Alarms and Messages The unit uses an on-screen message system to alert you to unit operating characteristics. When a message appears, press MENU to acknowledge the message. Accuracy Alarm-the GPS accuracy has fallen outside of the user-set value. AIS: Dangerous Target-shows the MMSI (Maritime Mobile Service Identity) of the dangerous target. Alarm Clock-the alarm clock has sounded.

Arriving At [Waypoint Name]-you arrived at the destination waypoint. You can Stop Navigation when this message appears. Battery Alarm-battery voltage has fallen below the value entered in the Battery Alarm setup. Battery Voltage Is Too High-too much input voltage-the unit shuts off in 10 seconds. Decrease the input voltage to the maximum voltage allowed (or less) for your chartplotter. Boat Is Not Moving Fast Enough to Calibrate-the boat is not moving fast enough for the speed wheel to provide a valid speed. Can't Read User Card-error reading card; remove and reinsert. Contact your dealer or Garmin Product Support if the problem persists. Can't Read Voltages That High, Limited To Top Of Range-the voltage value in the Battery Alarm setup is higher than the unit can read. Can't Read Voltages That Low, Limited To Bottom Of Range-voltage value in the Battery Alarm setup is lower than the voltage where the unit automatically turns off. Can't Unlock Maps-data on the data card is not unlocked for the unit. Contact your dealer or Garmin Product Support. Can't Write User Card, Card May Be Full-error reading card; remove and reinsert.
