2
Subject to accuracy degradation to 100m 2DRMS under the U.S. DOD-imposed Selective Availability
program.
3
The temperature rating for the eTrex may exceed the usable range of some batteries. Alkaline bat
teries 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 (This cable contains a voltage regula
tor). Modifi cations or other applications will void the product warranty.
4
Alkaline batteries lose a signifi cant amount of their capacity as temperature decreases. Use lithium
batteries when operating the eTrex in below-freezing conditions. Extensive use of screen backlighting
will signifi cantly reduce battery life.
