Remote Control Instructions  
•
•
•
Reflection may be affected by the environment under some circumstances. Aim the remote control at the project to try again if  
it happens.  
* Change the battery if the effective distance of the remote control is reduced or the remote control does not work.  
When the terminal of the remote control cable is inserted to the wired control terminal of the projector, the projector will  
automatically switch to the wired control mode and cannot be controlled through the IR signal of the remote control. Disconnect  
the wired control terminal on the projector if you want to control through the IR signal of the remote control.  
Pay attention to the installation environment because the signal may not work due to interference if the IR remote sensor is  
exposed to the bright sunlight or fluorescence.

There are 6 fixture screw holes at the bottom of projector for ceiling mounting, the available  
installation options as below�  
Front: Install the projector on the table and project the image forward�  
Rear: Install the projector on the table and project the image from rear�  
Ceiling + Front: Mounting the projector on the ceiling and project the image forward�  
Ceiling + Rear: Mounting the projector on the ceiling and project the image from rear�  
Up + Front: Projector is mounted vertically upwards and project image upwards�  
Down + Front: Projector is mounted vertically downwards and project image downwards�

Cautions on ventilation  
The product is a high-brightness projector. The intake with filters are located on the front and  
right sides to provide sufficient air for cooling. The projector has two vents on the back for  
cool air discharging� Make sure the intake and vent are unobstructed when the projector is  
being installed� At least 50cm around the intake and 70cm around the vent should be clear�

Note:  
• If the installation distance is not enough, the projector may enter the system protection mode due to the  
rising ambient temperature after running for a while. Then, projection may be interrupted.  
• The service life of components or lamps may be reduced due to the long-term effect of the ambient  
temperature if the installation distance is not appropriate.  
• If the projector has to be installed in a box or a closed environment due to the installation requirements,  
the external intake and vent system should be designed additionally to ensure that there is enough air for  
cooling or the projector will not be surrounded by heat.

through the standard 9-pin serial cable (Straight Through Serial Cable)� Refer to the  
remote control guidelines for detailed 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 input port to  
expand the working range of the remote control�  
• 3D Sync Out: 3D IR sync signal transmitter�  
Note:  
• When the terminal of the remote control cable is inserted to the wired control terminal of the projector, the  
projector will automatically switch to the wired control mode and cannot be controlled through the IR signal  
of the remote control. Disconnect the wired control terminal on the projector if you want to control through  
the IR signal of the remote control.  
• 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  
before insertion.

Connecting to the External HDBaseT Transmitter  
The projector has a built-in HDBaseT signal receiver� With the HDBaseT Transmitter  
(optional), the video, RS-232 and LAN signals can be sent to the projector via a single  
RJ-45 cable� If the HDBaseT Transmitter you purchased supports the input and output of  
the IR remote control, the control signals from the IR remote control can be sent to the  
DU6871/DW6851/DX6831 projector via the RJ-45 cable�

Note:  
• The projector supports the video signal, R-232, IR remote control and the reception of the network control  
signals but do not support Power over Ethernet (PoE).  
• Set the Control->RS232->Channel on the OSD menu to HDBaseT if you want to use the external  
HDBaseT transmitter to send the RS232 command to the projector via the RJ45 cable and baud rate will  
switch to 9600.  
• If the command is sent via the HDBaseT transmitter, the longest transmission distance is 100 meters. The  
projection may be interrupted or interfered, or the control signal cannot be sent if the transmission distance  
is exceeded.  
• Use the RJ-45 Cat5e or above cable and avoid entwining. Entwining may cause damage, interfere signal  
transmission, reduce the transmission distance and degrade the image quality.

abnormal. The corresponding LED indicator of the lamp will flash simultaneously for seconds and light up.  
2. When the lamp mode is set to Single, the setting will become valid upon turn-on of the projector next time.  
3. Quick switch of the lamp mode may affect the life of the lamp. The projector will disable the lamp mode

ECO: Projection is carried out in the energy saving mode to ensure the longest service  
life of the lamp�  
Custom Power Level: In addition to the Normal and ECO modes, the lamp power  
equal to 100% to 75% of the power in the Normal mode is used for fine-tune of the  
brightness in the Custom Power Level mode� This function can be used for quick

• High Altitude  
Use this function to control the cooling fan of the projector� You can set it to OFF or ON,  
the default setting is OFF�  
Normally, the projector can operate normally when this function is set to OFF� The  
projector detects ambient temperature by default to regulate the cooling fan speed�  
When the temperature rises, the cooling fan speeds up (with higher noise) to exhaust  
the internal heat energy out of the projector and ensure its normal operation� However,  
the projector may turn off automatically if it is used in an environment at excessively  
high temperature or in an area at a high altitude� In this case, you can enable this  
function by setting it to ON and have the cooling fan operate at a higher speed to  
control the internal temperature of the projector�  
Note:  
• The area at a high altitude means the place at an altitude of more than 5000 feet.  
• Custom Power Level  
Use the ◄► function to select the Custom Power Level. The projector allows a custom  
power level equal to 100%~75% of the lamp power in the Normal mode� This function  
is available only when the lamp power is set to Custom Power Level� It cannot be  
selected (highlighted) in the Normal or ECO mode�
