continuously)
2. When error occurs during check operation, check the error code and take appropriate measures.
- Refer to service manual if you need inspection or when other errors occur.
3. When check operation ends, use S-NET pro or S-CHECKER to issue a result report.
- Refer to service manual for further actions if you have any items with “inspection required” sign on the result report.
- After taking appropriate measure for the items with “inspection needed” sign, run the check operation again.
