Abstract
In accordance with the invention a radio telephone (1) is tuned so that the tuning equipment (2) selects the signal (S1, S2) to be tuned via the microprocessor (10) and the multiplexer (13), and that the logic controlled amplifiers (11, 11') are controlled to obtain the desired tuning result. The set values corresponding to the tuning result are stored in the microprocessor memory. When the radio telephone is in operation, the signals are amplified in accordance to the set values. The tuning can be performed without opening the radio telephone.
