REFERENCE Alarms The arrival alarm alerts you when you've reached your destination. 'Auto' provides an alert at one minute from your destination. 'On' allows you to define an alarm distance. The CDI alarm warns you when you deviate off course (left or right) beyond the limits that you set. Alarms The alarms page is used to set two alarms on the GPS 12XL: arrival and CDI. The arrival alarm will alert you when you are approaching a waypoint. The arrival alarm has three available settings: • 'Off'- No alarm will occur. • 'On'- The alarm will occur at the user-specified distance from the destination waypoint. • 'Auto'- The alarm will occur at one minute away (based upon current speed, distance & track) from the each waypoint in the active route or from the GOTO destination. Note: When using a route, the arrival alarm will only occur for the final destination waypoint-not any interim waypoints along the route. To set the arrival alarm: 1. Highlight the 'ARRIVAL' field and press . 2. Select 'On', 'Auto' or 'Off', and press . 3. If 'On' is selected, highlight the distance field, press , enter the desired distance and press . The CDI alarm will alert you if your position deviates off course (left or right) beyond the limits specified. To set the CDI alarm: 1. Highlight the 'CDI Alarm' field and press . 2. Select 'On' or 'Off', and press . 3. If 'On' is selected, highlight the distance field, press , enter the desired distance and press . Note: The arrival and CDI alarms both have setting ranges from 0.0 to 9.9 units (statute miles/nautical miles/kilometers). Setting the CDI alarm to its lowest limits may cause false alarms due to the effects of DOD-imposed Selective Availability. Selective Availability can degrade your GPS position by as much as 100 meters. 46
