•Turn off the power of both devices before connecting.
•The figure below is a sample connection. This does not mean that all of these devices
can or must be connected simultaneously. (Dotted lines mean items can be exchanged.)
Notes
•COMPUTER terminals 1 and 2 function identically.
•For TDP-S21, the document camera should be connected to COMPUTER terminal 2.

Projection Distance and SizeUse the figures, tables, and formulas below to determine the projection size and projection distance.
(Projection sizes are approximate values for full-size picture with no keystone adjustment.)Placement StylesAs shown in the figures below, this device can be placed in 4 different styles.
The factory setting is “floor-mounted front projection.” Set the Projection mode in the
default setting menu 
p.32
, in accordance with your needs.
PlacementFloor-mounted front projection 
 WARNING
•Always obey the instructions listed in IMPORTANT SAFETY INSTRUCTIONS when placing the unit.
Attempting to clean/replace the lamp at a high site by yourself may cause you to drop down, thus
resulting in injury.
•If you wish to mount the projector on the ceiling, be sure to ask your dealer to do so. Mounting the
projector on a ceiling requires special ceiling brackets (sold separately) and specialized knowledge.
Improper mounting could cause the projector to fall, resulting in an accident.
•If the projector is ceiling-mounted, install the breaker for turning off the power in case of anomaly. Let
everyone involved with the use of the projector know that fact.

Note
•The projector consumes about 6W of power in standby. We recommend that you unplug
the power cord or turn off the main power switch if you will not be using the projector for
an extended period.
PRECAUTION
•If the power cord is unplugged before cooling is complete, give the lamp time (about 5
minutes) to cool before plugging it back in. If the lamp overheats, it may fail to light, and
its lifetime will be shortened.

 CAUTION
•Do not look into the lens while the lamp is on.  The strong light from the lamp may cause
damage to your eyes or sight.
•Do not block the air intake or exhaust. Doing so could cause a fire due to internal overheating.
•Do not place your hands, face, or other objects near the air exhaust. Doing so could cause
burns, deform/break the object.■ Removing the lens cover

Adjusting the volume with the 
 
 buttons
The speaker volume can be adjusted when an audio signal is being input.Notes
•Note that a lamp characteristics may rarely cause the brightness to fluctuate slightly.
•A lamp is consumable item. If used for extended periods, images will appear dark, and
the lamp could burn out.  This is characteristic of a lamp, and is not malfunction. (The
lifetime of the lamp depends on conditions of use.)
•The DMD
TM is made using extremely advanced technology, but there may be black spots
(pixels that do not light) or bright spots (pixels that are constantly lit) on the panel.  Please
note that these are not malfunctions.
•Although this projector supports a wide range of RGB signals 
p.45
, any resolutions not
supported by this projector (SVGA) will be expanded or shrunk, which will affect image
quality slightly. To view high-quality images, it is recommended that the computer’s
external output should be set to SVGA (800 × 600) resolution.
•With some models of computer having LCD displays or the like, displaying images
simultaneously on the projector and the monitor’s display may prevent the images from
displaying properly. If this happens, turn off the computer’s LCD display. For information
on how to turn off the LCD display, see the owner’s manual of your computer.
•If a signal not supported by the projector is input, the “Unsupported signal” will appear.
•If no signal is being input from the connected device, the “No signal” will appear.
•If an unavailable operation button is pressed, the 
 icon will appear.

Using the document cameraPlease read this chapter if the model you purchased is TDP-S21 which includes a document camera.■How to use the document camera
Using the camera attached on the projector
PRECAUTIONS
•For camera interconnection, be sure to use the supplied RGB cable (25 cm or 3 m). If you
use the other cables, the normal operation may not be achieved and even the malfunction
may result.
•When moving the projector with the camera attached, do not grab the camera arm and/or
the camera head.
•When moving the projector with the camera attached, first ensure that the camera is securely
locked in position on the tray
.
•Insert the RGB cable straight and securely until it is fixed in place.
•Do not jolt or force the camera head or camera arm. Doing so could cause malfunction.
•Note that when extending or rotating the camera arm, the arm moves in an arc. Take care
not to bump yourself or others with it.
•When placing the projector in the carrying bag, remove the connection cables. Otherwise,
damage to the connectors and cables may result.
Status before preparation

Notes
•There is no audio output when camera input is selected.
•If the room’s fluorescent lighting causes the image to flicker, either turn off the fluorescent
light, or set the Shutter from the Image adjustment menu

. Note that changing the
Shutter setting may not eliminate the flicker, depending on the lighting, state of the
document, or image adjustment.
■Locking the white balance
Although the projector’s camera is constantly adjusting the color balance of the images
it photographs, the color balance may be disrupted, depending on the color layout of
the document. If this happens, the white balance can be locked using the procedures
below.
1
Lay down a piece of white paper, and adjust so it fills the screen.Adjust the camera head and arm so that the white
paper fills the screen completely.
2
Set the White balance to Lock in the Image adjustment menu.
