Cleaning the Air Filter
✔ Note: Clean the air filter about every 100 hours or if the message “CHECK AIR FLOW” is
displayed on the screen. If air is restricted due to dust accumulation on filter, the
projector may overheat and shut down automatically.
Turn off the MAIN POWER SWITCH of the projector and pull out power cord. Let cool for
20 minutes. Vacuum dust and dirt from filter. If the filter cannot be cleaned and needs to be replaced,
please consult your dealer.
Figure 5.1 Cleaning Air Filter
Section 5: Maintenance
K

dry with a soft, clean cloth.
Caution
•Turn off the power and remove power cord from outlet before beginning any
maintenance work.

To determine the lamp operation hours:

20 HOURS” will appear when 20 or less lamp hours remain. The number of hours
left until shutdown will decrease until 
0 hour is reached, then power will turn off automatically.
✔ Note: After normal lamp operating time has expired, the projector will only run for 10-minute
intervals when restarted until the lamp is replaced and the lamp timer is reset. The
message “CHANGE THE LAMP” will blink at projector startup to remind you to
change the lamp.
Reset Lamp Hours
The lamp operation hours must be reset after changing the lamp. When the lamp has been replaced after the

within 10 minutes after switching on the power. Otherwise, the power will automatically shut down after 10
minutes.

on the remote control and hold for three seconds. The “LAMP xxxx hr” message will display at
the bottom of the screen.
