the projector might crash down, overturn, smash your fingers and possibly 
result in malfunction. To prevent damaging the projector and injuring yourself, 
always hold the projector whenever using the elevator buttons to adjust the 
elevator feet.

backward or forward exceeding 9 degrees. Exceeding these range could cause 
malfunction, and could shorten the lifetime of the consumables.
►Except for inclining by the elevator feet adjustment, place the projector 
horizontally.
You can use the elevator feet to make adjustments if the surface on which you 
need to set the projector is uneven or if you otherwise need to adjust the angle of 
projection. The adjustment range of the elevator feet is 0 to 9 degrees.

elevator buttons  while holding the projector. 
   The elevator buttons and the elevator feet are on the both sides.
2. Raise or lower the projector to the desired height and release the elevator 
buttons.  
   When you release the elevator buttons, the elevator feet will lock into position.

CAUTION  ►Turn off all devices prior to connecting them to the projector. 
Attempting to connect a live device to the projector may generate extremely 
loud noises or other abnormalities that may result in malfunction and/or damage 
to the device and/or projector.
►Use the accessory cable or a designated-type cable for the connection. 
Some cables have to be used with core set. A too long cable may cause a 
certain picture degradation. Please consult with your dealer for details. For 
cables that have a core only at one end, connect the core to the projector .
►Make sure that you connect devices to the correct port. Incorrect connection 
may result in malfunction and/or damage to the device and/or projector . 
NOTE  • Whenever attempting to connect a laptop computer to the projector, be sure 
to activate the laptop’s RGB external image output (set the laptop to CRT display or to 
simultaneous LCD and CRT display). For details on how this is done, please refer 
to the 
instruction manual of the corresponding laptop computer.
• Secure the screws on the connectors and tighten.
• Some computers may have multiple display screen modes. Use of some of these 
modes will not be possible with this projector.
• For some RGB signal modes, the optional M ac adapter is necessary.
• When the image resolution is changed on a computer, depending on an input, 
automatic adjustment function may take some time and may not be completed. In this 
case, you may not be able to see a check box to select “Yes/No” for the new resolution 
on Windows. Then the resolution will go back to the original. It might be recommended 
to use other CRT or LCD monitors to change the resolution.

Using the remote control
CAUTION  ►Be careful in handling the remote control.
• Do not drop or expose the remote control to physical impact.
• Do not get the remote control wet or place it on wet objects. It may result in 
malfunction.
• Remove the batteries from the remote control and store them in a safe place if 
you won’t be using the remote control for an extended period. 
• Replace the batteries whenever the remote control starts malfunctioning. 
• When strong lights (such as direct sunlight) or light from an extremely close 
range (such as from an inverter fluorescent lamp), hit the projector’s remote 
sensor, the remote control may cause to function. Adjust the direction of the 
projector to keep the light from directly hitting the projector’s remote sensor.
The remote control works with the projector’s remote sensor.
• The range of the remote sensor is 3 meters with a 60 degree range (30 degrees 
to the left and right of the remote sensor).
• Also  a  remote  signal  reflected  in  the  screen  etc.  may  be  available.  If  it  is  difficult 
to send a remote signal to the sensor directly, please try to use the reflected signal.
•  Since  the  remote  control  uses  infrared  light  to  send  signals  to  the  projector 
(Class1  LED),  be  sure  to  use  the  remote  control  in  an  area  free  from  obstacles 
that could block the remote control’s output signal to the projector.
