Press the A.T. mode button on the controller to set the handpiece into Auto-Torque mode:
- First Stage (60% output): The A.T. mode indicator shows a breathing light.
- Second Stage (100% output): The A.T. mode indicator shows a constant light.
Press the A.T. mode button to cycle through the first and second stages, as well as to turn off the mode.
Self-Calibration Mode
Step 1: Set the speed control knob to the lowest setting and ensure the main power switch on the controller is off (power off).
Step 2: Plug the controller into the power outlet.
Step 3: Connect the handpiece to the controller and turn on the power switch on the handpiece. (At this point, the motor is still stationary.)
After completing the above steps, hold down the A.T. mode button and turn on the main power switch on the controller. The motor of the handpiece will start running, and the A.T. mode indicator will start blinking. Do not move or apply resistance to the handpiece (running motor) until the A.T. mode indicator turns off. Once this happens, you can start using it. The self-calibration takes about 5 to 8 seconds.
