Operating Instructions
Preparing for Measurement:

- Rest for at least 5 minutes before taking a measurement.
- Sit in a comfortable position with your back supported and feet flat on the floor.
- Place your arm on a table so the cuff is at heart level.
How to Measure Your Blood Pressure:
Wrap the cuff on your left arm: Ensure the cuff is snug but not too tight, keeping it level with your heart.

Position the cuff correctly: The cuff should be approximately 0.8-1.2 inches (2-3 cm) above the elbow joint.

Once the measurement is complete, your systolic pressure (SYS), diastolic pressure (DIA), and pulse rate (PUL) will be displayed on the screen. The device will automatically store the reading.
Understanding Your Readings:
Blood pressure readings are typically presented as two numbers: systolic (the top number) and diastolic (the bottom number). The pulse rate indicates your heart beats per minute.
