CS70/CS70N Troubleshooting: Distortion/Echo in Handset

Article ID:



The sound in the handset is distorted/I hear an echo in the handset. What can I do?


To reduce or eliminate distortion/echo, try the following:
  • Reduce the speaking volume by changing the speaking volume major adjust switch setting.
  • Point the microphone towards your chin.
  • The listening volume is too high on the phone.  If you phone has a handset volume control, lower until the distortion disappears.
  • If the distortion is still present, lower the listening volume adjust button on the headset.  If the distortion persists, select another listening volume major adjust switch setting.
  • The base is too close to the computer or phone.
  • The system needs to be reset.  Perform a system reset as shown here.
