Using this Shure ULXS14 wireless belt pack system is easy. First, connect the antenna to the bodypack properly. Then, pair it with your compatible device following the device's pairing instructions. Note that this system doesn't come with a power supply, so you'll need to get one separately. Before using it, check your country's wireless frequency laws to avoid any legal issues. For maintenance, keep the bodypack and antenna clean. Wipe them gently with a soft, dry cloth. Store the system in a cool, dry place when not in use to extend its lifespan.
