8.0 MAINTENANCE
8.1 Clean Dirt on the Cabinet
Always use 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.
Caution
Pay attention to the following as the cabinet may deteriorate in condition, get damaged or paint may come
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.
8.2 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.
8.3 Replacing the Lamp
Light-source Lamp and Lamp Usage Time
The life of light-source lamps used for this unit is about 2000 hours.
•The lamp life of 2000 hours is merely the average life span of light-source lamps and we do not provide any
guarantee for this figure. The lamp life may not reach 2000 hours depending on the operating conditions.
Deterioration progresses rapidly when the remaining lamp usage time is short. Get ready or replace with a new
lamp when the accumulated usage time exceeds 1900 hours. Depending on the operating conditions, the lamp
may have to be exchanged earlier.
If the image is dark or color tone abnormal, replace the lamp as soon as possible.
•Y ou can also check the accumulated hours of usage. Please refer to Lamp Time of the Information menu.
• Setting Power Save of the Options menu to On does not affect the usage time of the light-source lamp.
Please consult your authorized dealer when purchasing a new lamp unit.
When the lamp usage time exceeds 1900 hours (but less than 2000 hours
The [LAMP] indicator lights On orange and the Lamp replacement message will be displayed on the screen when
projection starts.
• The message can be cleared by pressing any button on the remote control or this unit.
When the lamp usage time exceeds 2000 hours
The [LAMP] indicator lights On orange and the Lamp replacement message will be displayed on the screen when
projection starts and the Warning mark will appear blinking.
• Press the [EXIT] button to clear the display. However, the same Warning and Lamp replacement messages will
be displayed after 1 hour.
• When the unit is switched to the standby mode or turned off after the lamp usage time exceeds 2000 hours, it
cannot be switched back to the projection mode again. In this case, replace with a new lamp and reset the lamp
time.
• The projection mode (operating mode) cannot be restored until a new lamp is replaced and the lamp time reset.

Procedure for Lamp Replacement
During the lamp replacement process, you may have access to sensitive parts of the projector.
•Open the lamp Cover, on the side of the projector.
• Loosen the 2 screws on the lamp unit and lift up the handle.
• Pull out the lamp unit.
• Insert the new lamp unit until it is fully in.
• Tighten the screws of the lamp unit and close the handle.
• Attach the lamp cover and fasten the screw.
Resetting Lamp Time
After installing a new lamp, reset the lamp time. The lamp time counter will be reset and a new count
will start. 
If the accumulated lamp time has reached 2000 hours, this unit will not work (lamp does not light
up) unless the lamp time is reset.
a) Insert plug into the power outlet
The main power turns on and the [STANDBY/ON] indicator on the unit lights up. b) Press the [EXIT], [ENTER] and [HIDE] buttons sequentially, then press the [DOWN] button for 2 seconds or
more.
• The [STANDBY/ON] indicator will alternately blink for a duration of about 3 seconds each. After blinking stops,
lamp time resets and the unit returns to the standby mode ([STANDBY/ON] indicator lights up red).
8.4 Cleaning and Replacing the Dust Filter
The filter must be cleaned regularly to allow an efficient air intake. If the filter is extremely dirty and cannot
be cleaned, or if it is damaged, replace the filter with a new one. 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.
Pull out the plug from the power outlet
Pull out the power plug from the outlet while the [STANDBY/ON] indicator is still on.
Remove the inner filter
Push up and lift the claw at the base of the inner filter, followed by drawing out the filter.
ABOUT LAMP REPLACEMENT
If this unit is installed in a constricted place, attempting to replace the lamp in that place may cause injury. Move this
unit to a place large enough to perform work.
Use only genuine replacement parts for the lamp unit. Otherwise, malfunction may occur. Also, never attempt to re-
use an old lamp unit. This may cause marked performance deterioration or lamp blowout, thus leading to unit
malfunction. Broken pieces of the lamp outside this unit may also cause injuries during lamp unit exchange.
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 while the [STANDBY/ON] indicator is still light
red. Replacing a lamp with the plug connected to the outlet may cause injuries or electric shocks.
TO ENSURE THE LAMP TIME HAS BEEN RESET
The lamp time can be checked via the Lamp Time item of the Information  menu.
CAUTION DURING RESET WORK
Reset the lamp time only when you have replaced the lamp.
Never reset it when the lamp is still in use.
Otherwise, the approximate standard for gauging replacement time may be inaccurate, lamp performance may
deteriorate and lamp blowout may occur.
