WARNING
● 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 life-
time, 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 in trash. Dispose of in
accord with environmental laws.
For lamp recycling, go to www.lamprecycle.org. (in the US) For product disposal, contact your local gov-
ernment agency or www.eiae.org (in the US) or www.epsc.ca (in Canada).
• If the lamp should break (it will make a loud bang when it does), unplug the power cord from
the outlet. Note that shards of glass could damage the projector's internals, or cause injury
during handling.
• If the lamp should break (it will make a loud bang when it does), ventilate the room well, and

• Before replacing the lamp, turn the projector off and unplug the power cord, then wait at least

45 minutes for the lamp to cool suffi ciently. Handling the lamp while hot can cause burns, as
outlet
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 above. This is dangerous,
since if the lamp's bulb has broken, the shards will fall out when the cover is opened. In addi-
tion, working in high places is dangerous.
• Do not use the projector with the lamp cover removed. At the lamp replacing, make sure that
the screws are screwed in fi rmly. Loose screws could result in damage or injury.
• Use only the lamp of the specifi ed type.
• If the lamp breaks soon after the fi rst time it is used, it is possible that there are electrical
problems elsewhere besides the lamp.
• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.
• If the indicators or a message prompts you to replace the lamp (see the section "Related
Messages" and "Regarding the indicator Lamps"), replace the lamp as soon as possible.
Using the lamp for long periods of time, or past the replacement date, could cause it to burst.
Do not use old (used) lamps; this is a cause of breakage.
