This section describes the simple maintenance procedures you should follow to clean the filter and replace the lamp.

 Cleaning or Replacing the Filter
The air-filter sponge keeps dust and dirt from getting inside the projector and should be cleaned after every 100 hours
of operation (more often in dusty conditions). If the filter is dirty or clogged, your projector may overheat.
CAUTION
•Turn off the projector, turn off the main power switch and unplug the projector before replacing the filter.
•Only clean the outside of the filter cover with a vacuum cleaner.
•Do not attempt to operate the projector without the filter cover.
To clean the air-filter:
Vacuum the filter through the filter cover.
To replace the filter (sponge):
1. Remove the filter cover by pushing down on the catch of the cover until you feel it detach.
Catch
2. Gently peel off the filter (sponge) and replace it with the new one.
To reset the filter usage time, from the menu, select [Factory default] → [Clear filter usage].
See also page 46 for resetting the filter usage time.

6. Maintenance
3. Reinstall the new filter cover.
NOTE: Do not wash the filter with soap and water. Soap and water will damage the filter membrane. Before replacing the filter,
remove dust and dirt from the projector cabinet. Keep out dust and dirt during filter replacement.
NOTE: When you replace the lamp, it is also wise to replace the filter. The filter comes in the same package with your
replacement lamp.
4. Turn on the projector.
5. Reset the Filter counter. See page 46.
 Cleaning the Cabinet and the Lens
1. Turn off the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled, use a mild detergent. Never use strong
detergents or solvents such as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to scratch or mar the lens.

 Replacing the Lamp
After your lamp has been operating for 2000* hours (up to 3000* hours in Quiet mode) or longer, the LAMP REPLACE
indicator in the cabinet will blink red and the message “Replace with the new lamp.” will appear. Even though the
lamp may still be working, replace it at 2000* (up to 3000* hours in Quiet mode) hours to maintain optimal projector
performance. After replacing the lamp, be sure to clear the lamp counter. See page 46.
CAUTION
•DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off,
wait 30 seconds, turn off the main power switch and then disconnect the power cord. Allow at least one hour for
the lamp to cool before handling.
•DO NOT REMOVE ANY SCREWS except two lamp case screws. You could receive an electric shock.
•Do not break the glass on the lamp housing.
Keep finger prints off the glass surface on the lamp housing. Leaving finger prints in the glass surface might
cause an unwanted shadow and poor picture quality.
•The projector will turn off and go into standby mode after 2100* (up to 3100* hours in Quiet mode) hours of
service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000* hours (up to
3000* hours in Quiet mode) of use, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp
case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your dealer for lamp
replacement.
*NOTE: Lamp life for LV-X5 is 3000 hours in Normal mode and 4000 hours in Quiet mode.
The projector will turn off and go into standby mode after 3100 (up to 4100 hours in Quiet mode) hours of service.
A lamp may burn out before the LAMP REPLACE indicator blinks.

 Optional lamp and tools needed for replacement:
•Replacement lamp LV-LP24 (LV-7245/LV-7240) or LV-LP25 (LV-X5)
