9 CLEANING AND MAINTENANCE
The screen and the DigiOptic™ Image Processor do not require in-
ternal adjustments and do not contain any user-serviceable parts.
For any service requirements seek qualified technical assistance
from your nearest Dealer.
To clean the outer cover of the screen use a soft cloth and moisten
slightly if necessary with water and a small amount of neutral soap.
Do not rub hard on the printed captions on the rear panel of the
DigiOptic™ Image Processor.
The screen may be cleaned with a very soft non-abrasive brush in
order to remove dust particles. Alternatively, use a soft dry cleaning
cloth (of the type used to clean spectacles) to remove fingerprints
and grease marks.
