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.
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.
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
