Specifi cations
Cleaning - The GPSMAP 182C lens is coated with a
special anti-refl ective coating which is very sensitive to skin
oils, waxes and abrasive cleaners. CLEANERS CONTAIN-
ING AMMONIA WILL HARM THE ANTI-REFLECTIVE
COATING. It is very important to clean the lens using an
eyeglass lens cleaner which is specifi ed as safe for anti-
refl ective coatings and a clean, lint-free cloth. Units with a
monochrome display may use the same cleaning method.
The unit’s case is constructed of high quality material and
does not require user maintenance other than cleaning.
Clean the unit housing using a cloth lightly dampened with
a mild detergent solution and then wipe dry. Avoid chemical
cleaners and solvents that may damage plastic components.
Do not apply cleaner to electrical contacts on the back of
the unit.
Storage - Do not store the unit where exposure to tempera-
ture extremes may occur (see left), 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 download-
ing it to a PC (see pg. 64).
