4 The temperature rating for the eTrex Legend 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 3VDC voltage regulator. Modifi cations or other
applications will void the product warranty.

Alkaline batteries lose a signifi cant amount of their capacity as temperature decreases. Use lithium
batteries when operating the eTrex Legend in below-freezing conditions. Extensive use of screen
backlighting will signifi cantly reduce battery life.
