Plug-and-Play Capability
Plug-and-Play is a system incorporated in the computer, its operating system and 
peripheral equipment (i.e. display devices).
This projector is compatible with VESA DDC 1/2B. Plug-and-Play can be achieved by 
connecting this projector to computers that are VESA DDC (display data channel) 
compatible.
• Please take advantage of this function by connecting the accessory RGB cable to the 
RGB port (DDC 1/2B compatible). Plug-and-Play may no t work properly if any other 
type of connection is attempted.

projector. You can see the ports.
 WA R N I N G
• Whenever attempting to connect other devices to the projector, read thoroughly the 
“Quick Start Guide”, this manual and the manual of each device to be connected. 
Incorrect connections could result in fire or electrical shock.
 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.
 ATTENTION
• 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. Refer to the section 
“Technical” of this manual for the pin assignment of connectors and RS-232C 
communication data.
• Some cables may have to be used with core set. Use the accessory cable or a 
designated-type cable for the connection. For cables that have a core only at one end, 
connect the core to the projector.
• Secure the screws on the connectors and tighten.
• 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.

Operating The Remote Control
NOTE
• Replace the batteries whenever the remote control starts to malfunction.
• 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 cease to function. Adjust the direction of the projector to keep light from 
directly hitting the projector’s remote sensor.
The remote control works with the 
projector’s remote sensors.
Front remote sensor is 3 meters with a 
60 degree range (30 degrees to the left 
and right of a remote sensor).
Rear remote sensor is 3 meters with a 4 
degree range (2 degrees to the left and 
right of a 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 pointing it at a different angle.
Since the remote control uses infrared light to send signals to the projector (Class 1 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.
memo You can use the remote control as a wired remote control, by connecting the REMOTE 
CONTROL port of the main unit and remote control via an audio cable (3.5 dia. Stereo mini 
cable with plugs).
Using The Remote ID Feature
This is the function to be used when you operate two or three projectors of 
the same type simultaneously. This function should be used combining a 
setup of a projector.

REMOTE ID” of the section “OPTION Menu”.
memo When the ALL is selected to the item “IR REMOTE ID” of the 
OPTION menu, the projector is controlled by a remote control 
irrespective of the position of the ID CHANGE switch.
2Slide the knob of the switch into the position of the ID number of the 
projector you want to control.
 CAUTION
• Do not disassemble the remote control.
• Do not place the remote control near the projector’s lens, fan, or vents.
