Note: The device cannot be used while charging.
3.2 Blood Pressure Measurement
3.2.1 Before Taking Measurements
To help ensure accurate measurements, follow these directions:

  • Rest for at least 5 minutes before taking measurements. Stress raises blood pressure.
  • Avoid taking measurements when stressed.
  • Remove any tight-fitting clothing from your arm.
  • A single measurement does not provide an accurate indication of your true blood pressure.
  • You need to take and record several results over a period of time.
  • Try to measure your blood pressure at the same time each day to maintain consistency.

3.2.2 Applying the Arm Cuff

  1. Wrap the cuff around the upper arm, about 1 to 2 cm above the elbow joint, as shown.
  2. Place the cuff directly against the skin, as clothing may cause a faint pulse and result in measurement errors.
  3. Constriction of the upper arm, caused by rolling up a shirtsleeve, may prevent accurate readings.
  4. Confirm that the artery position mark is lined up with the artery.

Note keep the host wear position aligned with the middle finger.

3.2.3 Sitting Correctly
To take measurements, you need to be relaxed and comfortably seated. Sit in a chair with your legs uncrossed and your feet flat on the floor. Place your arm on a table, so that the cuff is level with your heart. 3.2.4 Measuring Blood Pressu re

  1. Power on the blood pressure monitor.
  2. Press the Start/Stop button to start taking blood pressure measurements.
  3. The monitor will automatically deflate the cuff slowly while taking measurements. A typical measurement takes about 30s.
  4. The readings will be displayed when the measurement is finished. 11

You can press Start/Stop button again to stop the blood pressure measurement.
Note: While taking measurements, you should remain still and not squeeze the cuff.
3.2.5 After Taking Measurements
The monitor will automatically release the gas in the cuff once finished taking measurements. Press the button to turn the power off after taking measurements. Remove the cuff.
Note: The device has an automatic power shut-off function, which turns off the power automatically 2 minutes after taking measurements.
3.3 Recording ECG
3.3.1 Before Taking Measurements
To help ensure accurate measurements, follow these directions:

  • Before using the ECG function, pay attention to the following points to obtain precise measurements.
  • The ECG electrode must be positioned directly against the skin.
  • If your skin or hands are dry, moisten them using a damp cloth before taking measurements.
  • If the ECG electrodes are dirty, remove the dirt using a soft cloth or cotton swab dampened with disinfection alcohol.
  • While taking measurements, do not touch your body with the hand with which you are taking measurements.
  • Please note that there must be no skin-to-skin contact between your right and left hand. Otherwise, the measurements cannot be taken correctly.
  • Stay still while taking measurements, do not speak, and hold the device still.
  • Movements of any kind will falsify measurements.
  • If possible, take measurements when sitting and not when standing.
  • Follow the text and voice guides on your phone to finish taking measurements.
