• Sound is Intermittent or Volume Goes Up and Down on CP810 / CP900

    • Use monitor earphones to see if the incorrect sound can be replicated. If not, it is more likely a counselling/coil/coil cable issue. If yes, it is more likely a processor issue.
    • Change program and observe changes.
    • Determine if telecoil or Auto telecoil is turned on by looking for a black /transparent green square on the Remote Assistant.
    • Change microphone protectors if not changed recently.
    • Try backups for suspected components one at a time and exchange the necessary suspected components.
  • Request for assistance
