There have been a number of queries regarding the beep codes for the Phantom and the Remote controls.  I had trouble myself trying to find any information about the warning/alert sounds that come from the Phantom itself and I eventually found this ESC Sound Introduction from the Phantom 1 manual (PHANTOM_Quick_Start_Manual_v1.7_en.pdf dated 2013-09-25)  It didn't seem to make it into the Phantom 2 series manuals.

Updated v2

And I find the same imformation in the E300 manual.
I think the logic determining how ESC indicate its status by making a sound could be the same of E300 and E310.
Im going to ask more imformation and report it to the manual editor.

Hi Gil,
Got another information of beep codes for E310.
If the warning sound is like "BBB---BBB---BBB---", It indicate that the motor parameters don’t match the firmware data saved in the ESC.
I've reported it and hope they can update the manual of Phantoms.

Thanks for this...very helpful! I have red flashing and b-b-b and no remote connectivity. Twice flown, no crashes. LOTS OF ISSUES!
