Battery Installation
The GPS 92 operates on 4 AA alkaline batteries (included),
which are installed at the base of the unit. These batteries 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 temperature and use of screen backlighting.
Lithium batteries will provide longer life in colder conditions. The
GPS 92 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 battery level indicator is cali-
brated for alkaline batteries, and will not be accurate when
using NiCad or lithium batteries (see page 38).
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 compartment door to access the batteries.
2. Install the batteries and close the compartment door. When replacing the GPS 92’s batteries,
observe the polarity markings engraved in the plastic case. (The indicated polarity repre-
sents which end of the battery should be viewable when the compartment door is opened.)
3. Lock the door in the closed position by turning the D-ring 1/4 turn clockwise.
Antenna Installation and Removal
The GPS 92’s detachable antenna can be used directly attached to the unit or detached
and used with the suction cup adapter and extension cable. Be sure to attach the antenna
at a location which provides good visibility to the sky (satellites), but does not interfere
with controls or block your view of instruments. Likewise, observe these precautions
when routing the extension cable. The antenna should be oriented as near vertical as pos-
sible—perpendicular to the ground.
