Cleaning the Air Filter
The air filter should be cleaned every 300 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.
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 the cover is not closed
securely.
Replacing the Lamp
When it is time to change 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-
PJ500 lamp.
The message disappears if any key on the control panel
or the Remote Commander is pressd.
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 key will be operable.
•After turning off the power, wait at least one hour
before changing the lamp to give it time to cool down
completely.
For details on replacement, refer to the Instruction Manual
of the lamp.
