AirMap 600c GPS Operation Instructions
Installation & Accessories
Power
The AirMap operates from AA batteries or on 3 volts DC using an optional external power cable with a cigarette lighter adapter. If the power cable is used, the AirMap automatically switches to it if the external power is greater than the battery voltage. If the external power fails, the unit automatically switches to the batteries.
NOTE: Some pilots like to keep fresh batteries in their units, even when using the external power. If the power fails, the unit will automatically
switch to the batteries, thus keeping the unit on without interruption.
Warning! With earlier Lowrance Aviation units, some pilots liked to remove the cigarette lighter plug from the adapter cable and splice the exposed wires directly to their dash consoles. However, the AirMap 600 cigarette lighter adapter contains in the plug a voltage regulator to convert 12 volts down to about 3. Without this regulator, connecting your unit to a 12-volt power source will destroy the unit – and this damage will not be covered by your warranty.
