When power failure occurs
…
When power is supplied after a power failure, the device automatically starts operation again with
the same state as just before the power failure. It is danger that the device starts unattached
operation after a power failure.
We recommend for you to turn off the switch of device if a power failure occurs during operation.
In the case if the error other than listed above occurred, turn off the power switch and primary
power source immediately. Contact the shop of your purchase or nearest Yamato Scientific
Service Office.
