(3) Control voltage check terminal of CTL circuit board
Appearance of CTL circuit board assembled inside the front panel of SC-500 is as below.
Control voltage check terminals are set up and the check whether or not the respective voltages are abnormal
can be performed.
[DANGER] There is a danger of electric shock since the work is performed with the power ON.
Do not perform the work by any person other than technicians who have electrical
