S10/S12: Humming Noise

Article ID : 000006678


Why do I hear a hum in the headset of the S10 or S12?


  • Adjust the compatibility slide switch until the sound is clear.
  • Try other switch settings (It will not harm the headset or your phone).
  • Try installing the headset on another phone in another location; if the hum is still present you may need to replace the unit.
