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. 3
