Replacing the lamp

A lamp has nite product life. Using the lamp for long periods of time could cause

the pictures darker or the color tone poor. Note that each lamp has a different

lifetime, and some may burst or burn out soon after you start using them.

Preparation of a new lamp and early replacement are recommended. To prepare

a new lamp, contact to your dealer and tell the lamp type number.

Type number : 456-8755H

1. Turn the projector off, and unplug the power cord.

Allow the projector to cool for at least 45 minutes.

2. Prepare a new lamp. If the projector is mounted

on a ceiling, or if the lamp has broken, also ask

the dealer to replace the lamp.

In case of replacement by yourself, follow the following

procedure.

3. Loosen the screw (marked by arrow) of the lamp

cover and then slide the lamp cover to the side to

remove it.

4. Loosen the 2 screws (marked by arrow) of the

lamp, and slowly pick up the lamp by the handles.

5. Insert the new lamp, and retighten rmly the

2 screws of the lamp that are loosened in the

previous process to lock it in place.

6. Slide the lamp cover back in place and rmly

fasten the screw of the lamp cover.

7. Turn the projector on and reset the lamp time

using the LAMP TIME item in the OPTION menu.

(1) Press the MENU button to display a menu.

(2) Point at the Go to Advanced Menu … in the menu

using the ▼/▲ button, then press the ► button.

(3) Point at the OPTION in the left column of the menu

using the ▼/▲button, then press the ► button.

(4) Point at the LAMP TIME using the ▼/▲ button, then

press the ► button. A dialog will appear.

(5) Press the ▲ button to select RESET on the dialog. It performs resetting the

Lamp cover

Handles

HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE

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 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 y 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

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, contact to 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 projector’s internals, or cause injury during handling,

so please do not try to clean the projector or replace the lamp yourself.

• 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.

• Before replacing the lamp, turn the projector off and unplug the power

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

a 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.

• Do not use the projector with the lamp cover removed. At the lamp

replacing, make sure that the screws are screwed in firmly. Loose

screws could result in damage or injury.

• Use only the lamp of the specied type.

• 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 to 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.
