8. Device automatically stores measurement with timestamp.
9. To turn off: Press START/STOP or wait for auto shut-off.

Tip: Avoid eating, smoking, or exercising for 30 minutes before measurement.

AFIB Detection Feature

The device screens for possible atrial fibrillation during each measurement.

1. During measurement: Device analyzes pulse rhythm for irregularities.
2. AFIB symbol: Appears on display if atrial fibrillation pattern is detected.
3. Accuracy: Clinical studies show high sensitivity for AFIB detection.
4. Important: AFIB detection is a screening tool, not a diagnosis.
5. Action required: If AFIB symbol appears repeatedly, consult physician.
6. Note: Some irregular heartbeats may trigger symbol without AFIB present.

WARNING! Do not rely solely on device for AFIB diagnosis. Always consult healthcare professional.
