The unit’s lens 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.

The unit 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 wipe and air dry the 

unit before reuse.
