r
Do not touch the surface of the projection lens with your bare hands.
If the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified and
projected onto the screen.
Attach the supplied lens cover to the optional projection lens when not using the projector.

DLP chips
f
The DLP chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always
lit. Such a phenomenon does not indicate malfunction.
f
Directing a high-power laser beam onto the projection lens surface can damage the DLP chips.
r
Do not move the projector or subject it to vibration or impact while it is operating.
Doing so may shorten the life of the built-in motor.

devices) which are suitable for your 3D system. Connections of the projector and external devices vary depends
on the 3D system to be used, see the operating instructions of external devices you use.
