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.),
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.
