<p>PROBLEM TO BE SOLVED: To surely and easily set the data of radio by inputting key data including plural pieces of setting data to radio and writing them in a memory by means of an external expansion input device having a prescribed function. SOLUTION: A key data input terminal 21 and a clock input terminal 22 for synchronization of an external expansion input device 20 are connected to a key data inputting means 15 and a clock outputting means 16 respectively through the external terminals of radio 1, and power is fed. A transmission SW4 and a monitor SW5 set a data setting mode, plural pieces of setting data and frame synchronous data are produced by operating a prescribed setting switch of the device 20 and are outputted from the terminal 21 to the radio 1 in accordance with a synchronous clock. The radio 1 fetches them in a setting mode managing means 7 of a microcomputer 2 through the means 15, stores them in a RAM 8 and after that, writes setting data in an external storage device 14 by operating a write function key. When the writing is finished, the end is indicated in a LED 31.</p> |
