HIGH TEMPERATURE

HIGH PRESSURE

 

►The projector uses a high-pressure mercury glass lamp. The lamp can break with a loud bang, or burn out, if jolted or scratched, handled while hot, or worn over time. Note that each lamp has a different lifetime, and some may burst or burn out soon after you start using them. In addition, when the bulb bursts, it is possible for shards of glass to fly into the lamp housing, and for gas containing mercury to escape from the projector’s vent holes.

►About disposal of a lamp • This product contains a mercury lamp; do not put it in a trash. Dispose of it in accordance with environmental laws.

For lamp recycling, go to www.lamprecycle.org. (in the US)

For product disposal, contact your local government agency or www.eiae.org (in the US) or www.epsc.ca (in Canada).

For more information, call your dealer.

 

• If the lamp should break (it will make a loud bang when it does),

comes out of the projector vents, or get it in your eyes or mouth.

 

• Before replacing the lamp, turn the projector off and unplug the power

 

cord, then wait at least 45 minutes for the lamp to cool sufficiently.

 

Handling the lamp while hot can cause burns, as well as damaging the

 

lamp.

 

• Never unscrew except the appointed (marked by an arrow) screws.

 

• Do not open the lamp cover while the projector is suspended from

 

the ceiling. This is dangerous, since if the lamp’s bulb has broken, the

 

shards will fall out when the cover is opened. In addition, working in

 

high places is dangerous, so ask your local dealer to have the lamp

 

replaced even if the bulb is not broken.

 

• Do not use the projector with the lamp cover removed. To replace the

 

lamp, make sure that the screws are tightened firmly. Loose screws

 

could result in damage or injury.

 

• Use only the lamp of the specified type.

 

• If the lamp breaks soon after the first time it is used, it is possible

 

that there are electrical problems elsewhere besides the lamp. If this

 

happens, contact your local dealer or a service representative.

 

• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.

 

• Using the lamp for long periods of time, could cause it dark, not to

 

light up or to burst. When the pictures appear dark, or when the color

 

tone is poor, please replace the lamp as soon as possible. Do not use

 

old (used) lamps; this is a cause of breakage.
