Subject to accuracy degradation to 100m 2DRMS under the U.S. DOD-imposed Selective Availability

program.

The temperature rating for the eTrex 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.

Alkaline batteries lose a significant amount of their capacity as temperature decreases. Use lithium

batteries when operating the eTrex in below-freezing conditions. Extensive use of screen backlighting

will significantly reduce battery life.
