1. Turn on transmitter, move throttle stick to top position, connect battery pack to ESC and wait for 2 seconds until you hear "toot-toot-" emits.
2. The tone of "toot-toot-" will repeat for 4 times, within these times, move the throttle stick to bottom position, the motor emits special tones, means the setting of throttle range is completed. After 1 second, the system will enter the battery cells confirmation program and emit "123" for system OK tones.
Note: In order to make ESC compatible with your transmitter's throttle range, if you use this ESC for the first time or if you change to use other transmitter, you must reset the throttle range by following above mentioned steps。
