The Lamp - Hitachi PJ-TX10 Service Manual

6-8 The Lamp

WARNING
The projector uses a high-pressure mercury
glass lamp made of glass. 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.
• If the lamp should break (it will make a loud bang when it does), unplug the power cord from the outlet, and
make sure the type of the replacement lamp. Note that shards of glass could damage the projector's inter-
nals, or cause injury during handling.
• If the lamp should break (it will make a loud bang when it does), ventilate the room well, and make sure not
to breathe the gas that comes out of the projector vents, or get it in your eyes or mouth.
• Opening the lamp cover while the projector is suspended from above 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 danger-
ous, even if the bulb is not broken. Please be careful.
• 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.
• If the lamp breaks soon after the fi rst time it is used, it is possible that there are electrical problems else-
where besides the lamp.
• Use the lamp of the specifi ed type only. Type number: DT00611
• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.
• Before replacing the lamp, make sure the power switch is off and the power cable is not plugged in, then
wait at least 45 minutes for the lamp to cool suffi ciently. Handling the lamp while hot can cause burns, as
well as damaging the lamp.
• 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.
• The lamp in this product contains mercury. Dispose of the used lamp properly in accordance with applicable
environmental laws. In most cases, it is possible to dispose of used bulbs in the same manner as used glass bot-
tles, but in some cases, bulbs are sorted separately. In the US or Canada, especially, for Recycling and Disposal
information, contact your respective governmental Agencies or the Electronic Industries Alliance at
www.lamprecycle.org (in the US) or the Electronic Product Stewardship CANADA at www.epsc.ca (in CANADA).
