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.
If a sun cover is available, it is recommended that you always fit it when the unit is not in use.
Cleaning the display unit
A proper cleaning cloth should be used to clean the screen, where possible. Use plenty of
water to dissolve and take away salt remains. Crystalized salt may scratch the coating if using
a damp cloth. Apply minimal pressure to the screen.
Where marks on the screen cannot be removed by the cloth alone, use a 50/50 mixture of
warm water and isopropyl alcohol to clean the screen. Avoid any contact with solvents
(acetone, mineral turpentine, etc.), or ammonia based cleaning products, as they may
damage the anti-glare layer or plastic bezel.
To prevent UV damage to the plastic bezel, it is recommended that the sun cover be fitted
when the unit is not in use for an extended period.
Cleaning the media port door
Clean the media port door regularly to avoid salt crystallization on the surface, causing water
to leak into the card slot.
Checking the keys
Make sure that no keys are stuck in the down position. If one is stuck, wiggle the key to free it
back to normal.
Checking the connectors
The connectors should be checked by visual inspection only.
Push the connector plugs into the connector. If the connector plugs are equipped with a
lock, ensure that it is in the correct position.
