5. Operating Instructions
5.1. Before Taking a Measurement
- Avoid eating, drinking alcohol, smoking, or exercising for at least 30 minutes before measurement.
- Rest for 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 flat surface so the cuff is at heart level.
5.2. Applying the Arm Cuff
- Slide your left arm through the cuff loop. The air tube should run down the inside of your arm.
- Position the cuff so the bottom edge is approximately 1-2 cm (0.4-0.8 inches) above your elbow. The artery mark on the cuff should align with your brachial artery.
- Wrap the cuff snugly around your upper arm, securing it with the hook-and-loop fastener. Ensure it is not too tight or too loose.

5.3. Taking a Measurement
- With the cuff correctly applied and your arm positioned, press the START button.
- The cuff will automatically inflate to a suitable level. The monitor uses advanced technology to customize inflation for comfort.
- Once inflation is complete, the cuff will slowly deflate, and your blood pressure (systolic and diastolic) and pulse rate will be displayed on the large LCD screen.
- The monitor will also display a colored gauge next to the readings to help interpret the result.
- If an irregular heartbeat is detected, an indicator will appear on the display.
- The measurement will automatically be stored in the device's memory.
- To stop a measurement at any time, press the START button again.

5.4. Understanding Your Readings
The display shows:
- SYS (Systolic Pressure): The top number, indicating the pressure in your arteries when your heart beats.
- DIA (Diastolic Pressure): The bottom number, indicating the pressure in your arteries between beats.
- PUL (Pulse Rate): Your heart rate, measured in beats per minute.
- Irregular Heartbeat Indicator: Appears if an irregular heartbeat is detected during the measurement.
- Colored Gauge: Provides a visual reference for your blood pressure category based on established guidelines.
Always consult your doctor for interpretation of your blood pressure readings.
