And here`s a step-by-step way to do the hack, just to clarify some stuff:
1: Entering Service Mode:
Set the "HOLD" switch on.
While holding down the VOL - key like a SHIFT key, enter the key sequence:
>>| >>| |<< |<< >>| |<< >>| |<< | | | |
i.e. FF FF REW REW FF REW FF REW PAUSE PAUSE
Release All Keys
2: The display will alternately display the firmware version in the left display and a screen with all LCD segments lit at about half second intervals.
3: Let`s start changing settings (NOW BE REALLY CAREFUL, DO STRICTLY AS STATED HERE, YOU SAVE CHANGES WHEN YOU PRESS PAUSE!)
4: Press VOL + -- you should see "MANUAL" displayed on the left and "0 00" on the right.
5: Press PLAY -- you should see "Laser" on the left and "0 10" on the right.
6: Press VOL + 5 times -- you should see "F Code" on the left and "0 60" on the right.
7: Press PLAY -- the first 3 digits of the left display should be continuously incrementing. The last 2 digits of the left display are a value in memory that you want to change (it probably reads "A0" for the MZ-N707 and "??" for the MZ-N505, but write this number down!). You should see "0 61" on the right.
8: Press VOL + repeatedly until the last two digits of the left display read "FE" (you can press VOL - if you go past it).
9: Press PAUSE
10: You have now saved the changes you made to the first setting, now, lets get on with hacking the second value
11: Press PLAY -- you should again see incrementing numbers in the first 3 digits of the left display and "0 62" should appear in the right display. The last two digits of the left display are the value you want to change (it probably reads "50" for the MZ-N707 and "??" for the MZ-N505, but write this number down!).
12: Press VOL + repeatedly until this reads "7B" (you can press VOL - if you go past it).
13: Press PAUSE
14: You have now saved the changes to the second setting, and you`re finished with Service Mode
15: Exit Service mode, by removing power plug or battery.
16: Start you MD and check that it works OK ( If it doesn`t work, then try setting the values back to A0 and 50 or whatever your values were
17: Test out the new stuff: M-Timer, Line-out, set playback speed, mic sensitivity
Now I know it`s exactly the same as the first post here, but it`s more newbie-friendly with step-by-step, also please note that I don`t take any responsibility whatsoever for this hack. I don`t guarantee my cut`n paste to be error free.
Neither do I guarantee for your warranty!
