 Using the Product

Charge the Battery
Use the USB cable to charge the product. Connect the USB cable to a USB charger or to the PC. A full charge will need 2 hours. When the battery is charged fully the indicator will be blue. The product works with very low power consumption and one charge usually works for months. On-screen battery symbols which indicate the battery status can be seen on the screen.

Note: The product cannot be used during charging, and if choosing a third-party charging adaptor, select one that complies with IEC60950 or IEC60601-1.
 Measure Blood Pressure
 Applying the arm cuff

  1.  Wrap the cuff around the upper arm, about 1 to 2 cm above the inside of the elbow, as shown.
  2.  Place the cuff directly against the skin, as clothing may cause a faint pulse and result in a measurement error.
  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.

 How to sit correctly
To take a measurement, 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 left arm on a table so the cuff is level with your heart.
