Lens and main unit cleaning
WARNING
•
Request cleaning and maintenance of a ceiling-mounted unit from your projector dealership
.
Attempting to clean/replace the lamp at a high site by yourself may cause you to fall
down, thus resulting in injury.
■ Lens cleaning
• Clean the lens with a commercially available blower and/or
lens cleaner.
• The lens is easily scratched, so do not rub it with hard objects,
or strike it.
■ Main unit cleaning
• Clean the main unit after unplugging the power cord.
• Wipe dirt off the main unit gently with a soft cloth.
• If the soiling is severe, dip the cloth in a neutral
detergent diluted in water, wring well, and gently wipe
off the dirt, then finish up by wiping with a dry cloth.
● Replacing cooling fans
To maintain the performance, it is recommended that cooling fans should be replaced
about every 2 to 3 years. Consult with your dealer for details.
