The temperature rating for the eTrex Vista may exceed the usable range of some batteries. Alkaline
batteries can rupture at high temperatures. External power can only be applied using the GARMIN
Auto Power Adapter (P/N 010-10203-00) or PC Interface Cable with Auto Power Adapter (P/N
010-10268-00). These cables contain a 12 VDC to 3 VDC voltage regulator. Modifi cations or other
applications will void the product warranty.
5
Alkaline batteries lose a signifi cant amount of their capacity as temperature decreases. Use lithium
batteries when operating the eTrex Vista in below-freezing conditions. Extensive use of screen backlight-
ing and the electronic compass will signifi cantly reduce battery life. Different brands of batteries will
vary in performance.
