ABSTRACT:
A radio tele-communication apparatus of this invention is arranged as follows. A receiving circuit receives a signal including transmission information transmitted from a base station and outputs a demodulated signal. A determining circuit determines whether or not self-addressed transmission information is included in the demodulated signal output from the receiving circuit. If the determining circuit determines that the self-addressed transmission information is included in the demodulated signal, a detecting circuit compares the currently received transmission information with previously received transmission information to detect a change amount therebetween. If the change amount is larger than a predetermined amount, an informing circuit informs reception of the self-addressed transmission information. The informing circuit also contains various informing states which can be adjustably set by the user.
