Setup
Powering the Device
The AQESO Blood Pressure Monitor offers dual power options for your convenience:
- Batteries: Insert the included 4 AAA batteries into the battery compartment located on the back of the device. Ensure correct polarity.
- USB Type-C Cable: Connect the provided USB Type-C cable to the monitor and a 5V 1A USB adapter (not included). The device is not rechargeable and requires a continuous power connection when using USB.

Cuff Selection and Placement
Selecting the correct cuff size is crucial for accurate readings. The monitor comes with three different cuff sizes to accommodate various arm circumferences:
- Small Cuff: 7"-9" (17-22 cm)
- Medium/Large Cuff: 9"-17" (22-43 cm)
- Extra Large Cuff: 13"-21" (33-53 cm)
Using 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. Measure your upper arm circumference to choose the most appropriate cuff.

To place the cuff correctly:
- Ensure the cuff fits snugly but not too tightly around your upper arm, approximately 2-3 cm above the elbow joint.
- Position the air tube to run down the center of your arm, aligning the brachial artery marker (if present on the cuff) over your artery.
- Rest your arm on a flat surface with your palm facing upwards, ensuring the cuff is at heart level.

Operating Instructions
Taking a Measurement
The AQESO Blood Pressure Monitor is designed for ease of use, especially for the elderly. Follow these steps to take a measurement:
- Sit comfortably with your back supported and feet flat on the floor. Avoid talking or moving during the measurement.
- Ensure the cuff is correctly placed on your arm as described in the Setup section.
- Press the large START/STOP button. The monitor will automatically inflate the cuff and begin the measurement.
- Remain still until the measurement is complete and your systolic, diastolic, and pulse readings are displayed on the large backlit LCD screen.
- Press the START/STOP button again to turn off the device.

User Profiles and Memory
The monitor supports three independent user profiles (A, B, C), each capable of storing up to 500 measurements. This allows multiple family members to track their blood pressure trends over time.
- Selecting a User: Before taking a measurement, use the user selection buttons (A/B/C) to choose the desired profile.
- Viewing Historical Data: Press the MEM button to access the stored readings for the selected user. You can navigate through the records using the appropriate buttons (refer to the full user manual for detailed navigation). Each record includes the date and time of the measurement.

Understanding Your Readings
The monitor displays your systolic (upper number), diastolic (lower number), and pulse rate. It also features a colorful WHO (World Health Organization) classification bar on the left side of the display, which visually indicates your blood pressure category:
- Green: Normal Pressure
- Yellow: High-Normal Pressure
- Red: Serious Pressure

The AQESO monitor utilizes an upgraded ASP (Accurate Signal Processing) core algorithm, which has been developed and tested with over 100,000 clinical data points. This advanced algorithm ensures faster, more reliable, and adaptable readings tailored to different body types and conditions.

Maintenance
To ensure the longevity and accuracy of your AQESO Blood Pressure Machine, follow these maintenance guidelines:
- Cleaning: Wipe the monitor and cuffs with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the device in the provided carrying 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 display. Remove batteries if the device will not be used for an extended period.
- Cuff Care: Handle the cuffs gently. Avoid sharp objects or excessive pulling that could damage the air bladder or tubing.
