4. Operating Instructions
4.1. Choosing the Correct Cuff Size
Using the correct cuff size is essential for accurate readings. Measure your upper arm circumference at the midpoint between your elbow and shoulder.
| Arm Circumference | Cuff Size |
|---|---|
| 9" - 17" (22-43 cm) | Medium/Large |
| 13" - 21" (33-53 cm) | Extra Large |

This image displays the main blood pressure monitor unit alongside both the Medium/Large and Extra Large cuffs, highlighting the flexibility for different arm sizes.

This graphic illustrates why proper cuff sizing is critical. It shows that a cuff that is too small can result in falsely high readings, while a cuff that is too large can lead to falsely low readings. It also depicts arms of medium/standard, large, and extra-large sizes, indicating the appropriate cuff for each.
4.2. Applying the Cuff
- Connect the cuff's air tube securely to the air socket on the side of the monitor.
- Sit comfortably with your back straight and supported, feet flat on the floor, and legs uncrossed.
- Place your arm on a flat surface, palm facing up, ensuring your arm is at heart level.
- Slide the correct size cuff onto your bare upper left arm, approximately 1-2 cm above the elbow joint. The air tube should run down the center of your arm.
- Ensure the cuff is snug but not too tight (you should be able to insert two fingers between the cuff and your arm).

This image provides a visual guide on how to correctly position yourself and the cuff for a blood pressure measurement. It shows a person sitting upright with their back supported, feet flat on the floor, and the arm resting on a table at heart level, with the cuff properly placed on the upper arm.
4.3. Taking a Measurement
- Once the cuff is correctly applied and you are in the proper posture, press the START/STOP button.
- The cuff will automatically inflate and then slowly deflate.
- Your systolic, diastolic, and pulse rate will be displayed on the large backlit LCD screen.
- The monitor will automatically store the reading under the selected user profile.
- The color indicator light on the monitor will show your blood pressure category (Green for Normal, Yellow for High-Normal, Red for Serious Pressure).

This image shows the blood pressure monitor in operation, with a hand pressing the START/STOP button. The large, backlit LCD screen clearly displays the systolic and diastolic readings, along with the pulse rate. The green indicator light is also visible, signifying a normal blood pressure reading.
4.4. Reviewing Stored Measurements
To review previous measurements for the currently selected user:
- Ensure the machine is turned off.
- Press the MEM button. The most recent reading will be displayed.
- Press MEM again to cycle through older readings.
- To exit memory mode, press the START/STOP button or wait for the device to automatically turn off.
5. Maintenance
- Cleaning: Wipe the monitor and cuff with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the device in the provided drawstring bag in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace all four AAA batteries when the low battery indicator appears on the screen. If the device will not be used for an extended period (e.g., 3 months or more), remove the batteries to prevent leakage.
- Cuff Care: Ensure the cuff is not twisted or kinked during storage. Avoid sharp objects that could puncture the cuff.
