GPS CLEANING
The eTrex is constructed of high quality materials and does not require user maintenance other than cleaning.
Clean the unit using a cloth dampened with a mild detergent solution and then wipe dry. Avoid chemical cleaners
and solvents that may damage plastic components.
LENS CLEANING
The eTrex lens is sensitive to skin oils, waxes and abrasive cleaners. It is very important to clean the lens using
an eyeglass lens cleaner and a clean, lint free cloth.
STORAGE
Storing alkaline batteries in the unit for long periods of time is not recommended. In order to reduce the
chance for battery leakage in the battery compartment, remove the batteries when storing the unit for more than
six months.
Do not store the eTrex where prolonged exposure to temperature extremes may occur (such as in the trunk of
a car) as permanent damage may result. User information, such as waypoints, routes, etc. will be retained in the
unit’s memory without the need for external power. It is always a good practice to back up important user data by
manually recording it or downloading it to a PC (transferring it to MapSource).
WATER IMMERSION
The eTrex is waterproof to IEC Standard 60529 IPX7. It can withstand immersion in 1 meter of water for 30
minutes. Prolonged submersion can cause damage to the unit. After submersion, be certain to remove the batter-
ies and dry the compartment before reuse.
Introduction
Maintenance
Remove the batteries from your eTrex if you don’t
expect to use it for several months. Be sure to observe
the proper polarity when inserting the batteries.
Follow the battery manufacturer’s instructions on the
proper care and handling of the batteries.
