The projector automatically corrects images that are distorted 
when the projector is tilted up or down (up to a 15° tilt). The 
Keystone window appears on the screen while the projector 
makes the correction. If the projected image still isn’t 
rectangular or has a “keystone” shape, do one or more of the 
following:
❏ If your image looks like 

 or 

, you’ve placed the 

projector off to one side of the screen, at an angle. Move it 
directly in front of the center of the screen, facing the screen 
squarely.

❏ If your image looks like 

 or 

, you may need to 

manually adjust the keystone correction value. Follow the 
directions below:
❏ To make keystone corrections using the projector’s 

Setting menu, press the 

Menu

 button on the projector or 

remote control. Select the 

Setting

 menu, then press 

Enter

. Select 

Keystone

 and press 

Enter

. Use the 

 

pointer button on the remote control (or the arrow 
buttons on the projector) to adjust the keystone setting as 
needed.

❏ To manually adjust the keystone correction value, press 

the 

 or 

 button on the projector to correct the 

shape of the image. After correction, your image will be 
slightly smaller.

The brightness of an image depends on the source you are 
projecting and the amount of light in the room. If the image is 
too bright or not bright enough, do one of the following:
❏ Change the 

Brightness

 setting in the Image menu. 

❏ Select 

Low

 or 

High

 for the 

Brightness Control

 option in 

the Setting menu. Low Brightness mode extends the life of 
the lamp and decreases the fan noise.

You may want to adjust the color mode to select a setting 
that is appropriate for the image you’re projecting and the 
environment in which you’re projecting it.

The following table lists the available color modes.  

To change the color mode, press the 

Color Mode

 button on 

the remote control until you see the mode you want. The 
currently selected setting appears in the upper right corner of 
the screen. You can also use the projector menu system to select 
the Color Mode in the Image menu.

When the projector has not received any input signals for 
30 minutes, it automatically turns off the projector lamp and 
enters “sleep mode.” This conserves electricity, cools the 
projector, and extends the life of the lamp. If you are done using 
the projector, unplug the power cord. If you want to start 
projecting again, press the P 

Power

 button. 

You can enable sleep mode in the Extended menu under 

Operation
