Battery Installation
The GPS 12XL operates on 4 AA batteries (includ-
ed), which are installed at the base of the unit. These
batteries provide up to 12 hours of use.
To install the batteries:
1. Remove the battery cover by turning the thumb
loop at the bottom of the unit 1/4 turn counter-
clockwise.
2. Insert the batteries into position. The battery pole
you can still see should match the symbol (+ or –)
marked on the case.
3. Replace and secure the battery cover by turning
the thumb loop 1/4 turn clockwise.
Battery life varies due to a variety of factors,
including temperature and backlighting. You may
find that lithium batteries provide longer life in colder
conditions.

Remote Antenna
Installation
An optional remote
antenna may be used
with the GPS 12XL.
The remote antenna
will improve the
receiving capabilities
of the unit by magni-
fying weaker signals
which the built-in
antenna may not be
able to use.
The remote
antenna is attached
by plugging it into
the connector on the
back of the unit (see
above).
Contact your
GARMIN dealer for
remote antennas and
accessories.
