How to Properly Wear an ALEX

1) ALEX should be located at a horizontal angle to a center hairline in the back of your neck. After
wearing it, adjust the length of legs to place them at a horizontal angle to the end hairline in the
center of your neck in order to help ALEX properly operate.

2) The overall sides of sensor in ALEX should touch the back of your neck. It fails to accurately

measure your posture if sensor is lean on one side or is not properly touching the neck.

3) Run AVATAR mode in the application to check if you properly wear an ALEX. Move your neck to

front or back to check if AVATAR is properly working.

(Good)

(Bad)

Improper Wearing of ALEX

1) If sensor is slanted, or higher or lower than the end hairline

2) If sensor is being pressed due to tightly worn device

3) If device is not properly fit into the neck so it is not touching the surface of your neck, or only the

upper side of sensor is touching the neck
