The life of the lamp
The average life of the lamp for the projector is about
2,000 hours of consecutive use. Life span may differ
according to operating environment, and may be shorter
than 2,000 hours. Decreases in luminescence and/or
color brightness will indicate that the light source lamp
needs to be replaced. When lamp operation time ex-
ceeds 1,500 hours, the indicator will flash alternately
between green and red (while the lamp is in operation;
when the lamp is not in operation, the indicator will
appear red only).   When the lamp has been used for
about 1,900 hours, the message “LAMP!!.” will appear
on the screen for one minute. When the lamp has been
used for about 2,000 hours, the projector will automati-
cally shut off for the safety of the lamp and the power
indicator light will be red. The projector cannot be used
until the lamp has been replaced and operation timer
has been reset.
Caution:
• The lamp is fragile. If broken, be careful not to cut
yourself with glass fragments.
• The lamp life depends on the environment. For re-
placement lamps, please contact your dealer.
The projector automatically shuts off af-
ter about 2,000 hours, and you cannot use

Cleaning the air-filter
This projector has two air-filters, for bottom air-outlet
slots and for front air outlet slots. Clean the air-filter
frequently. If the filter or ventilation slots become clogged
with dirt or dust, the temperature inside the projector
may rise and shut off the power (the TEMP indicator
starts to blink red).
For bottom air outlet slots
1. To remove the filter cover, press the ridged
area gently, push the cover in the direction
of the arrow and lift.
2. Remove the air-filter from
the filter cover.
3. Wash the air-filter.
•Use water or a mild
detergent diluted with

Rinse the filter thoroughly and let it dry
completely.
4. Attach the filter to the cover.
5. Reinstall the filter cover.
For front air outlet slots
1. To remove the filter cover, press the
two ridged area gently and pull the cover.
2. Remove the dust from the
air-filter by using a vacuum
cleaner.

AP – 3 3) Control sequence
(1) The command from a personal computer to the projector will be sent in 400ms.
(2) The projector will send a return command 400ms* after it has received an encode. If the command isn’t
received correctly, the projector will not send the return command.
(3) The personal computer checks the command and confirms if the command which has been sent has been
executed or not.
(4) This projector sends various codes other than the return code. When having a control sequence by RS-
232C, reject other codes from personal computer side.
•* : The sending time of return command may delay depending on the condition (during changing the
input signal, etc.).
