documentation for specific information.
■If you’re projecting a wide panel computer image, adjust the 
Resolution setting (see page 58).
■If you’re projecting an image from a computer with dual display 
activated, turn dual display off.
The image isn’t square, but keystone-shaped.
If the image isn’t square or rectangular, adjust its shape as described on 
page 30.
The image contains static or noise.
■Make sure the cables are securely connected.
■If you’re using a computer cable longer than 6 feet (1.8 meters), 
or an extension cable, the image quality may be reduced.
■Keep your computer and video cables away from the power cord 
as much as possible to prevent interference.

e-mail notification function has been turned on.
■Make sure the mail notification function is set correctly in the 
configuration menu. See page 47.
■Set Standby Mode to Communication On in the Extended 
menu. Otherwise, the projector cannot send e-mails when it is in 
Standby mode (when the power is off).
■If a critical problem develops with a projector which causes it to 
suddenly stop working, it may not be possible for the projector to 
send a message.
■Make sure the projector is plugged in.

Solving Problems With the Remote 
Control
The projector doesn’t respond to remote control commands.
■Point the remote control towards the receiver.
■Make sure the projector and remote control IDs match. To 
operate all projectors by remote control regardless of ID settings, 
set the ID switch on the side of the remote control to 
Off.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 82. 
■Make sure you are within about 49 feet (15 meters) of the 
projector and within range of the projector’s front or back sensor.
■Dim the room lights and turn off any fluorescent lights. Make 
sure the projector is not in direct sunlight. Strong lighting, 
especially fluorescent lights, may affect the projector’s infrared 
receivers. Also, turn off any nearby equipment that emits infrared 
energy, such as a radiant room heater. If necessary, use the 
Remote Receiver setting to disable the projector’s front or back 
sensor if it continues to pick up interference (see page 61).
■Make sure the Remote Receiver setting isn’t disabling both of 
the projector’s sensors (see page 61).
■If any buttons are held for longer than 30 seconds, the remote 
enters sleep mode. Release any button that is held to wake the 
remote.
■Make sure the Remote Control Type setting is correct. See 
page 67.
