as much as 100 meters and may cause

false anchor drag alerts
