Using your Sennheiser SKM 500 G4 - AW+ is easy. First, make sure it's properly charged or has fresh batteries. Turn it on and pair it with your compatible receiver. When speaking or singing, hold the transmitter at a comfortable distance from your mouth for the best sound. Remember to check your country's wireless frequency laws before using it, as some frequency ranges may be illegal. To keep it in good shape, clean the microphone capsule gently with a soft, dry cloth. Store it in a cool, dry place when not in use. If you encounter any problems, refer to the user manual or contact Sennheiser support.
