Abstract
A method of tuning an alert device in a portable communication apparatus having a microphone. The method involves the steps of recording, through the microphone, an acoustic signal which is emitted by the alert device in response to a drive signal; deriving a characteristic value of the recorded signal; comparing the characteristic value with a reference value and generating a comparison result; and controlling the drive signal of the alert device in response to the comparison result.

A method of tuning an alert device in a portable communication apparatus having a microphone, comprising the steps of:
- recording, through the microphone, an acoustic signal which is emitted by the alert device in response to a drive signal;
- deriving a characteristic value of the recorded signal;
- comparing the characteristic value with a reference value and generating a comparison result;
- and
- controlling the drive signal of the alert device in response to the comparison result.
A portable communication apparatus having a microphone, an alert device and a controller, wherein
- the microphone is adapted to record an acoustic signal, which is emitted by the alert device in response to a drive signal, and
- the controller is adapted to derive a characteristic value of the recorded signal, to compare the characteristic value with a reference value, to generate a comparison result and to control the drive signal of the alert device in response to the comparison result.
