12.1 Cleaning the lens
To minimize the possibility of damage to optical coatings, or scratches to lens surfaces, we have developed
recommendations for cleaning. FIRST, we recommend you try to remove any material from the lens by blowing
it off with clean, dry deionized air. DO NOT use any liquid to clean the lenses.
Necessary tools
Toraysee
TM
cloth (delivered together with the lens kit). Order number : R379058.
How to clean the lens ?
1. Always wipe lenses with a CLEAN Toraysee TM cloth.
2. Wipe lenses in a one single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Do not leave the cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smears are the fi rst indication of a dirty cloth.
C
AUTION
:
Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the
cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
Other lenses can also be cleaned safely with this Toraysee TM cloth.
12.2 Cleaning the exterior of the DML-1200
How to clean the exterior
1. Unplug the power cord.
2. Clean the housing with a damp cloth. Stubborn stains may be removed with a cloth lightly dampened with a mild detergent
solution.
12.3 Level check of cooling liquid
What should be done ?
The projector is liquid cooled. When running with a low liquid cooling level then the cooling capacity is strongly reduced which results
in higher temperatures inside the projector. These higher temperatures can cause an interruption of your show as the lamps can be
switched off by the software as a preventive step.
