product without disassembling.
Cautions on use
r
To get a good picture quality
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 screen to prevent outside light or light from indoor lamps from
shining onto the screen.
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 lens cover supplied with the projector or with the optional projection lens to the projector when you do
not use the projector.
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. 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.
r
Light source
The light source of the projector uses laser diode, and has the following characteristics.
f
Depending on the operating environment temperature, the luminance of the light source will decrease.
The higher the temperature becomes, the more the luminance of the light source decreases.
f
The luminance of the light source will decrease by duration of usage.
If brightness is noticeably reduced and the light source does not turn on, ask your dealer to clean inside the
projector or replace the light source unit.
r
Computer and external device connections
When connecting a computer or an external device, read this manual carefully regarding the use of power cords
and shielded cables as well.
