Taking a Measurement

Follow these steps for a proper reading.

Sit comfortably on a chair with feet flat on the floor and back supported.
Rest your arm on a table so the cuff is at heart level. Palm should be facing up.
Ensure the cuff is correctly applied (see Initial Setup).
Press the START/STOP button. The monitor will inflate automatically.
Remain still and silent until measurement is complete and results are displayed.
The monitor will automatically deflate. Your systolic, diastolic, and pulse readings will show.
To turn off the device, press START/STOP again. It will auto-power-off after 1 minute of inactivity.

WARNING! Do not inflate the cuff when it is not wrapped around your arm.

Understanding Your Readings

The display shows key information.

Systolic Pressure: Top number (e.g., 120). Pressure when heart beats.
Diastolic Pressure: Bottom number (e.g., 80). Pressure when heart rests between beats.
Pulse Rate: Beats per minute (e.g., 72).
Irregular Heartbeat Icon: Appears if an irregular rhythm is detected during measurement. Consult your physician if it appears frequently.
Hypertension Indicator: A bar graph on the side of the display lights up if your systolic reading is 135 mmHg or higher, or diastolic is 85 mmHg or higher (based on home monitoring guidelines).

Refer to the classification chart in the manual or consult your doctor to understand your blood pressure category.

Memory Function
