Cleaning The Projector Case; Cleaning The Lens - Epson dreamio EH-R4000 User Manual

Cleaning the projector case

Clean the projector case by wiping it gently with a soft
cloth.
If the projector is particularly dirty, moisten the cloth with
water containing a small amount of neutral detergent, and
then firmly wring the cloth dry before using it to wipe the
projector case. Then wipe the case again with a soft, dry
cloth.
Do not use volatile substances such as wax, alcohol or
thinner to clean the projector case. These can cause
the case to warp and make the coating finish peel off.

Cleaning the lens

To clean the lens it is preferable to use an air blower
purchased for the purpose. But alternatively you can wipe it
gently clean with a spectacle-cleaning cloth.
Do not rub the lens with harsh materials or subject the
lens to shocks, as it can easily become damaged.
