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). Modifi cations or other applications will void the product warranty.
5
Alkaline batteries lose a signifi cant 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 drastically reduce battery life.
