Hello everyone,

Today i bought a Philps NMS8250, but when i took it apart i found a mod that i can't identify.

Is there anybody who can tell me what this mod is doing? I don't see this on pictures on the internet, so i'm guessing it's a mod. I haven't turned on the computer, because i want to service it first :)

Kind regards,
Dennis de Haan

Wow that was fast Smile Thanks!

I found it in the manual. Did not expect this to be original from the factory Smile
