On repacking
Save the original shipping carton and packing material;
they will come in handy if you ever have to ship your unit.
For maximum protection, repack your unit as it was
originally packed at the factory.
On “stuck” pixels on an LCD screen
The LCD panel fitted to this unit is manufactured with high
precision technology. Thus a very small proportion of
pixels may be “stuck,” either always off (black), always on
(red, green, or blue), or flashing. In addition, over a long
period of use, because of the physical characteristics of the
liquid crystal display, such “stuck” pixels may appear
spontaneously. These problems are not a malfunction.
On prohibiting continuous lighting
Continuously lighting the Xenon lamp for 24 hours will
reduce approximately half of its lamp life. Be sure to turn
off the lamp for an hour or more after continuously lighting
for 24 hours.
On dangerous areas in a case of lamp
explosion
Since a projector lamp can explode, it is dangerous to be in
the shaded areas shown in the illustrations below. Keep
away from the dangerous areas.
The danger radius (x) differs depending on the height (y)
between the bottom of the projector and the floor.
For example, in a case where the height (y) is 800 mm
(31
1
/
2
in.), the danger radius (x) calculated by the formula
above is 800 mm (31
1
/
2
in.)
