7.
The lamp becomes extremely hot
during operation. Allow the
projector to cool for
approximately 45 minutes prior
to removing the lamp assembly
for replacement.
8. Do not operate lamps beyond the
rated lamp life. Excessive
operation of lamps beyond the
rated life could cause them to
break on rare occasions.
9. Never replace the lamp assembly
or any electronic components
unless the projector is unplugged.
10. Do not place this product on an
unstable cart, stand, or table. The
product may fall, sustaining
serious damage.
11. 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.
Under no circumstances should
you ever undo or remove any
other covers. Refer servicing only
to suitably qualified professional
service personnel.
12. 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.
