The calibration process serves to teach your UPRIGHT GO what your upright (i.e. straight) posture is. It is important to calibrate your UPRIGHT GO every time you put it on your back. If you're about to spend the majority of your day sitting, you should calibrate while sitting. Otherwise, calibrate while standing. You can repeat this step whenever you feel that your slouch position is not properly identified.
HOW TO CALIBRATE
Calibrating your device is very simple and only takes 2 seconds. It can be done either from the app or from the UPRIGHT GO itself, as follows:
• Move into your upright posture and stay still for calibration.
• Double click the power button, or tap CALIBRATION on the app's main screen.
• UPRIGHT GO will immediately respond with two short vibrations.
