Using Your New ESC
Improper polarity or short circuit will damage the ESC therefore it is your responsibility to double check
all plugs for proper polarity and firm fit BEFORE connecting the battery pack.
Alert Tones
The ESC is equipped with audible alert tones to indicate abnormal conditions at power up.
If the ESC can't enter into working mode after powering up, it indicates that you have not setup throttle
calibration.
1. Continuous beeping tone (****) – Indicates that throttle stick is not in the minimum position.
2. Single beeping tone followed by a one second pause (* * * *) – Indicates that the battery pack
voltage is not within the acceptable range. (The ESC automatically checks and verifies the battery
voltage once the battery is connected).
3. A single beeping tone followed by a short pause (* * * *) – Indicates that the ESC is unable to
detect the normal throttle signal from the receiver.
