Precautions on lamp unit replacement
Timing of lamp unit replacement
The lamp units are consumable parts. The lamp brightness decreases gradually as the cumulative operating time
increases, so periodic replacement is necessary. The replacement guideline is 2 000 hours*1, although the lamp
may become dead (will not light) before 2 000 hours*1is reached depending on the characteristics of individual
lamps and other factors such as the operating conditions and the installation environment. Therefore, it is
recommended for the user to keep a spare lamp unit.
The risk of the lamp bursting increases after 2 000 hours*1of operation, so the lamp unit turns off automatically.
After
1 800 hours*2
The indication appears for 30
seconds or until any control button
is pressed.
On-screen indication
After
2 000 hours*1
The indication will not disappear

*1This is the operating time if the lamp has only been used at the LAMP POWER “HIGH” setting. If the lamp
has only been used at the LAMP POWER “LOW” setting, the operating time is 3 000 hours. When the lamp
has been switched from LAMP POWER “HIGH” to “LOW”, the cumulative operating time from the
conversion formula below will be 2 000 hours.
Lamp operating time = LAMP POWER “HIGH” operating time + (LAMP POWER “LOW” operating time x 2 ÷ 3).
*2This is the operating time if the lamp has only been used at the LAMP POWER “HIGH” setting. If the lamp
has only been used at the LAMP POWER “LOW” setting, the operating time is 2 700 hours. When the lamp
has been switched from LAMP POWER “HIGH” to “LOW”, the cumulative operating time from the
conversion formula below will be 1 800 hours.
Lamp operating time = LAMP POWER “HIGH” operating time + (LAMP POWER “LOW” operating time x 2 ÷ 3).
• It is not possible to turn on the power unless two lamp units are installed.

Air filter replacement procedures
When replacing the lamp unit, also replace the air filter.
After turning the power off following the Operating Instructions of the projector,
remove the power plug.
Remove the air filter.
The projector has two same
air filters, one at the right
and the other at the left.
Pull the air filter tab toward
you, and remove it from the
main unit.
Set the air filter.
Install the air filter in the reverse order to step .
Install the air filter into place with the filter material facing the back.
• The air filter must be installed in place when using the projector.
Using the projector without the air filter installed inside, dirt and dust are sucked into the projector,
causing failure.
• Clean the air filter section once every 100 hours or so as a guideline depending on the location of
projector operation.
• Do not rinse off the air filter with water. Doing so will impair the filter’s ability to provide protection
from dust.
