To use this Shure UR1M bodypack transmitter, first make sure your country allows the 470 - 530 MHz frequency range. You'll need to supply your own batteries as they're not included. After inserting the batteries, turn on the unit and connect it to your audio source. When not in use, store it in a cool, dry place. Avoid exposing it to extreme temperatures or moisture. As it's only power - tested, keep an eye on its performance during initial use. If you notice any issues, reach out to Shure's customer service.
