This Sennheiser wireless system operates at 626 - 662 MHz and is for use outside the U.S. Before buying, check your country's wireless frequency regulations as some frequency ranges may be illegal in certain countries. It includes a receiver, transmitter, and antenna(s), but no power supply. The belt pack antenna has some missing plastic shielding but still works well.

How to use: First, make sure you've checked your country's wireless frequency laws. Then, connect the receiver and transmitter properly. Place the antenna in a good position for better signal reception. Note that this system doesn't come with a power supply, so you'll need to provide your own. Maintenance: Keep the system clean and dry. If the antenna gets damaged further, it might affect the signal. Store it in a safe place when not in use.
