Replacing the Lamp

Projector lamps have a finite life. Replace the lamp when:

• A warning message “Lamp is approaching the end of its useful life in full power operation.

Replacement suggested!” appears on the screen.

• The image becomes darker and hues become weaker after a lamp has been for a long period

of time.

• The projector lamp LED indicator turns into amber. Refer to section titled “LED Indicator Mes-

sages” for further details.

« NOTE »

• The lamp will remain in high temperature even after the projector’s power is turned off. Wait

for at least 45 minutes after power off to cool down the lamp. Touching the lamp prior proper

cool down time can cause skin scalding.

• Do not touch any glass portion of the lamp at any time. The lamp may explode due to

improper handling or grease generated from finger.

• Lamp lifetime may differ from lamp to lamp and according to the environment of use. There

is no guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their

lifetime in a shorter period of time than other similar lamps.

• A lamp may explode as a result of vibration, shock or degradation as a result of hours of use

as its lifetime draws to an end. Risk of explosion may differ according to the environment or

conditions in which the projector and lamp are being used.

• Wear protective gloves and eyeglasses when fixing or detaching the lamp.

• Short on-off-cycles will damage the lamp and reduce lamp life. Wait at least for 7 minutes to

turn off the projector after powering on.

• Do not operate the lamp in proximity to paper, cloth, or other combustible material nor cover it

with such materials. Otherwise it could cause a fire.

• Do not operate the lamp in an atmosphere containing an inflammable substance, such as

thinner. Otherwise it could cause a fire or explosion.

• Thoroughly ventilate the area or the room when operating the lamp in an oxygen atmosphere (in

the air). If ozone is inhaled, it could cause headaches, nausea, dizziness, etc.

• The lamp contains inorganic mercury. If the lamp bursts, the mercury inside the lamp will go

out of the projector. Leave the area immediately if the lamp shatters while being operated and

ventilate the area for at least 30 minutes in order to avoid the inhalation of mercury fumes.

Otherwise it could be harmful to user’s health.

To replace the lamp:

1. Loosen the two screws of lamp cover.

2. Remove the lamp cover.

3. Loosen the two screws of lamp module.

4. Pull out the old lamp module by lamp handle.

5. Mount the new lamp.

6. Replace the lamp cover.

7. Reset the lamp timer.

« NOTE »

• Dispose of the used lamp according to local regulations.

• Ensure that screws are tightened properly. Screws not tightened fully may result in injury or

accidents.

• Since the lamp is made of glass, do not drop the unit and do not scratch the glass.

• Do not reuse the old lamp. This could cause the lamp to explode.

• Be sure to turn off the projector and unplug the AC power cord before replacing the lamp.

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