BioDrive® Signal Is Weak or Stops Mid-Session

If BioDrive® loses or shows a weak signal during a session, work through these steps.

Step 1: Finger Sensor Fit & Placement

1. Place the pulse oximeter fully on the finger (snug, not tight).
2. Warm your hands, cold fingers reduce signal quality.
3. Keep your hand relaxed and still on the armrest.

Step 2: Re-seat the Sensor

1. Remove the sensor from your finger, wait 5–10 seconds, re-apply.
2. If you see an indicator on the control/app screen, confirm it’s receiving a pulse.

Step 3: Stable Breathing

• Breathe in a smooth rhythm (slow inhale, longer exhale) to help stabilize readings.

Step 4: Cable & Power Check (Control Box / Pro)

• Ensure sensor cable is fully inserted into the ShiftLink and control knob.
• Check chair power and, for Pro, that ShiftLink and USB-C cables are fully seated.

Step 5: Restart BioDrive®

• Toggle BioDrive® off → on in the app or via the control box button.
• If needed, restart the session.

Step 6: Try Another Finger

• Some users get better signal on the index or middle finger of the non-dominant hand.

After You Fix It

Run a short BioDrive® session and watch the indicator, steady tracking should hold for the full session.
