Connecting Your Devices

WARNING • Incorrect connecting could result in fire or electrical shock.
Whenever attempting to connect other devices to the projector, please thoroughly read
the "User's Manual - Safety Guide", this manual and the manual of each device to be
connected.

CAUTION

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

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 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.

• TURN OFF ALL DEVICES prior to connecting them to the projector.

• Make sure that you connect devices to the correct port. Incorrect

NOTE

• 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 COMPUTER port (DDC 1/2B compatible). Plug-and-Play may not work
properly if any other type of connection is attempted.

• Plug-and-Play is a system composed of the computer, its operating system and
peripheral equipment (i.e. display devices).

• Please use the standard drivers in your computer as this projector is a Plug-and-Play
monitor.

NOTE

these modes will not be possible with this projector.

• For some COMPUTER input modes, the optional Mac adapter is necessary.

• When the image resolution is changed on a computer, depending on an input,

automatic adjust 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 TFT monitors to change the resolution.

Putting Batteries

CAUTION Always handle the batteries with care and use them only as directed.
Improper use may result in battery cracking or leakage, which could result in fire, injury
and/or pollution of the surrounding environment.

• Keep the battery away from children and pets.

• Be sure to use only the batteries specified for use with the remote control. Do not mix

new batteries with used ones.

• When inserting batteries, verify that the plus and minus terminals are aligned correctly
(as indicated in the remote control).

• When you dispose the battery, you should obey the law in the relative area or country.

Remote Control (continued)

Operating The Remote Control

ATTENTION • Do not drop or otherwise expose the remote control to physical
impact.

• Do not get the remote control wet or place it on wet objects. Doing so 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 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 cause 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
sensor.

• The range of the remote sensor is 3 meters with a 60­degree 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.

• 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.
