14. A hearing assistive system comprising a hearing assistive device and a remote-control unit for controlling the hearing assistive device by sending a control signal with instructions as an acoustic signal, the remote-control unit having a processor, an input transducer, an output transducer, and a memory, the processor is adapted for controlling a calibration process during which:
the remote-control unit is adapted for outputting tones applied by the control signal via the output transducer,
the hearing assistive device is adapted for receiving the tones and evaluating tone level of the received tones,
the processor is adapted for:
adjusting relative volumes of the tones applied by the control signal in dependence of the evaluation, and
storing the adjusted relative volumes of the tones for use when sending a control signal with instructions as acoustic signals.
