The adjustment range of the elevator feet is 0 to 7 degrees.
1.Press and hold in the elevator 
buttons while holding the projector. 
There are elevator buttons and feet 
on the both sides of the projector.
2.Raise or lower the projector to the 
desired height and release the 
elevator buttons. When the elevator 
buttons are released, the elevator 
feet will lock into position.
3.If necessary, the elevator feet can 
be manually twisted to make more 
precise adjustments.
► Do not adjust the elevation of the projector during or 
immediately after use. Handling while the projector is hot could cause burn 
and/or projector malfunction. Before adjusting the elevation, make sure that the 
power switch is off, that the power cord is unplugged, and that the projector is 
adequately cool.
WARNING
► Using the elevator buttons without holding the projector could 
cause the projector to fall, overturn, or strike your fingers and possibly cause 
projector malfunction. To prevent damaging the projector and injuring yourself, 
always hold the projector whenever using the elevator buttons to adjust the 
elevator feet.
► Do not tilt the projector to the right or left. Also be sure not to raise the 
front or rear of the projector more than 7 degrees. Raising the projector more 
than 7 degrees could cause projector malfunction or shorten the lifetime of 
consumables.
► Other than raising the projector using the elevator feet, place the projector 
horizontally. CAUTION

• Full-size display may not be possible with some input signals. Refer 
to the resolutions above.
• Although the projector can display signals with resolution up to SXGA 
(1280x1024), signals will be converted to the projector’s panel resolution 
before being displayed. The best display performance is achieved when the 
resolutions of the input signal and projector panel are identical.
• For some input types when the screen resolution is changed on a computer , 
the automatic adjustment function may take a long time or may not complete. If 
this happens, you may not be able to see the “Yes/No” check box to confirm the 
resolution change in Windows. The screen resolution will then be reset to the 
previous resolution. It is recommended to use a CRT or LCD monitor to change 
the resolution if this occurs. NOTE

Using the remote control
The remote control works with the 
projector’s remote sensor.
  The range of the remote sensor is 
60-degrees (30-degrees to the left and 
right of the remote sensor) within 3 
meters.
  The remote signal may also be able to be reflected off the screen etc. If it 
is difficult to send the remote signal 
to the sensor directly, try to reflect the 
signal.
  The remote control uses infrared light to send signals to the projector (Class1 
LED), so be sure to use the remote control in an area free from obstacles that 
could block the remote control’s signal to the projector.
Using the remote control button lights
When using the remote control in the dark, the buttons of the 
remote control can light up.
1.Pressing the LIGHT button turns the remote control 
button lights on. The lights will automatically turn off after 
a short time.
► Be careful when handling the remote control. Incorrect 
handling could cause damage and/or malfunction.
• Do not drop, hit or otherwise jar the remote control in anyway .
• Do not get the remote control wet or place it on wet objects.
• If you will not use the remote control for an extended period, remove the 
batteries from the remote control and store them in a safe place.CAUTION
• If the remote control starts to malfunction, replace the batteries.
• The remote control may not function correctly if strong light (such as direct 
sunlight) or light from an extremely close range (such as from an inverter 
fluorescent lamp) shines on the projector’s remote sensor. Adjust the position 
of the projector so that light does not shine directly on the projector's remote 
sensor. NOTE
