Replacing the Lamp

Projector lamps have a nite 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 amber. Refer to section titled “LED

Indicator Messages” for further details.

 The lamp becomes high temperature after turning off the projector with the power

button. If you touch the lamp, you may scald your nger. 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 xing 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 re.

 Do not operate the lamp in an atmosphere containing an inammable

substance, such as thinner. Otherwise it could cause a re 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.
