Setup
1. Battery Installation
The UA-651BLE operates on 4 AA batteries, which are included. Locate the battery compartment on the back of the monitor. Insert the batteries, ensuring correct polarity (+/-) as indicated inside the compartment. Close the battery cover securely.
2. App Pairing (A&D Heart Track App)
To utilize the Bluetooth features and track unlimited measurements, download the free A&D Heart Track App from the iOS App Store (requires iOS 12.0 or later) or Google Play Store (requires Android 5.0 or above). Follow the in-app instructions to create an account and pair your UA-651BLE monitor. The app allows for seamless data synchronization and health tracking.

Measuring Cuff Size
Using the correct cuff size is crucial for accurate blood pressure readings. An ill-fitting cuff can lead to inaccurate results. Follow these steps to determine your appropriate cuff size:
- Find Your Midpoint: Allow your arm to hang naturally at your side. Locate the bony part of your shoulder (acromion process) and the bony part of your elbow (olecranon process). Measure the distance between these two points and divide by two to find the midpoint of your upper arm.
- Measure Your Arm Circumference: At the midpoint you just identified, measure the circumference of your arm using a tape measure.
- Choose the Correct Cuff Size: Refer to the table below to select the recommended cuff size based on your arm circumference. The UA-651BLE comes with a Standard Wide Range Adult cuff (8.6-16.5" / 22-42cm). If your arm circumference falls outside this range, you may need to purchase an alternative cuff (Small, Medium, or Large) separately.
Figure 3: Instructions for measuring arm circumference. This diagram illustrates how to find the midpoint between the shoulder and elbow, and then measure the arm's circumference at that point to ensure proper cuff fit.
Recommended Cuff Sizes for A&D BP Monitor
| Arm Circumference (cm) | Arm Circumference (in) | Category |
|---|---|---|
| 16-24 | 6.3-9.4 | Small Adult |
| 22-42 | 8.6-16.5 | Standard Wide Range Adult |
| 23-37 | 9.0-14.6 | Medium Adult |
| 31-45 | 12.2-17.7 | Large Adult |

Video 1: "A&D Medical 5 Blood Pressure Cuff Mistakes to Avoid". This video provides essential guidance on how to correctly measure your arm for proper cuff sizing, how to correctly place the cuff, and other common mistakes to avoid for accurate blood pressure readings. It highlights the importance of correct cuff fit and position.
Operating Instructions
1. Proper Cuff Placement
Correct cuff placement is vital for accurate readings. Ensure the cuff is placed on the bare skin of your left arm, approximately 1-2 cm (0.5 inches) above the elbow. The palm of your hand should be facing upwards. The cuff should be snug enough that you can just about fit two fingers underneath it. If it's too loose or too tight, it will affect accuracy. The tube should run down your arm, aligned with your middle finger, and connect to the monitor.
Figure 5: Step-by-step guide for proper cuff placement. This visual aid shows how to wrap the cuff on bare skin, ensure it's secured with enough room for two fingers, and position your arm correctly at heart level before taking a measurement.
2. Taking a Measurement
Once the cuff is correctly positioned, sit comfortably with your back supported and feet flat on the floor. Your arm should be resting on a flat surface, with the cuff at heart level. Press the START button on the monitor. The cuff will automatically inflate and then slowly deflate, displaying your systolic, diastolic, and pulse rate readings on the large digital LCD screen.
3. Important Considerations for Accurate Readings
For the most accurate blood pressure measurements, observe the following guidelines:
- Avoid caffeine, alcohol, smoking, and strenuous exercise for at least 30 minutes prior to measurement.
- Rest quietly for 5 minutes before taking a reading.
- Ensure your arm is relaxed and supported at heart level.
- Do not talk or move during the measurement.
- Take multiple readings (e.g., two or three) with a short break in between and average them for a more reliable result.

Maintenance
Proper maintenance ensures the longevity and accuracy of your blood pressure monitor:
- Cleaning: Wipe the monitor and cuff with a soft, dry cloth. If necessary, use a cloth lightly dampened with water and a mild soap, then wipe dry immediately. Do not use abrasive cleaners or immerse the unit in water.
- Storage: Store the device in its carrying case in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity.
- Battery Replacement: Replace all four AA batteries when the low battery indicator appears on the display. Do not mix old and new batteries or different types of batteries.
