MAINTENANCE
The projector is equipped with a three wire plug having a third (grounding) prong. This is a safe-
ty feature. If you are unable to insert the plug into the outlet, contact an electrician to have the
outlet replaced. Do not defeat the safety purpose of the grounding-type plug.
Ventilation
Before unplugging the power cord, make sure the internal lamp cooling fans have shut off. The
fans automatically shut off when the projector has adequately cooled down.
Slots and openings in the projector provide ventilation. To ensure reliable operation of the pro-
jector and to prevent overheating, these openings must never be blocked or covered. The projec-
tor should never be placed near or over a radiator or heat register. The projector should not be
placed in an enclosure unless proper ventilation is provided.
Do not push objects of any kind into the projector through the ventilation openings. They may
touch dangerous voltages or short-out components resulting in a fire or shock hazard. Do not spill
liquids of any kind into the projector. Should an accidental spill occur, immediately unplug the
projector and have it serviced by a qualified Runco service technician.
Servicing
If any of the following conditions exist, unplug the projector from the power outlet and refer serv-
ice to qualified Runco service personnel.
The power cord has been damaged.
The internal cooling fans do not come on when the projector is first turned on.
Liquid has been spilled into the projector.
The projector has been exposed to excessive moisture.
The projector does not operate normally.
The projector has been dropped or the case has been damaged.
Do not attempt to service the projector yourself. All servicing must be performed by a qualified
Runco service technician. If replacement parts are required, it is important that only Runco-
approved parts are used. Other parts may result in fire, electric shock or risk of personal injury.
4.2 Cleaning
Clean the projector when required. Before cleaning, always unplug the projector from the power
outlet.
Lens
To avoid the risk of scratching the lens, clean the lens only if absolutely required. A small amount
of dust on the lens will have very little effect on picture quality. If the lens must be cleaned, use
a DRY soft cotton cloth. Clean gently in a circular motion.
Lamp
It is important to never touch the glass surface of the lamp, as the oil imprint will seriously
degrade lamp performance. Should you accidentally touch the surface of the lamp, clean careful-
ly with a lint-free cloth moistened with isopropyl alcohol.
