The temperature rating for the GPS V may exceed the usable range ofsome batteries. Alkaline batteries can rupture at high temperatures.2. With optional Garmin GBR 21/23 Beacon Receiver Input.3. Subject to accuracy degradation to 100m 2DRMS under the U.S.DOD-imposed Selective Availability (SA) Program.4. Alkaline batteries lose a significant amount of their capacity as tem-perature decreases. Use Lithium batteries when operating the GPS V inbelow-freezing conditions. Extensive use of bright screen backlightingwill significantly reduce battery life. Low to moderate screen back-lighting can significantly prolong battery life.
