When using the SMARTDAC+ GX/GP series' SNTP client function, if the power cuts out during recording start and I turn the power back on, the message, "E713 Incorrect SNTP server setting” or "E712 SNTP server does not respond" appears. What should I do?

Depending on the response speed such as hub or router connected to the main unit, it may take time before the Ethernet Link is established. Therefore, the error message will appear if the time adjustment by SNTP is performed before the Ethernet Link is established.
However, even if an error occurs, the time adjustment will be performed at the next synchronizing the time with the SNTP server. Therefore, you can just use the recorder continuously.
