ABSTRACT:
Apparatus (100) for controlling the volume of a speaker (109) by restricting the volume level of the speaker (109) at power on. The apparatus (100) includes a microprocessor controller (103) for operating the speaker (109) at a first volume level prior to powering off. Upon power on, the microprocessor controller (103) determines a statistic based on a time of the received power-on command, and restricts the volume level of the speaker (109) based on the statistic.
