TEMPERATURE WARNING INDICATOR
The TEMPERATURE WARNING INDICATOR flashes red when the
internal temperature of the projector exceeds the normal temperature.
Possible causes for the temperature warning may be:
1. Ventilation slots of the projector are blocked. In such an event,
reposition the projector so that ventilation slots are not obstructed.
2. Air filter is clogged with dust particles. Remove dust from the air filter
by following instructions in the Air Filter Care and Cleaning section
below.
3. If temperature warning indicator remains on after performing the
checks listed above, cooling fan/internal circuits may be
malfunctioning. Request
service from an authorized dealer or service station.
AIR FILTER CARE AND CLEANING
The removable air filter prevents dust from accumulating on the surface
of the projection lens and projection mirror. Should the air filter become
clogged with dust particles, it will reduce the cooling fan’s
effectiveness and may result in internal heat build up and reduce the
life of the projector.
To clean the air filter, follow the cleaning procedures below:
1. Turn the POWER ON/OFF button OFF.
2. Remove the air filter cover.
3. Remove the air filter from the filter cover.
4. Clean the air filter with a vacuum cleaner.
5. Replace the air filter. Make sure that air filter cover is fully inserted.
Do not clean with water. Doing so may damage the air filter.
Do not operate the projector with air filter removed.
