Using this Shure ULXS14 wireless system is easy. First, connect the power supply to the receiver and turn it on. Then, turn on the bodypack transmitter. The system will automatically pair. When using the bodypack, make sure it's placed securely on your body. As for the antenna, position it in a place where it has a clear line - of - sight to the bodypack for the best signal. Before you use it, always check your country's wireless frequency laws. This is really important because using an illegal frequency can get you in trouble. To keep your system in good shape, clean the receiver and bodypack regularly with a soft, dry cloth. Avoid exposing it to extreme temperatures and moisture. Also, if you're not using the system for a long time, store it in a cool, dry place.
