Maintenance
Preventive maintenance
The unit does not contain any field serviceable components. Therefore, the operator is
required to perform only a very limited amount of preventative maintenance.
Sun cover
It is recommended that you always fit the sun cover when the unit is not in use.
Cleaning the display unit
To clean the screen:
• A micro-fiber or a soft cotton cloth should be used to clean the screen. Use plenty of
water to dissolve and take away salt remains. Crystallized salt, sand, dirt, etc. can scratch
the protective coating if using a damp cloth. Use a light fresh water spray then wipe the
unit dry with a micro-fiber or a soft cotton cloth. Do not apply pressure with the cloth.
To clean the housing:
• Use warm water with a dash of liquid dish soap or detergent.
Avoid using abrasive cleaning products or products containing solvents (acetone, mineral
turpentine, etc.), acid, ammonia, or alcohol as they can damage the display and plastic
housing.
Do not:
• use a jet or high pressure wash
Checking the connectors
Push the connector plugs into the connector. If the connector plugs are equipped with a
lock or a position key, ensure that it is in the correct position.
Touchscreen calibration
Use the system setting option to calibrate the touchscreen.
