Regarding the HOLD terminal of the MICROCOMPUTERWhen the HOLD terminal (INPUT) of the MICROCOMPUTER is “H”, the

21、 MICROCOMPUTER is judged to be operating correctly.When this terminal is “L”, the main power cannot be turned on.

24、cuit in the power supply block, electric potential is kept charged acrossthe electrolytic capacitors (C101, 102) even though AC power cord is removed. If repair is attempted in this condition, secondary defectcan occur.In order to prevent the secondary trouble, perform the following measures before

25、starting repair work.Discharge procedure11111Remove the AC power cord.22222Connect a discharging resistor at an end of lead wire thathas clips at both ends.

Regarding resetThere are cases that the machine does not work correctly because the MICROCOMP

28、UTER is not reset even though the AC powercord is re-inserted, or the software reset (pressing the STOP key + POWER key) is performed.When the above described phenomenon occurs, it can lead to wrong judgement as if the MICROCOMPUTER is defective and toexchange the MICROCOMPUTER. In such a case, perf
