Using the ADJ Wiflex DMX System is easy. First, make sure the power supply included in the package is properly connected to both the transmitter and the receiver. Then, set up the transmitter near the source of the DMX signals and the receiver at the destination within 500 feet. Once they're powered on, they'll start transmitting and receiving signals automatically. When using, keep the transmitter and receiver away from strong electromagnetic fields as it may interfere with the signal. Also, avoid exposing them to extreme temperatures and humidity. For maintenance, simply use a dry cloth to wipe the exterior of the devices regularly. This will help keep them in good working condition.
