※ Q&A ( Common questions asked by customers)

1) Q : What if duplicate tables are created during recording and playback ?

    A : 1. If the MAC address changes, the device is recognized as a different one and a duplicate

            table is created.

         2. If the GMT time has changed ( if the time goes back to the past during recording )

         3. If distributed storage is set

2) Q : How can I restore the existing settings without its backup file after replacing the motherboard?

    A : With CS-TOOL, you must first perform a factory reset of the motherboard to be replaced.
