4
The temperature rating for the eTrex Summit 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-
this cable contains a voltage regulator). Modifications or other applications will void the product warranty.
5
Alkaline batteries lose a significant amount of their capacity as temperature decreases. Use lithium
batteries when operating the eTrex Summit in below-freezing conditions. Extensive use of screen
backlighting will significantly reduce battery life.
