Specifi cations subject to change without notice.
1. The temperature rating for the GPS V may exceed the usable range of
some 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 signifi cant amount of their capacity as tem-
perature decreases. Use Lithium batteries when operating the GPS V in
below-freezing conditions. Extensive use of bright screen backlighting
will signifi cantly reduce battery life. Low to moderate screen back-
lighting can signifi cantly prolong battery life.
