ŹThe 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 glassWRÀ\LQWRWKHODPSKRXVLQJDQGIRUgas containing mercury to escape from the projector’s vent holes.

ŹAbout 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), unplug the power cord from the outlet, and make sure to request a replacement lamp from your local dealer. Note that shards of glass could damage the inside of the projector, or cause injury during handling, so please do not try to clean the projector or replace the lamp yourself.

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.

• 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.
