or was not able to signal proper status, so to prevent motor or other
damage, the ESC reset itself. Check for moisture problems or strong fields
right next to the ESC. If nothing is found, the MCU may be faulty.
Once a valid input is connected and the ESC is sees an idle power
request, a long beep 4 is played and the green LED lit to indicate that the
ESC is armed. This is required for all input sources, and must be
maintained at a rate of at least 20Hz, or power will be switched off. If the
input signal stops, the ESC will disarm after 2 seconds and play beeps 3
and 2 to indicate that the input disappeared. The ESC will look again for
valid input sources, or programming input via the Turnigy USB linker.
If no input is detected for more than 8 seconds, a periodic beep 3 every 3
seconds will be emitted (beacon mode). This may aid in the location of a
crash, assuming the signal is lost.
