Projector features
This projector is used to project various computer signals as well as NTSC/PAL/
SECAM video signals onto a screen. It requires just a little space for installation 
and gets a large image from short distance.
 High Brightness
Newly developed 230W UHB (Ultra High Brightness) lamp gives you a higher 
brightness image on a screen. The image can be still kept as bright and clean 
enough for use in bright rooms.
 Low Noise
WHISPER mode is available for reducing acoustic noise to realize quieter 
operation. It is perfect for use in low luminance rooms where low noise is more 
important than brightness.
 Compact Body
Even with its many features, this projector is extremely compact and slim, 
which gives you more flexibility and usability to use it where you want.

Connecting your devices
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 Mac 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.
