Garmin GTX 330 Installation Manual page 5

CAUTION
The GTX 330 lens is coated with a special anti-reflective coating that 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 following table identifies hardware modification (Mod) Levels for the GTX 330 and GTX 330D Mode
S Transponders. Mod Levels are listed with the associated service bulletin number, service bulletin date,
