Using this Shure ULXS24/58 handheld wireless system is easy. First, make sure to get a suitable power supply and batteries as they aren't included. After setting up the ULXS4 receiver and ULX2 handheld transmitter, you're ready to start using it. Before using, double - check your country's wireless frequency laws to avoid any legal issues. When it comes to maintenance, keep the system in a dry and clean place. Since the grille is dented, be extra careful not to damage it further. If you have any problems, contact Shure's customer service for help.
