16.1  Cleaning and Replacing the Dust Filters
The filters must be cleaned regularly to allow an efficient air intake. Otherwise, dirt may enter the unit and appear
on the screen, preventing you from enjoying the video fully. If dirt has entered the unit or if you need information
about the filter, please consult your authorized dealer. A filter cleaning warning appears every 500 hours.
Cleaning procedure
• Pull out the power plug from the outlet while the projector is in standby mode.
• Push up and lift the claw of the filters, pull out the filters.
• Clean the filters with water and dry them, avoiding direct sunlight. In extremely soiled cases, use of a neutral
detergent is recommended. Insert the filters in their original positions and make sure that the claws are firmly
inserted.

16.2  Dirt on the Lens
The lens shall be cleaned 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. The lens surface is
fragile. Avoid rubbing it hard or knocking.
16.3  Replacing the Lamp
Light-source Lamp and Lamp Usage Time
The life of light-source lamps used for this unit is about 4500 hours when running this unit in low lamp power
mode.
• When the lamp power is set to Low, the lamp life is approximately 4500 hours. This average lamp life is not
guaranteed and may not reach 4500 hours depending on the operating conditions. Get ready or replace with
a new lamp when the accumulated usage time exceeds 4500 hours. Depending on the operating conditions,
the lamp may have to be exchanged earlier. If the image is dark or if the color tone is abnormal, replace the
lamp as soon as possible.
• When the lamp life time exceeds 2900 hours, a warning message is displayed, press the [BACK] button to
clear it and replace the lamp before the lifetime reaches 4500 hours.
ABOUT LAMP REPLACEMENT
If this unit is installed in a constricted place, attempting to replace the lamp in that place may cause injury.
Use only genuine replacement parts for the lamp unit. Otherwise, malfunction may occur.
Do not replace the lamp immediately after this unit has been used. The temperature of the lamp is still
high and this may cause a burn. Allow a cooling period of 1 hour or more before replacement.
Before replacing the lamp unit, pull out the power plug from the outlet and wait until the STANDBY/ON
led is still light red.
