This device is restricted to indoor use when operated in the 5.15 to 5.35 GHz
frequency range (Channels 36 to 64).
Art-Net
“Art-Net” is an Ethernet communication protocol based on the TCP/IP protocol.
By using the DMX controller and the application software, illumination and stage system can be controlled. Art-Net
is made based on DMX512 communication protocol.
Cautions on use
r
To get a good picture quality
f
In order to view a beautiful image in higher contrast, prepare an appropriate environment. Draw curtains or
blinds over windows and turn off any lights near the projection surface to prevent outside light or light from
indoor lamps from shining onto the projection surface.
f
The projection lens of the projector is thermally affected by the light from the light source, making the focus
unstable in the period just after switching on the power. The focus will stabilize after projection for more than 30
minutes has elapsed.
r
Do not touch the surface of the projection lens with your bare hands.
The finger print or dirt on the projection lens surface may be projected enlarged to the projection surface.
r
DLP chips
f
The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always
lit. Note that such phenomenon does not indicate malfunction.
f
Directing a high-power laser beam onto the projection lens surface can damage the DLP chip.
r
Light source
Laser is used as the light source of the projector, and it has the following characteristics.
f
The luminance of the light source will decrease by duration of usage.
When the light source is used for approximately 20 000 hours, its luminance is reduced to half its initial
luminance. 20 000 hours is the estimated duration, and it varies depending on individual differences and usage
conditions.
If the light source goes off or the brightness reduces noticeably, ask your dealer about replacement of the light
source unit.
r
Computer and external device connections
When connecting a computer or an external device, read related section of this document including the use of
power cords and shielded cables.
Storage
If you store the projector, please keep it in a dry room.
Disposal
To dispose of the product, ask your local authorities or dealer for correct methods of disposal. Also, dispose of the
product without disassembling.
