5. Operating Instructions
5.1 Before Taking a Measurement
- Avoid eating, drinking alcohol, smoking, exercising, and bathing for 30 minutes before measurement.
- Rest for at least 15 minutes before taking a measurement.
- Sit in a chair with your feet flat on the floor and your back supported.
- Place your arm on a table so the cuff is at heart level.
5.2 Applying the Arm Cuff
- Wrap the cuff around your upper arm, approximately 1-2 cm above your elbow.
- Ensure the air tube is centered on the inside of your arm and points down towards your hand.
- The cuff should be snug but not too tight. You should be able to insert two fingers between the cuff and your arm.

5.3 Taking a Measurement
- Press the START/STOP button. The cuff will begin to inflate automatically.
- Remain still and silent during the measurement.
- Once the measurement is complete, the cuff will deflate, and your systolic pressure, diastolic pressure, and pulse rate will be displayed on the screen.
- Press the START/STOP button again to turn off the monitor. The monitor will automatically turn off after 2 minutes of inactivity.
5.4 Understanding Your Readings
The display shows three main 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.
- PULSE: Your heart rate, or the number of times your heart beats per minute.
The monitor may also display indicators for irregular heartbeat or body movement during measurement. Consult your doctor for interpretation of your blood pressure readings.
