Cleaning your display
Front glass
Before cleaning the front glass, unplug the power cable from the mains to prevent the keys from being activated inadvertently by sweeping over them.
Clean the front glass using a sponge, cleaning cloth or soft tissue, lightly moistened with one of the following tested products:
•Flux
•Windex Glass Plus
•Bohle glass cleaner
•Mr. Proper
•Pril
•Ajax glass cleaner
•Sidolin glass cleaner
In case none of the above cleaning products is available, use plain water.
Take care not to damage or scratch the front glass. Be careful with rings or other jewelry and do not apply excessive pressure on the front glass.
Do not apply or spray liquid directly to the front glass as excess liquid may cause damage to internal electronics. Instead, apply the liquid to the cleaning cloth.
