Replacing the Lamp

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

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 red. Refer to section titled “Indicator Messages” for further details.

NOTE

The lamp becomes high temperature after turning off the projector with the power button. If you touch the lamp, you may scald your ﬁnger. When you replace the lamp, wait for at least 45 minutes for the lamp to cool down.

Do not touch the lamp glass at any time. The lamp may explode due to improper handling, including the touching of the lamp glass.

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. Faster on-off-cycles will damage the lamp and reduce lamp life. Wait at least for 5 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 inorganic mercury is involved in the lamp. 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.
