4.4 Understanding Your Results
The monitor displays three key values:
- SYS (Systolic Pressure): The highest pressure in your arteries when your heart beats.
- DIA (Diastolic Pressure): The lowest pressure in your arteries when your heart rests between beats.
- PUL (Pulse Rate): Your heart rate, measured in beats per minute.
The device also features a traffic light color scale on the left side of the display for easy classification of your blood pressure results according to WHO guidelines.

4.7 Irregular Heartbeat Detection
The monitor can detect and indicate possible pulse arrhythmias. If an irregular heartbeat symbol appears on the display, consult your physician for evaluation. Only a medical professional can assess the type and severity of an arrhythmia.
4.8 Motion Detector
To ensure accurate measurement results, the BU 586 Voice includes a motion detector. If excessive movement is detected during measurement, an error symbol will appear, indicating a potential application error. This helps ensure more precise readings.
