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 
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). 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.
