PURPOSE:To realize a cost reduction as well as enhance the controllabrility, by displaying at least two displays among the displayes after switching by the common display element. CONSTITUTION:The power source is switched on, and the data of the channel selecting position, the sound volume, the low- and high-pitched sounds plus the balance each are read through nonvolatile memory 29 to be stored in random access memory RAM of microprocessor 25. And in the case of e.g. the display of the channel selecting position, the position data is delivered to display driving circuit 28 from RAM to light display element 12 of the channel selecting position mode. Then common display element 111 corresponding to the position is lit up. Thus common display elements 1111-1112 arranged in a row can be displayed by lighting up them from one to the other side and vice versa. As a result, the display driving circuit for each function can be excluded. |
