Battery installation
1
Push and slide to open the lid, then install the two
size AA (R6) batteries (supplied) with the correct
polarity.
Be sure to
install the
battery from
the # side.
2
Replace the lid.
Notes on batteries
• Make sure that the battery orientation is correct when
inserting batteries.
• Do not mix an old battery with a new one, or
different types of batteries.
• If you will not use the Remote Commander for a
long time, remove the batteries to avoid damage
from battery leakage. If batteries have leaked,
remove them, wipe the battery compartment dry and
replace the batteries with new ones.
Notes on Remote Commander operation
• Make sure that there is nothing to obstruct the
infrared beam between the Remote Commander and
the remote control detector on the projector.
• The operation range is limited. The shorter the
distance between the Remote Commander and the
projector is, the wider the angle within which the
commander can control the projector.

Notes
• This unit accepts the VGA, SVGA, XGA or SXGA
signals. However, we recommend you to set the
output signal of your computer to the XGA.
• If you set your computer, such as a notebook type
IBM PC/AT compatible, to output the signal to both
the display of your computer and the external
monitor, the picture of the external monitor may not
appear properly. In such cases, set the output mode
of your computer to output the signal to only the
external monitor.
For details, refer to the operating instructions supplied
with your computer.
• The RGB input connectors of the INPUT A/B and
DIGITAL RGB connector of the INPUT A comply
with the VESA DDC2B. If your computer or
graphics board is compatible with DDC, turn on the
power of the equipment as follows:
1 Connect the projector to the computer with the HD
D-sub 15-pin cable.
2 Turn on the power of the projector.
3 Boot up the computer.
When making connections, be sure to:
• turn off all equipment before making any connections.
• use the proper cables for each connection.

Connecting
• insert the plugs of the cables properly; plugs that are
not fully inserted often generate noise. When pulling
out a cable, be sure to pull it out from the plug, not
the cable itself.
Notes
• Connect all the connecting cables to the INPUT A
connector when you input a signal from the INPUT
A connector.
Connect all the cables to the INPUT B connector
when you input a signal from the INPUT B
connector as well.
• Supplied mouse cables may not work properly
according to your computer.
