Powering up for the first time & the automatic throttle calibration

The KAVAN ESC features Automatic Throttle Calibration to ensure the smoothest throttle response and resolution throughout the entire throttle range of your transmitter. This step has to be performed just once to allow the ESC to "learn and memorize" the throttle output signal of your transmitter. It only needs to be repeated if you change your transmitter.
