Using the Shure SLX14 Belt Pack Wireless System is easy. First, make sure you've checked your country's wireless frequency laws as it can't be used in the U.S. and some frequencies might be illegal elsewhere. The system includes a bodypack and a receiver. Since it doesn't come with a power supply or antennas, you'll need to get those separately. When using it, place the bodypack in a suitable position on your body. As for maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures and moisture. Store it in a safe place when not in use.
