Preparation
Preparation for projection 1. Attach the provided power cord to the projector. 
2. Plug the power cord in the wall outlet. 
3. Remove the lens cap. 
Warning:  Do not look into the lens directly when the projector is on. 
 The lens cap is for protecting the lens. If you leave the lens cap on 
the lens with the projector turned on, it may be deformed because 
of heat build-up. Remove the lens cap when you turn on the pro-
jector. 
 The power cords for use in the U.S. and Europe are provided with 
this projector. Use the appropriate cord for your country. 
 This projector uses the power plug of three-pin grounding type. Do 
not remove the grounding pin from the power plug. If the power 
plug doesn’t fit your wall outlet, ask an electrician to change the 
wall outlet. 
 The provided power cord for the U.S. is rated at 120 V. Never con-
nect this cord to any outlet or power supply using other voltages or 
frequencies than rated. If you want to use a power supply using 
other voltage than rated, prepare an appropriate power cord sepa-
rately. 
 Use 100-240 V AC 50/60 Hz to prevent fire or electric shock. 
 Do not place any objects on the power cord or do not place the 
projector near heat sources to prevent damage to the power cord. 
If the power cord should be damaged, contact your dealer for 
replacement because it may cause fire or electric shock. 
 Do not modify or alter the power cord. If the power cord is modified 
or altered, it may cause fire or electric shock. 
Caution:  Plug in the power cord firmly. When unplugging, hold and pull the 
power plug, not the power cord. 
 Do not plug in or out the power cord with your hand wet. It may 
cause electric shock. 
Adjustment of the projection angle For the best projection, project images on a flat screen installed at 90 
degrees to the floor. If necessary, tilt the projector using the two 
adjustment feet on the bottom of the projector.
 1. Tilt up the project to the appropriate angle. 
2. Press the foot adjustment buttons next to the adjustment feet 
(rear), and the adjustment feet will come out. 
3. Release the buttons to lock the adjustment feet (rear) to that 
position. 
4. Rotate the adjustment feet (rear) for fine adjustment. 
After using the projector: 
5. Put the adjustment feet (rear) back into the projector by pressing 
the foot adjustment buttons. 
Important:  If necessary, rotate the adjustment feet (front) for fine adjustment. 
 Install the screen on a flat wall at 90 degrees to the floor. 
 Slanting the projector more than ±10° (right and left) or ±15° (front 
and rear) may cause trouble or explosion of the lamp. You can tilt 
the projector up to 7 degrees using the adjustment feet only. 
 Images may not be projected in a shape of a regular rectangle or 
with its aspect ratio 4:3, depending on the installation conditions of 
the projector and the screen. 
 To correct vertical keystone distortion, press the KEYSTONE but-
ton on the projector or the remote control to display KEYSTONE, 
and adjust the image by pressing the S, T button (or VOLUME +, 
- button on the remote control). 
In the following cases:  
Important: 
 When the keystone adjustment is carried out, the adjustment 
value is indicated. Note that this value doesn’t mean a projection 
angle. 
 The allowable range of the adjustment value in the keystone 
adjustment varies depending on the installation conditions. 
 When the keystone adjustment takes effect, the resolution 
decreases. In addition, stripes may appear or straight lines may 
bend in images with complicated patterns. They are not due to 
product malfunctions. 
 Noise may appear on the screen during the keystone adjustment 
because of the type of the video signal being projected and the 
setting values of the keystone adjustment. In such cases, set the 
keystone adjustment values in the range where the image is dis-
played without noise. 
 When the keystone adjustment is carried out, the image may not 
be displayed correctly because of the type of input signal.
 Keystone correction is not available when selecting Squeeze ON 
or selecting 16:9 mode by Remote unit.
For SD205U/SD205R only 
 When the 720p or 1080i signal is input, the keystone adjustment 
ranges are limited.

Basic operation
Power-on 1. Turn on the device connected to the projector first. 
2. Plug the power cord in the wall outlet. 
 The POWER indicator lights up. 
 If the power cord is unplugged from the wall outlet before the

and the POWER button may not function. In this case, wait 
for the fans to stop and press the POWER button to light the 
indicator. 
3. Press the POWER button on the control panel or the ON button 
on the remote control. 
 It may take about one minute for the lamp to light up. 
 The lamp occasionally fails to light up. Wait a few minutes 
and try to light the lamp again. 
 After the POWER button is pressed, the image may flicker 
before the lamp becomes stable. This is not a product mal-
function. 
 Regardless of the setting of LAMP MODE in the INSTALLA-
TION menu, the STANDARD lamp mode is activated by 
default whenever the projector is turned on. When LAMP 
MODE has been set to LOW, the lamp mode changes from 
STANDARD to LOW about one minute after turn-on. 
Important:  Do not cover the lens with the lens cap while the lamp is on. Do 
not strip off the aluminum sheet inside the lens cap.
 The projector starts warming up when the POWER button is 
pressed. During the warm-up process, images may appear dark 
and no commands are accepted. 
 By blinking red, the STATUS indicator indicates that the lamp 
should be replaced soon. Replace the lamp when the STATUS 
indicator blinks red. (See page 23 and 26.) 
 Images may not be projected with good quality in an extremely hot 
or cold environment. (This is not a product malfunction.)

 If the power cord should be unplugged accidentally while 
either the air inlet fan or the air outlet fans are operating or 
the lamp is on, allow the projector to cool down for 10 min-
utes with the power off. To light the lamp again, press the 
POWER button (or OFF button). If the lamp doesn’t light up 
immediately, repeat pressing the POWER button (or OFF 
button) two or three times. If it should still fail to light up, 
replace the lamp.

displaying 4:3 image, the afterimages of the black bars may 
appear on the 4:3 image screen. Consult your dealer in this case.
 This function doesnt work when using Keystone correction.
Caution:  After using the projector, wait one minute for the air outlet fans to 
stop. Then unplug the power cord from the wall outlet. 
 The lamp can’t be lit again for one minute after turned off for safety 
purpose. It will take another one minute for the STATUS indicator 
to go out. If you want to turn on the projector again, wait until the 
indicator goes out, and then press the POWER button. 
 The air outlet fans rotate faster as the temperature around the pro-
jector rises. 
 When the temperature around the projector rises high, the sign
