where can i find Phantom 2 beep codes?

OK, let me expand a little. I had a faulty motor or ESC so I changed both, everything works OK, it flies well but there is one problem: as soon as I start the Phantom the new ESC beeps four times and the associated LEDs flash flash four times. That's it, everything proceeds normally. So, what do the beeps mean? Does the new ESC need to be calibrated?

The new ESC/motor is the only one beeping?
Or do they all beep?
They all should beep (it happening simultaneously can make it hard to tell).
The DJI ESCs do not calibrate.
They are set to work right out of the box.
If everything flies well, you're probably okay...
Don't place too much weight on the beep pattern.
It's just a start-up sequence that is sometimes affected/modified by firmware upgrades.

Just the new ESC/motor does the initial four beeps. I plan to watch that motor and portion of the arm with a heat gun after flights, will not be concerned if temps are normal.
Many thanks

Oh let me know if you ever figure out the issue.
