5. Setup

5.1. Battery Installation

1. Open the battery compartment cover on the bottom of the monitor.
2. Insert the 4 AAA batteries according to the polarity indicators (+ and -) inside the compartment.
3. Close the battery compartment cover securely.

5.2. Cuff Connection

1. Locate the air tube connector on the side of the monitor.
2. Firmly insert the air tube plug from the cuff into the connector port until it clicks into place.
3. Ensure the connection is secure to prevent air leakage during measurement.

6. Operating Instructions

6.1. Preparing for Measurement

• Avoid eating, drinking alcohol, smoking, exercising, and bathing for 30 minutes before measurement.
• Rest for at least 5-10 minutes before taking a measurement.
• Sit in a comfortable position with your back supported and feet flat on the floor. Do not cross your legs.
• Place your arm on a flat surface so the cuff is at heart level.
• Remove tight-fitting clothing from your upper arm.

6.2. Applying the Arm Cuff

1. Unroll the cuff and pass the end through the metal ring to form a loop. The smooth cloth surface should be on the inside of the loop.
2. Slide your left arm through the cuff loop. The air tube should run down the inside of your arm.
3. Position the cuff so the bottom edge is approximately 2-3 cm (0.8-1.2 inches) above your elbow joint. The artery mark on the cuff should align with your brachial artery (on the inside of your arm).
4. Tighten the cuff around your arm using the Velcro closure. Ensure it is snug but not too tight; you should be able to insert two fingertips underneath the cuff.

6.3. Taking a Measurement

1. Press the "START/STOP" button. The cuff will automatically inflate, and the measurement will begin.
2. Remain still and silent during the measurement. Do not talk or move your arm.
3. Once the measurement is complete, the cuff will deflate, and your systolic pressure, diastolic pressure, and pulse rate will be displayed on the screen.
4. If the voice broadcast function is enabled, the results will be announced.
5. The measurement will automatically be stored in the selected user's memory.
6. Press "START/STOP" again to turn off the device, or it will automatically power off after a period of inactivity.

6.4. Switching User Modes

The device supports two users (User 1 and User 2), each with independent memory storage.

1. Before taking a measurement, press the "SET" button to toggle between User 1 and User 2. The active user icon will be displayed on the screen.
2. All subsequent measurements will be stored under the selected user profile.

6.5. Recalling Memory Records

1. With the device off, press the "MEM" button to enter memory recall mode.
2. Repeatedly press the "MEM" button to cycle through previous measurements for the currently selected user.
3. To view the other user's records, first switch the user mode using the "SET" button, then enter memory recall.

7. Understanding Your Results

The display shows three main values:

• 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.

7.1. Irregular Heartbeat Detection (IHB)

If the device detects an irregular heartbeat during measurement, an IHB symbol (often a heart icon with wavy lines) will appear on the display. This indicates that a pulse rhythm inconsistent with a normal heartbeat was detected. If this symbol appears frequently, consult your physician.

8. Maintenance and Care

• Clean the monitor and cuff with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
• Store the device in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity.
• Remove batteries if the device will not be used for an extended period to prevent leakage.
• Do not attempt to disassemble or repair the device yourself. Contact customer support for assistance.
