Battery Installation
The GPS II + operates on 4 AA batteries (not included), which are installed at the
base of the unit. These batteries provide up to 24 hours of use.
To install the batteries:
1. Flip up the metal ring at the base of the unit, and turn the ring 90˚ counter clockwise.
2. Install the batteries (Fig. 3), and close the battery compartment door.
3. Lock the door in the closed position by rotating the metal ring 90˚ clockwise.
Battery life varies due to a variety of factors, including temperature and
backlighting. You may find that the battery life varies in different conditions and
that lithium batteries provide longer life in colder conditions.
When replacing the GPS II + ’s batteries, observe the polarity markings
engraved in the plastic case. An internal 10-year lithium battery will retain your
data while you’re changing batteries.
