This page describes the bits available in the service menu of Sony portable Minidisc players.
USE THIS INFO AT YOUR OWN RISK !!!
The bits indicated in red are dangerous to set in my opinion, since they disable a lot of functions and make it hard to get back into the service menu again. Bits indicated in orange are less dangerous, but can be annoying and it is useless to change them.
