							Cleaning and replacement of air filter
43
• If cleaning cannot remove the dust completely, then it is a sign to replace the air filter. Consult the
dealer. In addition, when the lamp unit is replaced, also replace the air filter.Note If too much dust is deposited in the air filter, temperature inside the main unit will rise and the temperature monitor
(TEMP) blinks, eventually turning off the power supply.
Clean the air filter section once every 100 hours or so as a guideline depending on the location of projector
operation.
Procedure of cleaning
Turn off the main power and remove the power plug from the receptacle.
Turn off the main power supply observing the procedure (How to turn “OFF” the power supply) on page 23
and then remove the power plug.
Dismantle the air filter.
Use your finger to pull the air filter tab toward you, and remove it from the main unit.
Set the air filter.
Set the air filter in the reverse order to step  .
Clean the air filter.
Suck off deposited dust with a vacuum cleaner.
• Do not suck in the air filter itself.Attention
• Install the filter material (looks like sponge) such that it is positioned on the left side when you
face the filter.

A used lamp unit may burst if it is handled violently.
For disposition of used lamps, request an industrial waste disposal contractor.
Do not reset the cumulative time, except when the lamp unit has been replaced with a new unit.
If you continue to use a lamp after the replacement time, the lamp may break.

Long life lamp unit model No.: ET-LAD35L (single bulb)
Rating: 160W
• Other lamps than specified above cannot be used. Be sure to use the specified lamp.Attention
Timing of lamp unit replacement
The lamp used for the light source has its due life. The life of light source lamp used in the main unit is 1 500
hours1(when lamp output is HIGH). However, it may happen that the lamp becomes dead (will not light) by the
time of 1 500 hours1depending on the characteristics of individual lamps and working conditions (lamps may
reduce their life affected by the times of lighting and the intervals between previous lighting and next lighting).
Therefore, it is strongly recommended for the user to keep a spare bulb.
If your lamp unit is not replaced after 1 300 hours
2(with the lamp output set at “HIGH”), power supply will be
turned off automatically at the time of 1 500 hours1, entering a standby state. After 1 500 hours1of initial
lighting, power supply is turned off automatically about 10 minutes later, entering a standby state even if it is
turned on again.
Indication after 1 300 hours2(with the lamp output set at “HIGH”)
When lamp unit used hours have reached 1 300 hours2, lamp monitor
(LAMP) light up including standby state.
Further, an on-screen indication will appear for about 30 seconds as
shown in the diagram on the left, recommending replacement of lamp unit.
(The indication on the left diagram will disappear after about 30 seconds or
when either control button on the upper panel of main unit or remote
control button is operated.)
After the time of 1 500 hours
1, the on-screen indication will not disappear
unless the menu (MENU) button is operated.
REPLACE LAMP
1 This time period is 4 000 hours when long life lamp units are used.
