Hi, Is there anyway in unlocking the full volume potential of the NWZ-S618F walkman, because when the volume is on 20, it barely increases untill 30. Also I have found the test mode file for the NWZ-A82XX series (bluetooth walkmans) and this testmode work's on the NWZ-S618F walkman. But there must be a way to make the NWZ-S618F to Japanese spec as this is much louder than the UK spec, as a friend of mine has the Japanese version. The testmode pdf can be downloaded from - http://rapidshare.com/files/117596728/NWZ-A826.pdf This link works. Also, look at the following attachment Please advise as there must be way to make the volume louder.
