Feedback vibrations or "buzzes" are received only if you are in a "Posture Training Session" or a "Custom Training Session".
No posture feedback vibrations (also known as "buzzing") will be received during the "Posture Assessment Session" or when you are just wearing your Lumo Lift without starting a posture training session or a custom training session.
If you are within a "Custom Training Session" or a "Posture Training Session" and still do not receive the buzzes, based on the "Vibration Delay" you have set, please see the instructions below to troubleshoot:
The Lumo Lift Sensor is meant to vibrate and provide a single "buzz" when the user is slouching or a deviation from the calibrated posture is detected. If the Lift Sensor does not vibrate (i.e. buzz) when the user is in bad posture, please use the recommended steps below to troubleshoot the problem:
- Confirm that the sensor is charged fully. If the LED doesn’t flash green when the sensor button is pressed, charge the sensor.
- Please enable the option to "Calibrate via Sensor" and confirm that the sensor vibrates when the button is pressed. If it doesn’t, try a cradle reset: Place the sensor in the charging cradle, with the cradle connected to a USB power source (e.g. a USB port on a laptop, or a USB charging block). With the sensor in the cradle, press and hold the sensor button for 15-20 seconds or until the device LED flashes blue/ purple and vibrates once.
- Please start a new "Posture Training Session" or a "Custom Training Session". Be sure to check the "Vibration Delay" setting. If this value is set too high, you won’t get many posture feedback vibrations. Just to be clear, if the delay is set to 60 seconds, the sensor will not vibrate until you have been out of good posture for a continuous period of 60 seconds. For troubleshooting purposes, select 3 or 5 seconds.
- Get into good posture, press the sensor button once to Calibrate your sensor, or, "Calibrate" from the Lift App when there is a prompt, before you start your training session. Once you start your training session, slouch for longer than the "Vibration delay" setting used above. Does the sensor vibrate?
- If the sensor is charged and responds to a button press, and the sensor doesn’t provide feedback when you slouch, the issue may be because of the way the sensor is worn. Try the tips below:
- Please wear the Lumo Lift next to your collarbone, about an half-an-inch to an inch below it, mid-way between tip of shoulder and your neck. For exceptions to that rule, please see the note below.
- Please wear the Lumo Lift with snug-fitting clothes. Loose clothes cause inaccurate readings because the Lift ends up tracking your garment instead of your body. If you tend to wear loose-fitting clothes, we would suggest raising the placement of the Lift to be perched on top of the collarbone or just above it - to the point where it's sitting in a place on the garment that has less slack, and so follows your body posture, better.
Calibrate your Lift sensor often:
The main reason for inaccurate buzzing or lack of accurate buzzing is lack of alignment. You MUST align your Lumo Lift during your training session to get the best out of your Lift. Every time you enter into a posture you suspect you will be in, for a while during your training session, make sure you "Calibrate". You can either enable the "Calibrate via Sensor" option within Settings and press the Sensor once to "Calibrate" or alternatively, calibrate your sensor from the "Help" screen at anytime.
About the "Vibration delay":
In general, you want the delay to be set to 5, 10, or 15 seconds in the first few days of operation. Setting a shorter delay helps effect change on your current posture habits. After you've acquired desirable posture habits, you can always adjust the Vibration Delay to 45 or 60 seconds, but we would not recommend going above that. The idea is to get your Lift to buzz so it can help you change your current posture habits. And when it's set for too high, the sensor won’t provide feedback and you’ll not get the best out of your Lift.
- You can check what the sensor thinks your posture is by tapping on the "Real-time posture" option within your "Posture Training Session" or your "Custom Training Session" or by tapping on the "Help" screen.
After following all of the tips above, if you’re still not receiving posture feedback vibrations when expected, please reach out to Customer Support on firstname.lastname@example.org immediately.
