The lamp time and warning mode are indicated using the indicator.
For indicator displays during normal operation, refer to the note below.
*1: The indicator lights up in red when in the standby mode, and in green when in the operating mode.
*2: The indicator lights up in red when in the warning mode, and blinks in red when in the cool down mode.
 Measures when the warning mode appears
When the projector switches to the warning mode (Nos. 3 to  9), projection stops automatically, and the cooling fan runs for 
about 180 seconds.
After the cooling fan stops running, turn off the main powe r supply switch, and remove the power plug from the outlet.
Perform the follo wing checks and take the  corresponding measures.
If the warning indication is displayed again, turn off the ma in power supply switch after the cooling fan stops running.
Then pull out the power plug from the power  outlet. Call your authorized dealer for repair.
NOTE:

Cleaning and Replacing the Filter
Clean the filter regularly. If the filter is soiled, air intake efficiency may deteriorate, thus resulting in malfunction of the 
product. Replace with a new one if the filter fails to remove dust thoroughly or if it is damaged. Failure to do so may cause 
dust to enter the projector and shadows to appear on the projected image.
If dirt has entered this product or if you need to purchase the filter, please consult the authorized dealer from which this 
product is purchased or any nearby JVC servicing center.
MaintenanceTurn off the power of the projector unit, 
and unplug the power cord when 
cleaning or replacing the filter.

							59
1 Remove the filter cover
The filter is located at the front side of the projector 
unit.
2 Remove the sponge and filter
Hold the center of the filter using your fingers, and pull 
the filter toward you to remove it.
3 Clean the sponge and filter
Remove any dirt or dust using a vacuum cleaner.
CAUTION:                                                                      
●Do not clean using a flammable air duster. This may 
cause fire.
4 Mount the sponge and filter
Mount the filter and sponge to the projector using the 
reverse removed procedure.
Finally, check to ensure that the filter cover is firmly 
mounted.
NOTE:                                                                             
●Mount the filter correctly. Failure to do so may cause 
the projector to malfunction.
●The projector may stop operating if a damaged filter or 
filter panel is used. In this case, replace the filter or 
filter panel with a new one.
Routine Servicing
Clean dirt on the cabinet
Do this with a soft cloth. In case of heavy soiling, soak a 
cloth in neutral detergent diluted with water, wring dry 
and wipe, followed by wiping again using a dry cloth.
Pay attention to the following to prevent the cabinet from 
deteriorating in condition, getting damaged, or the paint 
from coming off.
●Do not wipe with a stiff cloth
●Do not wipe with force
●Do not wipe with thinner or benzene
●Do not spray volatile chemicals like insecticide
●Do not allow prolonged contact with rubber or 
plastic products
Remove dirt that is attached to the vent holes
Do this using a vacuum cleaner. Wipe using a cloth if a 
vacuum cleaner cannot be used. Leaving dust attached 
may prevent adjustment of the internal temperature and 
result in malfunction of the projector.
Clean dirt on the lens
Do this using commercial blowers or lens cleaning 
papers (for cleaning glasses and cameras).
Do not use fluid-type cleaning agents. This may lead to 
peeling of the surface coating film.
Lens surface is fragile. Avoid rubbing or knocking it.
Replacement of Light Source 
Lamp
The light source lamp is a consumable item. Replace 
with a new lamp unit if the image appears dull or if the 
lamp burns out.
●When the lamp needs to be replaced soon, users will 
be notified through a message on the screen and the 
indicator. (APage 53, 54)
●The life of the lamp used for this projector is about 
2000 hours.
This is the average life of lamps, and not a guaranteed 
value.
●The lamp life may not reach 2000 hours depending on 
the operating conditions.
●Deterioration progresses rapidly when the remaining 
lamp usable time is short.
●If the image is dark or color tone abnormal, replace the 
lamp unit as soon as possible.
●For details on replacement of the lamp unit, please 
consult your authorized dealer.
●Lamp has to be replaced by an authorized person. 
Do not remove LAMP DOOR and lamp unit. This may 
cause fire and electric shock hazards. Access to the 
lamp unit only possible with use of tool.
