Simple maintenance procedures
Cleaning the display unit
Where marks on the screen can’t be removed by a microfiber cloth,
use a 50/50 mixture of warm water and isopropyl alcohol to clean
the screen. Avoid any contact with solvents (acetone, mineral tur
-
pentine 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.
