Using this Shure P7R-L2 wireless bodypack receiver is simple. Just connect it to your compatible device as per the instructions. But here's what you need to know. First, always check your country's wireless frequency laws before using it, because some frequency ranges may be illegal. Also, don't use it in the U.S. as it's not allowed there. For maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If it gets dirty, use a soft, dry cloth to gently wipe it. That way, you can enjoy using your receiver for a long time.
