Does anybody have the proper manual for mystery blue series 30 amps ESC.   

The manual which came with mine doesn't make any sense. Its noted in the manual that it will make three beeps but mine is making 4 beeps. Also the order is all messed up. The manual shows lipo setting will be second but the lipo setting is coming somewhere at the end out of the 10 options.

Forget the manual.
Here is the sequence I am using:

1) _ _ * * (longer pause) --pull back during the pause to toggle brake

2) _ _ , _ _ , _ _ , _ _ , _ _ = 2S lipo

3) _ _ _ , _ _ _ , _ _ _ , _ _ _ , _ _ _ = 3S lipo

Some ESCs (but not all of them) have the following settings.

3A) _ _ _ _ , _ _ _ _ , _ _ _ _ , _ _ _ _ , _ _ _ _ = not sure.. possibly a NiMH battery?

3B) _ _ _ _ _ , _ _ _ _ _ , _ _ _ _ _ , _ _ _ _ _ , _ _ _ _ _ = not sure.. possibly a NiMH battery?

4) ___ , ___ , ___ , ___ , ___ = Auto battery detect possibly. Works with my 2S or 3S

5) _ * , _ * , _ * , _ * , _ * = Battery protection reduce power

6) * _ , * _ , * _ , * _ , * _ = Battery protection hard cut off

7) _ ** , _ ** , _ ** , _ ** , _ ** = Battery protection ignore

8) WWW , WWW , WWW , WWW , WWW = Reverse

9) WW , WW , WW , WW , WW = Accel soft Heli mode

10) W , W , W , W , W = Accel normal Airplane mode

11) * , * , * , * , * = Timing Auto possibly?

12) ** , ** , ** , ** , ** = Timing soft possibly?

13) *** , *** , *** , *** , *** = High timing possibly?

14) \ , \ , \ , \ , \ = 8 Khz possibly?

15) / , / , / , / , / = 16 Khz possibly?

16) _ , _ , _ , _ , _ = Appears to be restore default

17) _*_ , _*_ , _*_ , _*_ , _*_ = Governor off possibly

18) _**_ , _**_ , _**_ , _**_ , _**_ = Governor Heli 1 possibly

19) _***_ , _***_ , _***_ , _***_ , _***_ = Governor Heli2 possibly

20) _****_ , _****_ , _****_ , _****_ , _****_ = Governor possibly

Excellent SunLikeStar . I checked my ESC sounds its exactly as you have given here(except 3a & 3b. its not there).

why you have given possibly here ? where exactly you got this from?

from some forum discussion, maybe from rcgrups, long time ago. the file was on my desktop because i reprogrammed my esc yesterday

Nice is this only for mystery blue series ESC or all bec's behave in this same way?

only for mystery 30A blue series.

I was trying to program the ESC for low voltage cut off. But its not listed.
So the mystery blue series does not suppost low voltage cut off setting?
At what volt of the battery is it cutting off?

You cannot set cutoff voltage but you can select how it cuts (reduce power or hard cut). I always use reduce power setting. On reduce power setting i tested the battery and it was 3.3v each cell.

Thank you SunLikeStar...
