Connecting to the Video Device

Connect the video equipment to the input port of the projector via the DVI-D, HDMI, Component Video, Composite Video or S-Video Connector.

Connecting to the Control Equipment

The projector has the following control port for connecting to the control equipment:

• HDBaseT/LAN (Network control): The projector supports network control via LAN/HDBaseT terminal. LAN and HDBaseT share the port. If only network control is used, you can connect the LAN on the projector to PC or through the local network. Refer to the Remote Communication Guide for more detail information.
• RS-232 (RS-232 control): The projector can be controlled by RS-232 command via connecting the projector to PC or control system through the standard 9-pin serial cable. Refer to the Remote Communication Guide for detail information.
• Wired remote control: If the projector cannot receive the IR signal from the remote control due to the overly long distance or obstacles, you can connect the cable to the IR remote control or the external IR transmitter (optional) via the WIRE port to expand the working range of the remote control.
  • 3D Sync Out: Connect to 3D IR sync signal transmitter.

Note:

- If the wired remote control cable or the external IR transmitter is inserted to the incorrect port, such as Trigger, the remote control or the IR transmitter may be damaged. Make sure whether the port is correct.

Connecting to the Screen Trigger

If your projection system includes the Electric projection screen and other 12V trigger device, you can connect these devices to the Trigger and configure the settings on OSD. The projector will output 12V signal when turning on the projector.

Connecting to External HDBaseT Transmitter

The projector has a built-in HDBaseT receiver. With HDBaseT transmitter (optional), the video, RS-232 and LAN signals can be sent to the projector via a single RJ-45 cable. If HDBaseT you purchased supports to output the IR remote control, the control signals from the IR remote control can be sent to the DU6675 projector via the RJ-45 cable.

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, replace 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

Caution:

• Do not use abrasive cleaners or solvents.
  • To prevent discoloration or fading, avoid getting cleaner on the projector case.

Cleaning the Filters

The projector uses three filters to keep the fans free of dust and other particles, and should be cleaned every 500 hours of operation. In dusty environments, it is recommended to clean the filters more frequently. If the filter is dirty or clogged, your projector may overheat. When the message be-low is displayed, the filters must be cleaned.

Note:

- When the filter message is displayed, please clean all three filters at the same time to synchronize the Filter time display. The Filter Message item should be enabled in the Options menu.

Refer to the following guide to clean the filters.

1. The left and rear filters can be cleaned as demonstrated in the following images.
