Cleaning the Screen
The lens on the screen is coated with a special anti-reflective coating
that is sensitive to skin oils, waxes, and abrasive cleaners. Cleaners
containing ammonia, alcohol, abrasives, or anti-grease detergents
will harm the anti-reflective coating. It is important to clean the lens
using an eyeglass lens cleaner (that is specified as safe for anti-
reflective coatings) and a clean, lint-free cloth.
If you are connected to COM2 for sonar NMEA input, the unit
interface must be set to GARMIN DGPS, Other DGPS (4800
only), or NMEA In/NMEA Out. If connecting to COM1, the unit
