The lightning flash with arrowhead symbol, within an equilateral triangle, is intended
to alert the user to the presence of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude to constitute a risk of electric
shock.
The exclamation point within an equilateral triangle is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the litera-
ture accompanying the appliance.
WARNING:
TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
CAUTION:
TO PREVENT ELECTRIC SHOCK, DO NOT USE THIS (POLARIZED) PLUG WITH AN EXTENSION
CORD, RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO
PREVENT BLADE EXPOSURE.
NOTE:
SINCE THIS PROJECTOR IS PLUGGABLE EQUIPMENT, THE SOCKET-OUTLET SHALL BE IN-
STALLED NEAR THE EQUIPMENT AND SHALL BE EASILY ACCESSIBLE.
WARNING
Use the attached specified power supply cord. If you
use another power-supply cord, it may cause interfer-
ence with radio and television reception.
Use the attached RGB cable, RS-232C cable with this
equipment so as to keep interference within the limit
of a FCC Class A device.
This apparatus must be grounded.
The projector automatically shuts off when the

The electro-magnetic susceptibility has been chosen
at a level that gains proper operation in residential
areas, on business and light industrial premises and
on small-scale enterprises, inside as well as outside
of  the buildings. All places of operation are
characterised by their connection to the public low
voltage power supply system.

Basic connections
This projector can be connected to equipment such as VCRs, video cameras, videodisc players, and personal com-
puters having analog RGB output.
Important:
•Make sure that your equipment is turned off before connection.
•Plug in firmly and unplug by holding the plug, not by pulling the main power cable.
•If connected units are set too close to one another, the image may be affected.
•Refer to the owners guide of each component for details of connections.
Projector + AV equipment
Important:
•Match the color of video and audio plugs on the AV cable with the connections.
•S-video signals take priority over video signals. If you input both S-video signals and normal video signals at
the same time, the normal video input automatically is inhibited.

Connecting with HDTV decoder
Many HDTV decoders have HDTV system compo-
nent video output (Y, P
B, PR) terminal. When con-
necting the projector with this type of HDTV de-
coder, the COMPUTER INPUT in the SIGNAL
setting menu becomes [Y, P
B, PR] automatically.
•Y,  PB, PR is an example of the terminal names for a HDTV decoder.
•The terminal name is different depending on the connected equipment.
•Use mini D-SUB 15 pin-BNC conversion cable for connection.
•Some DVD players may not project the image correctly.
•When connecting with HDTV equipment which has R, G, B output, set RGB for the COMPUTER INPUT in the SIGNAL
setting menu.
