CLEANING AND MAINTENANCE

Warning
• Do not remove any screws other than those specified ("
The high voltage and high temperature inside the projector may lead to electric shock or burns if touched.
PRECAUTIONS ON AIR FILTERS AND LAMP PROTECTION FILTER
• If the ventilation holes become blocked, the temperature inside the projector rises and the lamp will fail to light. Clean the ventilation
holes about once every 6 months. Cleaning will be required more frequently if used in a particularly dusty environment.
• When the air filter of the ventilation hole becomes hard to clean, it is ready to be changed. Purchase a new air filter (with the filter
holder).
• Do not use the projector with the filter holder detached, as dust and debris may get into the projector, causing them to appear on the
projected screen.
