Maintenance

IMPORTANT: It is recommended that the supplied sun cover be installed for protection when the unit is not in service.

Display Screen Cleaning

Routine cleaning of the display screen is recommended to prevent a buildup of salt and other environmental debris. Crystalized
salt can scratch the display coating when using a dry or damp cloth. Ensure that the cloth has a sufficient amount of fresh water
to dissolve and remove salt deposits. Do not apply aggressive pressure on the screen while cleaning.
When water marks cannot be removed with the cloth, mix a 50/50 solution of warm water and isopropyl alcohol to clean the
screen. Do not use acetone, mineral spirits, turpentine type solvents, or ammonia based cleaning products. The use of strong
solvents or detergents may damage the anti‑glare coating, the plastics, or the rubber keys.
It is recommended that the sun cover be installed when the unit is not in use to prevent UV damage to the plastic bezels and
rubber keys.

Media Port Cleaning

The media port door area should be cleaned on a regular basis to prevent a buildup of crystalized salt and other debris.

Stuck Buttons

Verify that there are no buttons stuck in the down position. If a stuck button is found, wiggle the button to free it.
