WARNINGS USE GOOD JUDGEMENT This product is an excellent navigation aid, but does not replace the need for careful orienteering and good judgement. Never rely solely on one device for navigating. USE CARE The Global Positioning System (GPS) is operated by the U.S. Government, which is solely responsible for the accuracy and maintenance of GPS. The accuracy of position fixes can be affected by the periodic adjustments to GPS satellites made by the U.S. Government and is subject to change in acco

Getting Started This section shows you how to use your receiver for the first time and explains: • Accuracy • Battery Installation • Primary Usage • Getting a Fixed Position Receiver Accuracy The satellite constellation that provides the GPS information used by the receiver is maintained by the Department of Defense (DoD). GPS positioning, for general use, provides 25 meter RMS accuracy or better. Since the signals generated by these satellites are publicly accessible, the DoD has introduced er

Proper Handling - Signal Reception Clear View of the Sky. Because the receiver attains information it needs from satellites orbiting the earth, the antenna needs to have a relatively unobstructed view of the sky. This allows the receiver to choose from all satellites currently available. If the view of the sky is poor, (large cliffs or buildings, heavy foliage or other obstructions) the satellite signals can be blocked and the receiver may take longer to compute a position fix. Holding the Rec
