HIGH VOLTAGE

HIGH TEMPERATURE

HIGH PRESSURE

To replace the lamp, check the model number of the replacement lamp (sold separately) and contact your local dealer.

Replacement lamp model number: 78-6969-9601-2

If the projector is mounted on the ceiling, or if the lamp has broken, ask your dealer to replace the lamp. Lamp replacement is hazardous and should not be attempted by the user.

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

WARNING

The LCD projector uses a glass lamp bulb. It is a mercury lamp with high 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.

• 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 addition, working in high places is dangerous, so ask your local dealer to have the lamp replaced even if the bulb is not broken.
• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.
• If the replace lamp indicator (see "Related Messages" (38) and "Regarding the indicator Lamps" (39)) 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 or a service representative.
• 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.

THE LAMP (continued)

Replacing the lamp

All projector lamps will wear out eventually. If used for long periods of time, the image could become darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps early. If the LAMP indicator turns red, or a message prompts you to replace the lamp when you power up the projector, the lamp needs to be replaced. (See "Related Messages" (38) and "Regarding the Indicator Lamps" (39) for details.)

1 Turn off the projector, and unplug the power cord. Allow the lamp bulb to cool for at least 45 minutes, and prepare a new lamp.

2 After making sure that the projector has cooled adequately, slide the knob of a lamp cover lock as shown in the figure. Then, one side of the lamp cover is raised. Pull up the lamp cover and remove it, as shown in the figure.

3 Unscrew the 3 screws, and slowly pull out the lamp by the handle.

- Be careful not to touch the inside of the lamp case.

4 Insert the new lamp, and tighten the 3 screws firmly to lock it in place.

5 Interlocking the 2 tabs of the lamp cover to the projector, put the lamp cover on the projector.

Then push the point of the lamp cover to fix it, as shown in the figure.

Make sure that the lamp cover doesn't come up.

6 Turn on the projector power, and reset the lamp timer.

- To reset the lamp timer, from the OPTION menu, select the LAMP TIME. (31)

ATTENTION • Make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.

• Do not use with lamp cover removed.
• Do not reset the lamp timer without replacing the lamp. Reset the lamp timer always when replacing the lamp. The message functions will not operate properly if the lamp timer is not reset correctly.
• When the lamp has been replaced after the message of “CHANGE THE LAMP .....THE POWER WILL TURN OFF AFTER 0 hr.” is displayed, or the LAMP indicator is red, complete the following operation within 10 minutes of switching power on.

NOTE • The LAMP indicator is also red when the lamp unit reaches high temperature.

Before replacing the lamp, switch power off, wait approximately 20 minutes, and switch power on again. If the LAMP indicator is still red, replace the lamp.

Caring for the air filter

The air filter should be cleaned about every 100 hours. If the LAMP indicator and TEMP indicator blink red simultaneously, or a message prompts you to clean the air filter when you turn on the unit, the filter needs to be cleaned. (See "Related Messages" (38) and "Regarding the Indicator Lamps" (39) for details.)
