connector securely into the projector.Connect the other end of the power cable to an 
earthed electrical outlet.
The Power indicator will light orange.
CAUTION
Be sure to read the separate Safety Instructions/World-Wide Warranty 
Terms before projecting images.
TIP
When the Extended - Operation - Direct Power ON menu item 
is set to ON, a confirmation buzzer sounds and the projectors 
power turns on as soon as the power plug is inserted into the electrical 
outlet, and projection then starts. sp.62
The power for the equipment that is connected to the projector should

TIP
 If only one signal source has been connected, the signals from that 
source will be projected without needing to press any of the buttons 
on the remote control or the projectors control panel.
 If the No Signal. message does not disappear, check the 
connections again.
 If a laptop computer or a computer with an LCD screen has been 
connected to the projector, the images may not be projected straight 
away. After starting projection, check that the computer has been set 
up to output signals externally.
The following table shows examples of how to toggle output settings. 
For details, refer to the section of the documentation provided with 
your computer under a heading such as External output, 
Connecting an external monitor or similar.
 If the same still picture is projected for a long period of time, the 
projected image may become burned into the screen. You should 
avoid leaving the same image displayed for long periods.

Turning the Projector Off
If not using the projector for a long period, unplug the 
power cable from the electrical outlet.Attach the lens cover.
Attach the lens cover to the lens when not using the projector, 
in order to prevent the lens from getting dusty or dirty.TIP
 If the Power indicator is flashing orange, operation of the [Power] 
buttons is disabled. Wait until the indicator lights continuously.
 If Standby Mode in the configuration menu is set to Network 
ON, fans will continue operating. This is normal and does not 
indicate a problem.4
CAUTION

Adjusting the Screen ImageThese functions correct and adjust the projected images so that optimum 
images can be obtained.Adjusting the Image Size (Zoom Function)
The size of the projected image is basically determined by the distance 
from the projector to the screen. sp.16
The following procedures explain how to adjust the screen image once the 
projector itself has been set up.PROCEDUREAdjust by turning the zoom ring.
The maximum zoom ratio of the EMP-821 is × 1.6, and that of the 
EMP-81/61 is × 1.2.
If you would like to enlarge the image further, move the projector 
further away from the screen. sp.16
Focusing the Screen Image
PROCEDURETurn the focus ring to adjust the image focus.
If keystone correction or Sharpness settings have been made, it may 
not be possible to adjust the focus correctly.
TIP
The E-Zoom function lets you enlarge parts of the image. sp.48
Turn to W (wide) to 
enlarge the images.
Zoom ring Turn to T (tele) to 
reduce the images.
Focus ring
TIP
 If the surface of the lens is dirty or misted over as a result of 
condensation, it may not be possible to adjust the focus correctly. 
If this happens, clean or de-mist the lens. sp.77, p.84
 If the distance from the lens to the screen is not within the 
recommended distance, it is impossible to bring the lens into focus.If you have trouble obtaining the correct focus, check the 
projection distance.

Adjusting the Screen ImageAdjusting the Image Angle and Automatic Keystone Correction Function
The projector should be set up so that it is as perpendicular to the screen as 
possible.If it is not possible to set up the projector so that it is perpendicular to the 
screen, it can be set up at a slight vertical angle instead. You can adjust the 
upward projection angle of the projector to a maximum of 12° and the 
downward projection angle to a maximum of 4° by extending and 
retracting the front adjustable foot and rear adjustable feet.Seen from the side

CAUTION
Do not tilt the projector at more than the maximum angle. Doing so 
may cause the projector to fall down or fall off a desk and may result 
in injury. 
						

							38
Adjusting the Screen Image
PROCEDUREWhile pulling the foot adjust lever at the front of the 
projector, lift up the front of the projector to extend the 
front adjustable foot.
Extend the front adjustable foot until the desired angle is obtained, 
and then release the foot adjust lever.
To retract the front adjustable foot, gently push down on the projector 
while pulling the foot adjust lever.
When the projector is tilted vertically, it will cause keystone distortion to 
appear in the image. However, the projector is equipped with an automatic 
keystone correction function that can automatically correct this keystone 
distortion as long as the vertical angle of tilt is within a range of 
approximately 15º *. Automatic keystone correction is carried out 
approximately one second after the projector is tilted vertically while the 
power is on.
* This value applies when the zoom ring is turned to the maximum T 
setting. If the zoom ring is turned to the W setting, the available angle 
of tilt for automatic adjustment will be less.
Foot adjust lever (Front)
TIP
If the projector is tilted vertically or horizontally, turn the bases of the 
rear adjustable feet to make fine adjustments to the height of the 
projector. When the projector is tilted horizontally, the correction may 
not be carried out correctly. sp.38
Extend Retract Rear 
adjustable foot
TIP
 Automatic keystone correction is not carried out when the 
Projection command in the Extended menu is set to Front.
 If you would like to make further fine adjustments after automatic 
keystone correction has been carried out, press the [ ] and [ ] 
buttons on the projectors control panel. sp.39
 When keystone correction is carried out, the projected image will 
become smaller.
 If the images become uneven in appearance after keystone correction 
is carried out, decrease the sharpness setting. sp.51, p.53
 If automatic keystone correction is not required, set Auto 
Keystone in the Setting menu to OFF. sp.59 
						

							39
Adjusting the Screen ImageManually Correcting Keystone Distortion
The projector is provided with an automatic keystone correction function 
which detects the vertical angle of the projector and carries out keystone 
correction automatically. If you would like to make further fine 
adjustments to the results of automatic keystone correction, press the [ ] 
and [ ] buttons. PROCEDURE
Projector Projector If the bottom of the 
image is elongatedIf the top of the 
image is elongated
TIP
 When keystone correction is carried out, the projected image will 
become smaller.
 If the text part of the image is blurred after keystone correction is 
carried out, decrease the sharpness setting. sp.51, p.53
 Keystone correction can also be carried out using the configuration 
menu. sp.59
 If the value displayed in the gauge on the screen stops changing 
when keystone correction is being carried out, it indicates that the 
limit for keystone correction has been reached. Check that the 
projector has not been set up at an angle which exceeds the proper 
limit.
