3. Setup

3.1 Battery Installation

The Microlife 3AG1 operates on batteries. Ensure fresh batteries are installed correctly before first use.

1. Open the battery compartment cover on the back of the main unit.
2. Insert the required number of batteries (typically AA size, refer to the compartment for exact type and quantity) according to the polarity indicators (+ and -).
3. Close the battery compartment cover securely.
4. The battery check function will indicate battery status on the display. Replace batteries when the low battery indicator appears.

3.2 Cuff Attachment

Proper cuff placement is crucial for accurate readings.

1. Connect the air tube from the cuff securely into the air jack on the side of the main unit.
2. Place the cuff on your bare upper arm, approximately 2-3 cm above the elbow joint. The artery mark on the cuff should align with your brachial artery (inner side of the arm).
3. Ensure the cuff is snug but not too tight. You should be able to fit two fingers comfortably under the cuff.
4. The bottom edge of the cuff should be about 2 cm above the elbow.

4. Operating Instructions

4.1 Taking a Measurement

The Microlife 3AG1 features one-touch operation for ease of use.

1. Sit comfortably with your back supported and feet flat on the floor. Rest your arm on a table so the cuff is at heart level.
2. Remain still and silent during the measurement.
3. Press the START/STOP button. The cuff will automatically inflate.
4. The device will detect your pulse and measure your blood pressure using the oscillometric method with fuzzy logic.
5. Once the measurement is complete, the cuff will deflate, and your systolic pressure, diastolic pressure, and pulse rate will be displayed.
6. Press the START/STOP button again to turn off the device, or it will automatically switch off after approximately one minute of inactivity.

4.2 Memory Function

The device stores previous measurements for tracking your blood pressure over time.

• To recall stored measurements, press the M (Memory) button when the device is off.
• Each press of the M button will cycle through the stored readings, displaying the most recent first.
• The number of stored readings may vary; refer to the display for the current memory index.

5. Maintenance and Care

Proper care ensures the longevity and accuracy of your blood pressure monitor.

• Cleaning: Clean the main unit and cuff with a soft, dry cloth. If necessary, use a cloth lightly dampened with water or a mild detergent. Do not use abrasive cleaners or immerse the device in water.
• Storage: Store the device in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity. Keep it in its original packaging or a protective case when not in use.
• Battery Replacement: Replace all batteries at the same time when the low battery indicator appears. Do not mix old and new batteries or different types of batteries.
• Cuff Care: The cuff is a delicate component. Avoid bending or creasing the air tube excessively. Do not wash the cuff in a washing machine.
