1. A method of tuning an alert device in a portable communication apparatus including 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.

10. 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; andthe 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
