DU6675 DLP Projector - User's Manual  
Maintenance  
Replacing the lamp  
Depending on the lamp model, the lamp life is affected by the installation method and  
frequency of the lamp on/off operation. It is suggested to replace the projector lamp when  
the lamp is used for approximately 2500 hours to ensure high projection quality. In the  
OSD Menu, the lamp using time can be checked from the "OSD Menu - SERVICE". The  
lamp should be replaced when the projected image is obviously darkened. Contact your  
local dealer to purchase the authorized new lamp suitable for your projector.  
Note:  
• Purchase the lamp module produced by Vivitek. Using the lamp that is not made by Vivitek may affect the  
performance of the projector or damage the projector.  
Lamp Handling Precautions:  
• This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling  
may result in accidents, injury, or create a fire hazard.  
• Lamp life may differ from lamp to lamp and according to the environment of use. There is no guarantee-tee  
of the same life for each lamp. Some lamps may fail or terminate their life in a shorter period of time than  
other similar lamps.  
• If the projector indicates that the lamp should be replaced, i.e., if LAMP 1 and/or LAMP 2 light up, re-  
place the lamp with a new one IMMEDIATELY after the projector has cooled down. (Follow carefully the  
instructions in the Lamp Replacement section of this manual.) Continuous use of the lamp with LAMP 1  
and/or LAMP 2 lighted may increase the risk of lamp explosion.  
• 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.  
• If a lamp explodes, the following safety precautions should be taken:  
• Disconnect the projector’s AC plug from the AC outlet immediately. Contact an authorized service station  
for a checkup of the unit and replacement of the lamp. Additionally, check carefully to ensure that there  
are no broken shards or pieces of glass around the projector or coming out from the cooling air circulation  
holes. Any broken shards found should be cleaned up carefully. No one should check the inside of the  
projector except those who are authorized trained technicians and who are familiar with projector service.  
Inappropriate attempts to service the unit by anyone, especially those who are not appropriately trained to  
do so, may result in an accident or injury caused by pieces of broken glass.  
• The projection lamp should be replaced when it burns out. It should only be replaced with a certified  
replacement part, which you can order from your local dealer.  
Warning:  
• Be sure to turn off and unplug the projector at least 30 minutes before replacing the lamp. Failure to do so  
could result in a severe burn.  
• Safety glasses should be worn when replacing the lamp while the projector is ceiling mounted
