Problem: Image is reversed or inverted.

Use the OSD Advanced Menu to change the Rear or Ceiling option

to display the image properly.

Problem: No sound.

Make sure the audio cables and other cables are connected

properly.

Problem: Remote control does not work.

Check for one of these possible problems:

• Are you too far from the projector? The remote control has a

range of about 10ft (3m) and needs to be within 20° of the

sensor. Move closer to the projector and try again.

• Is anything blocking the infrared sensors on the projector?

Make sure the infrared sensors are not covered or blocked

from receiving signals from the remote control.

• Are the batteries in the remote control dead? Replace the

batteries in the remote control.

Problem: Lamp burns out or makes a popping sound.

When the lamp reaches its end of life, it may burn out and may

make a loud popping sound. If this happens, do not attempt to turn

on the projector until the lamp module has been replaced. See

“Changing the Lamp” on page 28 to replace the lamp.
