recommended operating temperature and must be allowed

to cool down before it may be used. Please check the

Please also check the dust filters if they are installed. If the

dust filter is clogged with dust, please clean it. Please refer to

"Cleaning and replacing the dust filters (Option)" for details.

# Condition Solution

1 The projector stops responding

to all controls

If possible, turn off the projector, then

unplug the power cord and wait at least 30

seconds before reconnecting power.

2 Lamp burns out or makes a

popping sound

When the lamp reaches the end of its useful

life, it will burn out and may make a loud

popping sound. If this happens, the projector

will not turn on until the lamp module has

been replaced. To replace the lamp, follow

the procedures in the "Replacing the Lamp"

section.
