How Do I Take Demo Mode Off NWZ-S638F?

[sharvale]

I have bought a secondhand Sony NWZ-S638F Walkman and the home screen says "Demo" I have looked all over the internet and asked Sony to try and find how to put it back to normal, to no avail.  Can anybody solve this mystery I am sure it can only be a case of pressing buttons in a particular order.

Or does anyone know where I can download the service manual (not user manual) for free in case it is in there?

Many thanks in anticipation
