16-3. List of error codes
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall
outlet before opening the face plate of the control box. Touching areas where high voltages are present can
result in severe injury.
Turn off the power switch and disconnect the power cord before carrying out troubleshooting, otherwise the
machine will operate if the treadle is pressed by mistake, which could result in injury.
If an error code appears in the LED display on the operation panel, check the error code and then turn off the power.
(However, the error display will not disappear immediately when the power is turned off.)
After the panel display turns off, remove the cause of the error and then turn the power back on. (Except for error
