  If you're experiencing noise, crackling, or unwanted signals, the issue might be related to antenna placement. Try relocating the receiver. Also, interference from other wireless systems, such as TVs, radios, CB radios, or defective electrical appliances, could be the cause. In this case, switch off the interference sources or defective appliances, or use a WMS 40 SINGLE/DUAL tuned to a different frequency. It's also advisable to have your electrical installation checked.

  If you are experiencing distortion with your AKG Microphone system, especially with a bodypack transmitter, the GAIN control might be set too high or too low. Adjust the GAIN control until the distortion stops. Also, interference from other wireless systems, such as TVs, radios, CB radios, or defective electrical appliances, could be the cause. In this case, switch off the interference sources or defective appliances, or use a WMS 40 SINGLE/DUAL tuned to a different frequency; have electrical installation checked.
