Battery Replacement
The GPS II requires 4 AA alkaline batteries. These batteries will need to be
replaced after up to 15 hours of operation in normal mode or 20 hours of operation
in battery-saver mode. Rechargeable Ni-cad or lithium batteries may also be used.
Note: The battery level indicator is calibrated for alkaline batteries, and will be
inaccurate if Ni-Cad or lithium batteries are used.
To replace batteries:
1. Remove the battery cover by turning the thumb loop at the side of the unit 1/4 turn
counter-clockwise.
2. Remove used batteries and insert new batteries into position. The battery pole you
can still see should match the symbol marked on the case.
3. Close and secure the battery cover by turning the thumb loop 1/4 turn clockwise.
