4. Operating the Monitor
4.1 Before Taking a Measurement
- Avoid eating, drinking alcohol or caffeine, smoking, and exercising for 30 minutes before measurement.
- Rest for at least 5 minutes before taking a measurement.
- Sit upright 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.
4.2 Applying the Arm Cuff
- Wrap the cuff around your upper left arm. The air tube should run down the inside of your arm and be aligned with your middle finger.
- The bottom edge of the cuff should be 1 to 2 cm above your elbow.
- Ensure the cuff is snug but not too tight. You should be able to insert two fingers between the cuff and your arm.

4.3 Taking a Measurement
- Press the START/STOP button. The cuff will begin to inflate automatically.
- Remain still and do not talk during the measurement.
- Once the measurement is complete, the cuff will deflate, and your systolic pressure (SYS), diastolic pressure (DIA), and pulse rate will be displayed on the screen.
- Press the START/STOP button again to turn off the monitor. If you forget, it will automatically shut off after 2 minutes.

- DIA (Diastolic Pressure): The lowest pressure in your arteries when your heart rests between beats.
- PULSE: Your heart rate, measured in beats per minute.
