Other Problems
The projector stops responding to all controls
If possible, turn off the projector, then unplug the power cord
`
and wait at least 20 seconds before reconnecting power.
Lamp burns out or makes a popping sound
When the lamp reaches its end of 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.
Remote Control Problems
If the remote control does not work
Check the operating angle of the remote control is within ±15°
`
both horizontally and vertically of on of the IR receivers on the
projector.
Make sure there are not any obstructions between the remote
`
control and the projector. Move to within 6 m (20 ft) of the
projector.
Make sure batteries are inserted correctly.
`
Replace batteries if they are exhausted.
