15. 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.
