Important
Information
„ Do not touch the surface of the projector lens with your bare hand.
If the surface of the lens becomes dirty from fingerprints or anything else, this will be magnified and projected
onto the screen. Please put the lens cover on the projector when you do not use it.
Do not move the projector while it is operating or subject it to vibration or „
impact.
The service life of its internal components will be shortened.
The projector has a high pressure mercury lamp that is characterized as „
follows:
The brightness of the lamp will decrease over time. z
The lamp may explode or shorten the lamp life by shocks or chipping damage. z
In rare cases, it may burst shortly after the first use. z
The possibility of its bursting increases when the lamp is used beyond the replacement time. z
If the lamp bursts, gas inside the lamp is released in the form of smoke. z
The life of a mercury lamp varies according to the individual difference or conditions of use. z
In particular, turning the power on and off frequently and/or repeatedly as well as continuous use for 22 hours z
will greatly affect the life cycle. Provide a lamp for replacement in advance.
Lamp deterioration accelerates when used continuously for 22 hours or more. Lamp deterioration due to z
continuous use can be reduced by using the “LAMP RELAY” function.
Connection to external device „
When connecting the projector to a computer or external device, use the power cord supplied with the
corresponding device and a commercially available shielded interface cable.
Optical components „
It may be necessary to replace the optical components such as DLP chips and Polarizing plates in less than 1
year if using the projector in a high temperature environment or in a very dusty, oily smoke or tobacco smoke
environment. For more details, please contact your dealer.
DLP chips „
The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit,
but this is not a malfunction. Please take note that directing a laser beam onto the lens surface can damage the
DMD element.
Cleaning and maintenance
Ask an Authorized Service Center to clean the inside of the projector at „
least once a year.
If dust is left to build up inside the projector without being cleaned out, it can result in fire or problems with
operation. It is a good idea to clean the inside of the projector before the season when humid weather arrives.
Ask your nearest Authorized Service Center to clean the projector when required.
Please discuss with the Authorized Service Center regarding cleaning costs.
Be sure to remove the power plug from the wall outlet before cleaning. z
Use soft and dry cloth to clean the cabinet. z
Use a soft cloth moistened in warm water to clean away oil. Do not use solvents such as benzene, thinner,
and alcohol, detergents for kitchens, or a chemical cloth. If using such solvents, the outer case will become
deformed, and the paint may peel off.
Do not clean the lens surface with fuzzy or dusty cloths. z
If dust adheres to the lens, it will be magnified and projected on the screen. Use a soft and clean cloth to wipe
off dust.
