Safety Instructions (Continued)
10. Do not attempt to
disassemble this projector.
There are dangerous high
voltages inside which may
cause death if you should
come into contact with live
parts. The only user
serviceable part is the lamp
which has its own removable
cover.
Under no circumstances
should you ever undo or
remove any other covers.
Refer servicing only to suitably
qualified professional service
personnel.
11. When the projector is under
operation, you may sense
some heated air and odor
from its ventilation grill. It is a
normal phenomenon and not
a product defect.
