nents are subject to wear and must be replaced.
Include the following tasks in your maintenance schedule
D Clean the surface of the screen at least once a week with an anti static
cloth or window cleaning agent containing denatured alcohol.
CAUTION
Dissolution of sealed key panel surface and display seal through
contact with solvents!
Do not use any solvents (e.g., paint thinner)!

tions of the components are correctly seated and not damaged. Check
that cables are not broken or crushed. Replace damaged parts immedia-
tely.
D Check fan and fan filter mats at least once a year.
Clogged and contaminated filter mats reduce the air volumes required for
proper ventilation and cooling. Therefore, wash dirty filter mats in soapy
water or replace with new mats. Allow washed filter mats to dry tho-
roughly before reinstalling.

Risk of injury through rotating fan impeller!
Keep hands and fingers clear, and do not insert any items into the fan
impeller.
