● The warning tone: the warning tone is set as
audible sound to help users judge abnormal condition after turn
on the power.
1. Fail to enter working mode after turn on the power: the routine of throttle has not been set yet.
2. Continuing beeps: the pull rod of throttle is not in the lowest position
3. There is a short pause after a beep: the ESC can not detect normal throttle signals from receiver.
4. There is a pause of one second after a beep: the voltage of battery pack is out of acceptable limit (once
the battery is connected, the ESC will carry out a self-checking and check the voltage of battery.)

The smart protection functions of ESC.
The introduction of the protection function in the ESC for brushless motor
Types of
protection
Descriptions of protection
Protection
for startup
If the motor fails to startup normally in two seconds after push the throttle to start, the ESC will
cut off the motor. The throttle shall be reset to commence a restart. Possible reasons: there is a
disconnection or poor contact in wiring between the ESC and motor. The propeller is stemmed by
other objects. The speed reduction gear is badly blocked.
Protection
for
temperature
When the working temperature in the ESC is higher than 100 , the ESC will reduce the output
℃
power automatically to commence protection, but will reduce the output power to 40% of full
power to reserve some power for motor and avoid crash landing instead of turning off all output
power. The ESC will recover to max power as the temperature falls.
Protection
for lost of
throttle
signals
The ESC will reduce the output power to motor when the ESC detect that there are 2 seconds’ lost
of throttle signals. If there another 2 seconds’ lost of throttle signals, the ESC will cut off motor
automatically. If the throttle signals recover during the reduction of output power of motor, the
ESC will recover control of throttle at once. In this method, in the case of momentary lost of
signals (within 2 seconds), the ESC will not commence the protection of throttle. Only when the
control signals have been lost for a long time, the ESC will commence protection. However, the
ECS will reduce the output power gradually instead of cutting off output power immediately so
that the players will have certain period to rescue the machine. It has both safety and practicability.

The routine of throttle shall be set at the first time turn on the ESC.
The feature of HobbyKing ESC is to set best routine of throttle according to different transmitters. The
ESC can obtain most stable throttle linear response through the total routine of throttle in transmitters. The
objective is let the ESC to obtain and remember the output signals of throttle in transmitters. The operation
needs to be carried for one time. Please repeat the operation when change transmitters.
Notice: must to check carefully whether polarities of all connector assembly are correct and whether the
installation is firm before connect the battery pack during the using to avoid damages to the ESC due to
incorrect connection between polarities or short cut.
The operation when use the ESC for the first time is as follows:
● The normal startup procedure of the ESC is as follows:
