Battery Installation - Garmin Personal Navigator GPS 48 Owner's Manual & Reference

Battery Installation

The GPS 48 operates on 4 AA alkaline batteries (includ-
ed), which are installed in the base of the unit. These bat-
teries provide up to 24 hours of continuous use.
Rechargeable NiCad or lithium batteries may also be used.
Battery life will vary due to a variety of factors, including
temperatue and use of screen bacdklighting. Lithium batter-
ies will provide longer life in colder conditions. The GPS 48 also features an
internal 10-year lithium battery which retains your data while changing the AA
batteries or when stored with nearly depleted AA batteries
Note: The on-screen bat-
tery level indicator is cali-
brated for alkaline batter-
ies, and will not be accu-
rate when using NiCad or
lithium batteries.
To install the batteries:
1. Flip up the metal D-ring at
the base of the unit, and
turn the ring 1/4 turn
counterclockwise. Open
the comparment door to
access the batteries.
2. Install the batteries and close the comparment door. When replacing the
GPS 48 batteries, observe the polarity markings engraved in the plastic
case. (The indicated polarity represents which end of the battery should
be viewable when the compartment door is opened.)
3. Lock the comparment door in the closed position by turning the D-ring 1/4
turn clockwise.
