Maintenance
Preventive maintenance
The NSO-II unit does not contain any field serviceable components, therefore the operator
is required to perform only a very limited amount of preventative maintenance.
It is recommended that you always fit the supplied protective sun cover when the unit is
not in use.
Simple maintenance procedures
Cleaning the display unit
The supplied cleaning cloth should be used to clean the screen, where possible. Use
plenty of water to resolve 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 can't 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 plastics 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 that salt crystallize on the surface, causing
water to leak into the card slot.
Checking the keys on OP40 Remote controller
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 this is in the correct position.
