Getting Started

Installing the Batteries

The GPS 300 uses two AA alkaline batteries that are installed
at the back of the receiver. To remove the battery cover, turn
the ring of the battery door screw counterclockwise until the
battery cover can be removed.
Insert the new batteries as
shown, being sure to respect the
polarities, and replace the
battery cover.
Replace the screw and turn the
ring clockwise until the battery
door is held in place securely.
You should avoid overtightening
the battery door screw.

Getting Signals from Satellites

Since the GPS 300 receives information from satellites
orbiting the earth, the antenna needs to have a relatively
unobstructed view of the sky. Large obstructions such as
buildings, cliffs, and overhangs may interfere with signal
reception causing your GPS 300 to take additional time to
compute your location.
