1. An apparatus to adjust the transmission power of a portable radio transmitter comprising:
- a proximity detector configured to detect the proximity of a person to the portable radio transmitter; and
a power setting unit responsive to the proximity detector and configured to one of lower transmission power of the portable radio transmitter by a first predetermined step when the person is in proximity of the portable radio transmitter or increase the transmission power of the portable radio transmitter by a second predetermined step when the person is not in the proximity of the portable radio transmitter;
wherein the power setting unit is configured to set an amount of the first and second predetermined steps such that the transmission power of the portable radio transmitter belongs to a same power class that the portable radio transmitter belonged prior to lowering or increasing the transmission power.

Abstract
Methods and apparatus for adjusting the transmission power of a portable radio transmitter are disclosed. The apparatus includes a power setting unit responsive to a proximity detector that lowers the transmission power of the portable radio transmitter when a person is in proximity to the transmitter and increases transmission power when a person is not in proximity to the transmitter. The power setting unit determines the amount of power increase or decrease in such a way that the transmission power of the transmitter is kept in a same power class as prior to the decreasing or increasing of the transmission power.
