Setting up
Connecting your devices (continued)
• Be sure to read the manuals for devices before connecting them to the projector, 
and make sure that all the devices are suitable to be connected with this product. Before 
connecting to a PC, check the signal level, the signal timing, and the resolution.
-  Be sure to consult to the administrator of the network. Do not connect LAN port to any 
network that might have the excessive voltage.
- Some signal may need an adapter to input this projector.
-  Some PCs have multiple screen display modes that may include some signals which 
are not supported by this projector.
-  
Although the projector can display signals with resolution up to WUXGA (1920X1200), the signal will 
be converted to the projector’s panel resolution before being displayed. The best display performance 
will be achieved if the resolutions of the input signal and the projector panel are identical.
• While connecting, make sure that the shape of the cable's connector fits the port to 
connect with. And be sure to tighten the screws on connectors with screws.
• When connecting a laptop PC to the projector, be sure to activate the PC’s external 
RGB output. (Set the laptop PC 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 PC.
• When the picture 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.
• In some cases, this projector may not display a proper picture or display any picture on 
screen. For example, automatic adjustment may not function correctly with some input 
signals. An input signal of composite sync or sync on G may confuse this projector, so 
the projector may not display a proper picture.
• 
The HDMI port of this model is compatible with HDCP (High-bandwidth Digital Content Protection) 
and therefore capable of displaying a video signal from HDCP compatible DVD players or the like.
NOTE
About Plug-and-Play capability

equipment (i.e. display devices). This projector is VESA DDC 2B compatible. Plug-and-
Play can be used by connecting this projector to a computer that is VESA DDC (display 
data channel) compatible.
• 
Take advantage of this feature by connecting an RGB cable to the RGB1 port (DDC 2B 
compatible). Plug-and-Play may not work properly if any other type of connection is attempted.
• Please use the standard drivers in your computer as this projector is a Plug-and-Play monitor.
NOTE for HDMI
• The HDMI supports the following signals.
  -Video signal : 480i@60,480p@60,576i@50,720p@50/60,1080i@50/60,1080p@50/60
  -PC signals : See User’s Manual (detailed) Technical
  -Audio signal :  Format    Linear PCM 
Sampling Frequency   48kHz / 44.1kHz / 32kHz
• This projector can be connected with another equipment that has HDMI or DVI 
connector, but with some equipment the projector may not work properly, something like 
no video or no audio.
•  Be sure to use an HDMI cable that has the HDMI logo.
• 
When the projector is connected with a device having DVI connector, use a DVI to HDMI cable 
to connect with the HDMI input and an audio cable to connect with one of the AUDIO input.

About the remote control signal 
 
The remote control works with the projector’s remote sensors. This projector has 
three remote sensors on the front, on the top, and on the back.
   
The sensors can be respectively turned active or inactive using the “REMOTE 
RECEIV.” in the SERVICE item of OPTION Menu ( 
  51 ). Each sensor senses the 
signal within the following range when the sensor is active. 
   
The front and top sensors:
   
 
60 degrees (30 degrees to the left and right of the 
sensor) within 3 meters about. 
   
The back sensor:
   
 
40 degrees (20 degrees to the left and right of the 
sensor) within 3 meters about. 
  • The remote control signal refl ected in 
the screen or the like may be available. If it is 
diffi cult to send the signal to the sensor directly, 
attempt to make the signal refl ect.
   
• The remote control uses infrared light to send 
signals to the projector (Class 1 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.
   
• The remote control may not work correctly if 
strong light (such as direct sun light) or light 
from an extremely close range (such as from 
an inverter fl uorescent lamp) shines on the 
remote sensor of the projector. Adjust the 
position of projector avoiding those lights.    NOTE 
 
Changing the frequency of  remote control signal 
 
The accessory remote control has the choice of 
the mode 1 or the mode 2, in the frequency of 
its signal. If the remote control does not function 
properly, attempt to change the signal frequency.
   
Please remember that the “REMOTE FREQ.” in 
SERVICE item of OPTION Menu ( 
  51 ) of the 
projector to be controlled should be set to the 
same mode as the remote control.
   
To set the mode of the remote control, slide the 
knob of the frequency switch inside the battery 
cover into the position indicated by the mode 
number to choose.
