Before replacing the lamp, check the serial number of the replacement lamp bulb (sold separately: 78-6969-9463-7 for MP7640i / 78-6969-9565-9 for MP7740i), then contact your local dealer. Before replacing the lamp, turn off the power, and unplug the power cord, then wait at least

45 minutes, in order to ensure that the lamp is properly cooled. Removing the lamp bulb while it is still hot could cause burns, or cause the lamp bulb to burst.

The LCD projector uses a glass lamp bulb. It is a mercury lamp with high WARNING internal pressure. High-pressure mercury lamps can break with a loud

bang, or burn out, if jolted or scratched, or through wear over time. 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.

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

If the replace lamp indicator (see "Related Messages" ( 34 ) and "Regarding the indicator Lamps" ( 35 )) comes on, 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 first time it is used, it is possible that there are electrical problems elsewhere besides the lamp. If this happens, contact your local dealer.

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.

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 projector’s internals, or cause injury during handling, so please do not try to clean the projector or replace the lamp yourself.

Obey local ordinances when disposing of used lamps. In most cases, it is possible to dispose of used bulbs in the same manner as used glass bottles, but in some cases, bulbs are sorted separately.

Do not use the projector with the lamp cover removed.
