WARNING: To avoid electric shock, turn off the unit and unplug it while connecting devices to the DX4000. Adequate ventilation is required for proper operation of the DX4000. Allow two inches of space above the unit and on each side for air circulation.
1.Connect up to four cameras at the video inputs. Refer to Table A for video coaxial cable distances. The DX4000 features automatic termination of video if no loop out cables are attached. Remove all unused cables from the video output ports.
2.If desired, connect analog monitors to the video outputs (looping). Refer to Table A for video coaxial cable distances. You must terminate all monitors. If you connect a single monitor to an output, terminate the monitor at 75 ohms. If you connect more than one monitor to an output, terminate the farthest monitor at 75 ohms, and terminate the others at
3.If desired, connect an analog monitor to the main monitor output. Refer to Table A for video coaxial cable distances. If you connect more than one monitor to an output, terminate the farthest monitor at 75 ohms, and terminate the others at
4.If desired, connect a spot monitor to the DX4000. Refer to Table A for video coaxial cable distances. If you connect more than one monitor to an output, terminate the farthest monitor at 75 ohms, and terminate the others at

5. Select the video stream type for the cameras. Choices are NTSC or PAL.
WARNING: Changing the video stream type from NTSC to PAL reformats the hard disk. Do not change video stream types until any recorded video has been backed up to CD or a removable USB flash memory device.
