You may find the volume restrictions on your shiny new sexy NWA 1000 / 3000 a bit restrictive. In a loud environment, i.e a train or outside, the volume isn't quite loud enough.
Thankfully, Sony understand not everyone wants to conform with EU regulations. So there is a simple modification which unlocks those extra decibels.
Heres how to do it. Firstly, you need to enter your NWA1000/3000 into test mode.

Then, alter the setting accordingly.

Now you will find your volume goes much, much higher. Also, avoid using the Equaliser if possible as the Equaliser lowers the volume significantly.
Good luck, and happy listening. Remember, always operate at a safe volume. Do not operate your Walkman at maximum volume if you have performed this modification.
