MAINTENANCE

  

Make sure the lens cap is removed.

  

Make sure the projection screen is between the required distance 

4.92 to 32.8 feet (1.5 to 10.0 meters) from the projector.

  

Adjust the zoom lever on the top of the projector.

  

Move the projector closer to or farther from the screen.

  

Press [4:3] / [16:9-I] / [16:9-II] / [Native] button on the remote 

control or [Projector menu] on the projector panel, go to “Display--

>Format“. Try the different settings.

  

As possible, reposition the projector so that it is centered on the 

screen and below the bottom of the screen.

  

Press [Keystone +/-] button until the sides are vertical on the 

remote control.

  

Select “System-->Projection” from the OSD and adjust the projec-

tion direction.

  

If possible, turn off the projector, then unplug the power cord and 

wait at least 20 seconds before reconnecting power.

  

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 

on page 55.
