1. Step by Step

1. Turn on the mTiny and tap pen first.
2. Press the power button and the down button (i.e. buttons 1 and 3 in the figure below) of the tap pen at the same time. When you feel the vibration and the tap pen indicator light turns to blink blue and green alternately, it enters the calibration mode.

 

3. The order of calibration is up, down, left and right in that order, and the procedure is as follows:

a. Push the joystick up to the end, and then release it to let the joystick return to its home position. Push the joystick fully forward and then release it.

b. When calibrating downward, you also need to push joystick down to the end, and then release it to return to the position. The steps for left and right are the same as above. 

c. The steps for left and right are the same as above. After calibration is completed, press and hold the power button and down button of the tap pen at the same time to exit the calibration mode.
