Method of simplifying the tuning of a radio telephone

Claim 1

A logic controlled method of tuning signals in a radio telephone having a logic section which controls its operation, characterized in that an external tuning equipment (2) is connected to the radio telephone's (1) signal interfaces (A, M) and auxiliary equipment interface (3) or corresponding interfaces, a test signal is connected to the radio telephone with the tuning equipment, the signal (S1, S2) to be tuned is selected via the radio telephone logic section (10), the auxiliary equipment interface (3) and the multiplexer (13), controlled by the tuning equipment (2), data proportional to the signal (S1, S2) to be tuned is directed through the A/D-converter (12), the logic section (10) and the auxiliary equipment interface (3) to the tuning equipment, the signal (S1, S2) to be tuned is compared with the target value in the tuning equipment (2), and in accordance with the comparison result the set value of the logic controlled amplifier (11, 11') is adjusted in a feed-back loop, until the desired tuning result for the signal (S1, S2) is obtained, the individual tuning results for the radio telephone (1) are stored in the non-volatile memory of the logic section (10), whereby the respective signal (S1, S2) is controlled with the stored set values during operation of the radio telephone.
