Please quote ALL the LETTERS+NUMBERS on ANY BARCODES , LABELS or STAMPED IN THE METAL CASING.

There should be a 14 character Serial Number beginning with RG or RN or PH or similar (often found stamped in the metal casing ) and maybe a Security Number in the format of TOA123 or TA123 or just A123 at the end of a barcode so please quote EVERYTHING you can find

Hello there!

Classic scenario: removed the battery - code required - user doesn't have any idea

The details
Model: 22RC624
PROD NO: BS00 99 21 9055471
I can't find anything else, no code engraved on the sides (only this is engraved "TN M5X6 max"), only the model and prod number.

Hope its enough, many thanks in advance!
