PURPOSE:To improve both productivity and service properties, by executing a test mode based on a peculiar operation pattern. CONSTITUTION:Three types of operation patterns are set previously to an operation pattern detecting means 15, and each operation pattern is detected to deliver corresponding signals TEST1-TEST3. Test mode control means 16-18 deliver the control signal which controls each means to a control bus 2 to execute each test mode by the signals TEST1-TEST3. The 1st test mode control means 16 stores the digits corresponding to each selection key in the region of an RAM2A and checks the correspondence between the selection key and the RAM2A. The 2nd means 17 stores the data showing ''1''-''0'' and a character ''P'' in an RAM2B with correspondence to each digit. Then this data is displayed in an 8- shaped segment of a display device 19 for inspection of segments. The 3rd means 18 clears all data of the RAM2A. |
