<p>The present invention relates to a procedure for using a radio phone (2) with an external amplifying means (1) for receiving, amplifying and transmitting a radio frequency reception signal to the radio phone, in which radio phone a reception frequency signal is supplied to a front end amplifier (9). When the external amplifying means (1) is connected to the radio phone, the front end amplifier (9) of the radio phone is bypassed or the gain thereof (9) is adjusted to be lower. The control signal (OHJ) is preferably a voltage control signal of direct voltage frequency or low frequency produced in the amplifying means (1), which in the amplifying means is added into the reception signal, and in the radio phone separated from the reception signal into a control signal of the front end amplifier. <IMAGE></p> |
