CS70/CS70N Troubleshooting: Buzzing in Background

Question

My callers report hearing a buzz in the background of the calls. What can I do?

Answer

If your callers report a buzzing in the background, try:

  1. Muting your headset. If the buzz stops, the microphone is defective. You should replace your voice tube (CS70) or the headset (CS70N).
  2. Placing your hand within half an inch of your microphone. If the buzz becomes louder, the microphone is defective. You should replace your voice tube (CS70) or the headset (CS70N).
  3. Plugging your base power supply directly into the wall if you currently have it plugged into a power strip.
  4. Moving the base around on your desk. If the buzz changes as you move it around, it is possible that something is causing interference. Try to determine the source of interference. You may want to try turning off the electronics on your desk. If the buzz disappears when you turn off a device, try plugging that device or the headset power supply into a different outlet.
  5. You may be picking up another radio frequency.  Contact our Technical Assistance Center for an RF filter.
