  • Page 3: Warning

    WARNING: • The GMR-GPS should be used as an aid in navigation. The unit is not intended to replace basic navigational procedures and common sense. • Because of errors inherent in the nature of the GPS system, the unit will not guide you to an exact position or the precise indicated coordinates.

  • Page 4: General Features

    GPS receivers. As with all other GPS units available to the public, the GMR-GPS makes use of the C/A signals to establish position and altitude. The accuracy of a displayed position varies with a number of factors including time.

  • Page 5: The Gps Receiver

    THE GPS RECEIVER A GPS receiver such as the GMR-GPS uses the C/A signals from the satellites to determine its position on earth. Signals from three satellites are needed to provide an unambiguous position fix, with reliable altitude indications requiring a fourth. In most circumstances, a GPS receiver will be able to receive signals from more than four satellites and can decide which it will use to give the best position.

Battery Charging Contacts: Provide in-unit charging of batteries when unit is placed in charging stand.

  • Page 8: Accessories

    This will ensure optimum performance for the GMR-GPS. Use of the Audiovox charger with other brands of batteries is not recommended, as battery charging times will vary. Refer to the manufacturer’s instructions for charging other brands of batteries.

  • Page 9: Using Rechargeable Batteries Or Vehicle Cigarette Lighter Battery Eliminator

    Using Rechargeable Batteries or Vehicle Cigarette Lighter Battery Elimina- tor: When rechargeable batteries are installed in the GMR-GPS unit, they can be recharged by placing the unit on the optional charging stand, Part Number GMRGPS-SC. CAUTION: The optional charging stand is intended for use only with Audiovox-approved rechargeable (NiMH) batteries (P/N GMRGPS-BT).
