Preventive maintenance

The unit does not contain any field serviceable components, there-
fore 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.
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 turpen-
tine etc.), Ammonia-based or vinegar-based cleaning products as
they may damage the anti-glare layer, plastics bezel, or rubber keys.
To prevent UV damage to the plastic bezel and rubber keys, it is
recommended that the sun cover be fitted when the unit is not in
use for an extended period.
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 this is in the correct position.
