Cleaning the Air Filter
The air filter should be cleaned in every 100 hours.
When it becomes difficult to remove the dust from the
filter, replace the filter with a new one.
To clean the air filter, follow the steps below:
1
Turn off the MAIN POWER switch and unplug the
power cord.
2
Remove the air filter cover on the bottom of the
projector.
Replacing the Lamp
When it is time to replace the lamp, the message
“Please replace the LAMP.” appears on the screen
when you turn on the projector. Once the message
appears, replace the lamp promptly with a new PK-
PJ800 Projector Lamp (not supplied).
The message disappears if any key on the control panel
or the Remote Commander is pressed.
Notes
• If you continue to use the projector after the message
above has appeared, the following message appears.
When this message appears, no key except the
POWER ON/OFF keys will be operable.
• After turning off the power, wait at least for one hour
before changing the lamp to give it enough time to
cool down.
For details on replacement, refer to the instruction manual
supplied with the lamp.
Note
When the lamp is warm, it may not light up easily.
In this case,
88
appears in the error code display
window, but this is not malfunction.
If
88
remains lit for more than three minutes after
turning on the power, never open the lamp cover if
the projector is installed on the ceiling.
3
Remove the air filter.
4
Remove the dust from the filter with a vacuum
cleaner.
5
Attach the air filter and replace the cover.
Notes
• If the air filter is excessively dirty, wash it with a
mild detergent solution and dry it in a shaded place.
• Be sure to attach the air filter cover firmly; the power
will not be turned on if it is not closed securely.
