SAL number?
The SATA Authentification Label is used to identify a SATA product as an original product, beyond a doubt, via the SAL check. With the SATAjet X 5500 universe, the 10-digit SAL number can do even more than that: it grants you access to the SATA universe. You can find the 10-digit number directly on your spray gun. The SAL number can be found also on the hologram security label of the packaging, directly above the barcode.
