Cleaning the Air Filter
✔ Note: Clean the air filter about every 50 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.
1. Turn off the MAIN POWER switch of the projector and pull out power cord. Let cool for
20 minutes.
2. Push tab up slightly and lift the air filter cover upward and outward to remove it.
3. Vacuum dust and dirt from filter, then place it back in the air filter cover.
4. Replace the air filter cover by inserting the plastic teeth of the air filter cover into their slots and
swinging the door back down until the tab snaps into place.

Section 6: Lamp
Lamp
The following symptoms may indicate that the lamp needs to be replaced:
• LAMP indicator lights up red.
• “CHANGE THE LAMP” message appears on the screen.
Display Lamp Operation Hours
To determine the lamp operation hours:
1. While the projector is running, press and hold the TIMER button on the remote control for three
seconds.
2. The operating time of the lamp will be displayed at the bottom of the screen.  The message
“CHANGE THE LAMP, AFTER REPLACING LAMP RESET THE LAMP TIMER” will appear
after the lamp has reached the end of the normal lamp life. The message “POWER WILL TURN
OFF AFTER 
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 start-up 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
LAMP indicator is red, or the CHANGE THE LAMP message displayed, you must complete the folowing
within 10 minutes after switching on the power. Otherwise, the power will automatically shut down after 10
minutes.
1. To display the total lamp hours, press the RESET button on the projector or the Timer button
on the remote control and hold for three seconds. The “LAMP xxxx hr” message will display at
the bottom of the screen.
2. To reset the lamp timer, press the RESET button on the projector or MENU button on the
remote while the amp hours are displayed. The lamp hour reset message will display. Use the
left-arrow button on the remote control or the Menu diskpad of the projector to select 0, and wait
until the timer display has cleared.
