It is constructed so that combinations of display colors or lighting patterns can be set from the outside by incoming notification means by light of a portable telephone apparatus. That is, incoming notification pattern data by a change in lighting colors and data of the tempo are stored in RAM 3, and data from the RAM 3 is held in an FIFO 8 and is outputted every tempo according to a read signal from an FIFO read signal generator 9, and also by generating an interruption at the time when a predetermined amount of data is outputted, a CPU 1 writes subsequent data from the RAM 3 to the FIFO 8 according to the interruption. Then, data read from the FIFO 8 is once held in an output port register 5 and an LED driver 6 independently drives plural LEDs according to data outputted from the output port register 5. In this case, it is constructed so that the data from the RAM 3 can be set from the outside.
