Specifi cations subject to change without notice.
1. The temperature rating of the eTrex Vista C may exceed the usable range of some bat-
teries. Some batteries can rupture at high temperatures.
2. Can be subject to accuracy degradation to 100m 2DRMS under the U.S. DoD imposed
Selective Availability (SA) Program when in effect.
3. Alkaline batteries lose a signifi cant amount of their capacity as the temperature decreases.
Use Lithium batteries when operating the eTrex Vista C in below-freezing conditions.
Extensive use of screen backlighting, electronic compass and audible tones signifi cantly
reduce battery life.
