3 The temperature rating for the eTrex Legend may exceed the usable range of some batteries. Alkaline batter-
ies 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 Legend in below-freezing conditions. Extensive use of screen backlighting and the
electronic compass significantly reduces battery life. Different brands of batteries vary in performance.
