Lamp replacement (continued)
B)When the projector is mounted to
the ceiling
When removing the lamp unit from the projector
mounted to the ceiling, never fail to use the lamp
replacement attachment to protect yourself from glass
fragments and so on.
In case that you pull a lamp out without using a lamp
replacement attachment for some reason, such as to
check the lamp, please dismount the projector from
ceiling mounting holder to start the procedure with
projector put on the table for safety reasons.
When you have to execute the procedure without
dismounting the projector from ceiling mounting holder
as well as without using a lamp replacement
attachment, please make sure that you take appropriate
safety measure, such as wearing protective glasses and
mask, and that no one is around before you start the
procedure.
Avoid executing the procedure right under the
projector, especially around the lamp cover, for fear
that glass debris might fall.
IF YOU GET GLASS DEBRIS IN THE EYE OR MOUTH,
CALL A PHYSICIAN.
