Then, turn on the BLX88 wireless receiver and the BLX2/SM58 handheld microphone transmitter. Adjust the settings on the receiver to match the transmitter. You're now ready to start playing or singing! When it comes to maintenance, keep the system in a dry and clean place. Wipe it down with a soft cloth regularly. Remember to check your country's wireless frequency laws before using it. Using an illegal frequency range can get you in trouble. And don't forget to use the correct power supply that comes with the package to avoid any damage to the equipment.
