Replacing the Lamp

As the projector operates over time, the brightness of the projector lamp gradually decreases
and the lamp becomes more susceptible to breakage. We recommend replacing the lamp if a
warning message is displayed. Do not attempt to replace the lamp yourself. Contact the qualified 
service personnel for replacement.
Replace the lamp when:

„

A warning message “The lamp is approaching the end of its useful life. Replacement
suggested!" appears on the screen.

„

The projector lamp LED indicator turns into red. 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 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.
