The projector is grounded through the grounding conductor on the
power cord. To avoid electric shock, plug the power cord into a properly
wired receptacle. Do not defeat the purpose of the grounding-type plug.
Lamp
To avoid overheating and unacceptable image quality, replace the projection lamp with a lamp of the specified type. Refer to page 33 for lamp
specifications and to page 26 for instructions on replacing the lamp.
Lamp Compartment
To avoid burns, do not open the lamp module door until the projector is
turned off and the lamp has cooled for at least 30 minutes. Follow the
instructions in this manual for lamp replacement carefully.
Hot Surfaces
Allow the projector to cool at least 30 minutes before replacing a lamp.
When you open the lamp housing, be very careful not to touch the hot
surfaces inside.
NO TE: If you open the projector
case, you will void the warranty.
iv
Ventilation and Overheating
Openings in the projector case provide ventilation to protect it from
overheating. Keep loose papers and other objects well away from the
grills. Do not place the project or on top of or close to a computer or othe r
heat-producing eq uipment.
Liquid Spills
Do not set drinks on top of the projector. Spilled liquids can flow inside
and cause damage.
Do Not Disassemble
All service must be performed by an authorized In Focus service center.
The only user-serviceable part in the projector is the projection lamp,
which you can replace by opening the lamp cover on the bottom of the
projector (see page 26). Do not open any other part of the projector. If
your projector needs repair, ca ll your local Authorized Service Provider
or In Focus Technical Support as described on page 4. Before you call,
refer to “Troubleshooting” starting on page 29 to see if you can resolve
the problem yourself.
