Bell Noise

This apparatus does not incorporate circuitry to suppress bell-tinkle during dialing. It has been found that when used with some electronic ring type telephones and on two wire circuits that bell tinkle will occur during dialing. This is not a fault and we advise you not to call the Fault repair service.
