to cool down - seek technical assistance from your nearest
service centre.
• Check the state of the connection by using Table 1 to
interpret the code displayed by the system LEDs.

9 CLEANiNg AND MAiNTENANCE
The projector does not require internal adjustment.
There are no user serviceable parts inside the projector.
To replace the bulb or any other repairs, contact your local
service centre, whose engineers will be happy to efficiently solve
any problem. Use a soft cloth to clean the projector housing, if
necessary slightly dampened with water and a small amount
of neutral soap. Do not rub the rear panel markings.
The lens may be cleaned with a small very soft, non-abrasive
brush, to remove dust particles. Alternatively, use a soft dry
cleaning cloth (of the type used for camera lens cleaning) to
remove fingerprints and grease marks.
we suggest cleaning the filter every time that the lamp is
changed.
