ABSTRACT:
In a method and apparatus according to the invention the tuning information determined by a measuring computer (20) is stored in the memory of the radio telephone (1). When the radio telephone is in operation the microprocessor (10) receives from the sensors (14) information e.g. about the temperature, and it selects from its memory tuning information, with which the transmitter (11) power is controlled via a D/A-converter (15). The tuning can be made automatically, without opening the casing of the radio telephone.
