J
Operating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke
will reduce the service life of the optical components and may necessitate their replacement within less than
one year of use. For details, consult your dealer.
Lamp
J
The luminous source of the projector is a mercury lamp with high internal pressure.
A high pressure mercury lamp has following characteristics.
The brightness of the lamp will decrease by duration of usage.
z
The lamp may burst with sound or shorten life by shock or chipping.
z
The life of the lamp varies greatly depending on individual specicities and usage conditions. In particular,
z
continuous use over 22 hours and frequent on/off switching of the power greatly deteriorate the lamp and
affect the lamp life.
In rare cases, the lamp burst shortly after the projection.
z
The risk of bursting increases when the lamp is used beyond its replacement cycle. Make sure to replace
z
the lamp unit consistently. (Æ page 56)
If the lamp bursts, gas contained inside of the lamp is released in a form of smoke.
z
It is recommended to store replacement lamps for contingency.
z
It is recommended to have authorized engineer or your dealer replace the lamp unit.
