Error Codes Error Message Description Recommended Solution
201 Bad Master The Copy process failed due to a read error which occurred on the Source device. Check the Source device by running the “Verify Source” function. If the device does not pass the “Verify Source” check, try duplicating using a different Source device.
202 No Device Found The duplicator does not detect any Target devices connected. Remove and then reconnect the Target devices. Make sure that the Green LED indicator is lit next to each Target device before starting the duplication process.

206 Targets & Master Size Mismatch! The Target devices are smaller in capacity than the Source device. Target devices have to be equal or greater in capacity than the Source. If the capacity on the Source and Targets are listed as being identical, please enable the “Size Tolerance” option in the Setup menu.
