NO POWER (LEDS ALWAYS OFF)
• Check that the projector’s power switches are in posi-
tion I.

to the projector’s power sockets.

from your nearest service centre.
LAMP FAILS TO SWITCH ON
• If this happens immediately after the last time the unit
was switched off, allow a few minutes between switch-
ing off and switching on again. This will allow the lamp
to cool down to the optimum temperature for switching
on.
• If the lamp fails to light - even though the unit has had
time 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.

those of the selected input.

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.
