Unit Care
Cleaning -
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.
The 172C has an anti-reflective coating on the lens that can
be damaged by ammonia based cleaners.
When cleaning
the lens use a soft lint free cloth.
Don’t apply the cleaner
directly to the lens, apply a small amount of cleaner to the
cloth and then wipe the lens.
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. is 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. 72).
Water Immersion
-The GPSMAP 172/172C 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 data card and dry the compart-
ments before reuse.
To resolve problems that cannot be remedied using this
guide, contact Garmin Customer Support in the U.S.A. at
800-800-1020 or Garmin Europe at 44/0870.8501241
