3 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 or PC Interface Cable with Auto Power Adapter. These cables contain a 12 Vdc to 3 Vdc voltage
regulator. Modifications or other applications voids the product warranty.
4 Alkaline batteries lose a significant amount of their capacity as temperature decreases. Use lithium batteries
when operating the eTrex Vista in below-freezing conditions. Extensive use of screen backlighting and the
electronic compass significantly reduces battery life. Different brands of batteries vary in performance.
