CHAPTER 5. TEST FUNCTION
1. General4. Test contents
1) This diagnostic program has been developed for diagnosing ma-
chine functions in the field. The program is contained within the[1] Display & Buzzer test

Next, display the following segments (for approx. 1 sec.).
The key assignment must be properly set and the ROM and RAM
must be operating properly to go into this mode. This is necessary
