Using the Behringer ULM300MIC Wireless Handheld Microphone System is a breeze. First, turn on the ULM300RS single - channel receiver and the ULM300M handheld microphone. You can adjust the volume using the volume up and down buttons on the microphone. When you need to quickly silence the sound, use the panic mute feature. The system has a maximum range of 200 feet or 60 meters, so you can move around freely within this area. For audio output, you can connect the receiver to your audio equipment using the balanced XLR or unbalanced 1/4' TS connectors. As for maintenance, keep the microphone and receiver clean. Avoid exposing them to extreme temperatures, moisture, or dust. If the system is not in use for a long time, turn it off and store it in a safe place. This way, you can enjoy high - quality sound from your Behringer microphone system for a long time.
