Alarms Setup
The GPS 125 Sounder’s alarms setup page is used
to set the three available alarms: the anchor drag alarm,
arrival alarm, and CDI alarm.
The anchor drag alarm will sound if your boat has
moved outside a range measured from a central point
(your position). The arrival alarm sounds 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 way-
point by the defined range.
To set the alarms:
1. Highlight ‘ALARMS SETUP’ and press
F
.
2. Select the desired alarm distance field and press
F
.
3. Enter the distance for the alarm and press
F
.
4. If you would like to change the ‘On/Off’ setting, press
the
F
key and use the
U
or
D
keys to turn
the alarm on or off.
5. Enter a setting and and press
F
.
When setting the anchor drag alarm, remem-
ber that Selective Availability can degrade
your GPS position as much as 100 meters and
may cause false anchor drag alerts.
