• Install the projector so that it is parallel to the screen. If the projector is installed at an angle to the screen, keystone distortion occurs in the projected image.

• Place the projector on a level surface. If the projector is tilted the projected image is also tilted.

• See the following if you cannot install the projector parallel to the

screen. s "Correcting Keystone Distortion" p.40

• See the following if you cannot install the projector on a level surface.

s "Adjusting the Horizontal Tilt" p.45 s "Correcting Keystone Distortion" p.40

Screen Size and Approximate Projection Distance

Projection size is determined by the distance from the projector to the screen. See the illustrations on the right to select the best position according to the screen size. The illustrations show the approximate shortest distance at maximum zoom. See the following for more information on the projection distance.

"Screen Size and Projection Distance" p.128

When you correct keystone distortion, the projected image may be

reduced.

Attention

If the orientation or shape of the plug differs, do not try to force it in. The device could be damaged or could malfunction.

• You can change the audio input source in Audio Output.

s Extended - A/V Settings - Audio Output p.89

• If the source you want to connect to has an unusually shaped port, use the cable supplied with the device or an optional cable to connect to the projectors.

• When using a commercially available 2RCA(L/R)/stereo mini-pin audio cable, make sure it is labeled "No resistance".

Connecting USB Devices

Only EB-X21/EB-S21/EB-X17/EB-S17 are supported.

You can connect devices such as USB memory, the optional Document Camera, and USB compatible hard disks and digital cameras.

Using the USB cable supplied with the USB device, connect the USB device to the USB-A port on the projector.

When the USB device is connected, you can project image files on the USB memory or digital camera using PC Free.

"PC Free examples" p.52

Connecting Equipment

Attention

• If you use a USB hub, the connection may not operate correctly. Devices such as digital cameras and USB devices should be connected to the projector directly.

• When connecting and using a USB-compatible hard disk, make sure you connect the AC adaptor supplied with the hard disk.

• Connect a digital camera or hard disk to the projector using the USB cable provided with the device.

• Use a USB cable less than three meters in length. If the cable exceeds three meters, PC Free may not function correctly.

Removing USB devices

After finishing projecting, remove USB devices from the projector. For devices such as digital cameras or hard disks, turn off the device and then remove it from the projector.

Connecting External Equipment

You can output images and audio by connecting an external monitor or speaker.

When outputting images to an external monitor

Connect the external monitor to the projector's Monitor Out port using the cable supplied with the external monitor.

When outputting audio to an external speaker

Connect the external speaker to the projector's Audio Out port using a commercially available audio cable.

Connecting Equipment

• If you set Standby Mode to Communication On, you can perform the following operations even if the projector is off.

- Outputting images to an external monitor (only when A/V Output is set to Always On).

- Outputting audio from an externally connected speaker (audio from USB or LAN cannot be output).

s ECO - Standby Mode p.99 s Extended - A/V Settings p.89

• Only analog RGB signals from the Computer1 port can be output to an external monitor. You cannot output signals input from other ports or component video signals.

• Setting gauges for functions such as Keystone, Configuration Menu, or Help screens are not output to the external monitor.

• When the audio cable jack is inserted into the Audio Out port, audio stops being output from the projector's built-in speakers and switches to external

output.
