PURPOSE:To discriminate at what number-th operation in setting time a current operation is by providing an incoming call display means comprising light emitting diodes different from a lighting color each connecting to an incoming call display drive circuit respectively. CONSTITUTION:A CPU 1 is provided with 1st and 2nd output ports 1a, 1b corresponding to two pieces of setting time, and a 2-color light emitting diode 4 comprising 1st and 2nd light emitting diodes 4a, 4b is adopted for an incoming color display means. When an incoming call comes to a radio equipment 100 of a portable telephone set during a 1st operation setting time, a signal is outputted to the 1st output port 1a of the CPU 1 to activate a color drive circuit 2. Thus, a red light emitting element diode 4a of the 2-color light emitting diode 4 is lighted. Furthermore, when an incoming call comes to the radio equipment 100 of the portable telephone set during a 2nd operation setting time, a signal is outputted to the 2nd output port 1b of the CPU 1 to activate the color drive circuit 2. Thus, a green light emitting element diode 4b of the 2-color light emitting diode 4 is lighted. |
