Question

After turning on the power of the SA / SR-20 series, only the power LED lights up and it no longer runs.
The instruction word programmer is not installed and cannot be operated.
What should I do?

If the symptom does not change even if the power is turned on again, the operation cannot be performed unless the instruction word programmer (A-21P, R-21P) is attached.
Ask the equipment manufacturer, maintenance department, etc. to prepare a command word programmer.
