Remote Control Handle Rocker Calibration
Hold the remote control without touching the rocker, press the upper buttons F1 and F3 on the remote control and
release them at the same time. At this time, the remote control will emit a continuous "beep~beep~" sound (1 time/sec)
to indicate that it has entered the calibration mode. After entering the calibration mode, the users need to turn the left and
right rockers to full rudder and rotate several times until the sound of "beep~beep~" stops, and the calibration is ready.
Press F3 once to make the calibration take effect and complete the calibration.

Attention! When calibrating the remote rod, please do not touch the rocker before calibration. The rocker can only be
moved after entering the calibration mode.
Remote Control Turnon/Turnoff
 Turn on the remote control: Shortly press the power button once, then long press the power button for more
than 2 seconds, and hear a "beep”, which means the remote control is turned on.
 Turn off the remote control: Shortly press the power button once, then long press the power button for more
than 2 seconds, and hear three “beeps”, which means the remote control is turned off.
