Lens And Main Unit Cleaning - Toshiba TDP ET20/U Owner's Manual

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 drop 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 deter-
gent 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.
