Important Information
■
Do not move the projector while it is operating or subject it to vibration or
impact.
Doing so may shorten the service life of its internal components.
■
Lamp
The luminous source of the projector is a high-pressure mercury lamp.
A high-pressure mercury lamp has the following characteristics.
▶
z
The luminance of the lamp will decrease by duration of usage.
▶
z
The lamp may burst with a loud sound or have its service life shortened because of shock, chipping, or
degradation due to cumulative operating time.
▶
z
The lamp life varies greatly depending on individual differences and usage conditions. In particular,
frequent on/off switching of the power greatly deteriorate the lamp and affect the lamp life.
▶
z
Continuous use for over 1 week will deteriorate the lamp. The degradation of the lamp due to continuous
usage can be reduced by lamp relay function. (
page 104)
▶
z
In rare cases, the lamps burst shortly after projection starts.
▶
z
The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace
the lamp unit regularly.
(“When to replace the lamp unit” (
page 152), “Replacing the lamp unit” (

▶
z
If the lamp bursts, gas contained inside of the lamp is released in a form of smoke.
▶
z
It is recommended that you store replacement lamp units for contingency.

Viewing 3D video (PT-DZ21KU and PT-DS20KU only)
The projector can display 3D video signals that are input by the “simultaneous”, “frame packing method”,
and “side by side” methods. You are required to prepare external devices for viewing 3D video (such as 3D
Eyewear, video signal output devices) which are suitable for your 3D system. For connections of the projector
and external devices, see the instructions of external devices you use. Refer to “List of 3D compatible signals”
(
page 176) for the types of 3D video signals that can be used with the projector.
