Technical Specifications - Garmin GPS 400W, GNC 420W Installation Manual

The GPS 400W Series product lens is coated with a special anti-reflective coating which
is very sensitive to skin oils, waxes and abrasive cleaners. CLEANERS CONTAINING
AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING. It is very important
to clean the lens using a clean, lint-free cloth and an eyeglass lens cleaner that is
specified as safe for anti-reflective coatings.
The use of ground-based cellular telephones while aircraft are airborne is prohibited by
FCC rules. Due to potential interference with onboard systems, the use of ground-based
cell phones while the aircraft is on the ground is subject to FAA regulation 14 CFR
§91.21.
FCC regulation 47 CFR §22.925 prohibits airborne operation of ground-based cellular
telephones installed in or carried aboard aircraft. Ground-based cellular telephones must
not be operated while aircraft are off the ground. When any aircraft leaves the ground, all
ground-based cellular telephones on board that aircraft must be turned off. Ground-based
cell phones that are on, even in a monitoring state, can disrupt GPS performance.
