Thank you for purchasing this Arm Blood Pressure Monitor. The monitor can be used and store measurement results for two users. It uses the oscillometric method of blood pressure measurement. This means this monitor detects your blood movement through your brachial artery and converts the movements into a digital reading. The device can be used in homecare environment, and the patient is an intended operator, and all the functions can be safely used. 1.
3. Safety Precautions and Warnings • No maintenance or servicing the monitor when using. • The patient is an intended operator, and all the functions can be safely used. • Do not operate when charging. • Dispose of the monitor when its service life is reached. Follow local regulations regarding the disposal of such product. • When the performance changes (such as: inaccurate measurement or abnormal display), please stop using it immediately and contact the after-sales service personnel in time.
• DO NOT use this monitor on infants, toddlers, children or persons who cannot express themselves. • DO NOT adjust medication based on readings from this blood pressure monitor. Take medication as prescribed by your physician. ONLY a physician is qualified to diagnose and treat high blood pressure. • DO NOT use this monitor on an injured arm or an arm under medical treatment. • DO NOT apply the arm cuff on your arm while on an intravenous drip or blood transfusion.
• To help avoid strangulation, keep the air tube and type C cable away from infants, toddlers and children. • Stop using this monitor and consult with your physician if you experience skin irritation or discomfort. • Consult with your physician before using this monitor on an arm where intravascular access or therapy, or an arterio-venous (A-V) shunt, is present because of temporary interference to blood flow which could result in injury.
• DO NOT use this monitor in a moving vehicle such as in a car. • DO NOT drop or subject this monitor to strong shocks or vibrations. • DO NOT use this monitor in places with high or low humidity or high or low temperatures. • Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation.

7. Classification of BP (Blood Pressure) ACC/AHA 2017 Hypertension guidelines define categories of BP in adults as below. Categories of BP in Adults* BP Category Systolic BP Normal < 120 mmHg Diastolic BP < 80 mmHg Elevated 120 - 129 mmHg < 80 mmHg 130-139mmHg or 80-89mmHg or Hypertension Stage 1 Stage 2 ≥ 140 mmHg ≥ 90 mmHg * Individuals with Systolic BP and Diastolic BP in 2 categories should be designated to the higher BP category.

Please keep silent and relax. Keep the cuff at the heart level. ①If your blood pressure is in normal range： Thank you. Your blood pressure is: Systolic pressure xxx millimeter of mercury pillar. Diastolic pressure xx millimeter of mercury pillar.
Thank you. Wish you a good health. ②If your blood pressure is not in normal range： Measuring result is abnormal. Your blood pressure is high/low Could not measure your pulse at this time.
kPa mode mmHg mode 11.How to Take Proper Measurements (1) Preparation before measurement --Remove the clothing on the arm. --Always measure in the same arm (generally the left arm). --Remain still and keep quiet during measurement. --Relax as much as possible and do not talk during measurement. --Measure your blood pressure at about the same time every day. --Do not measure right after physical exercise or a bath. Rest for 20 to 30 minutes before taking the measurement.
(2) Applying the arm cuff 1) Connect the arm cuff to your monitor by inserting the air plug into the air jack securely. 2) Place your hand through the cuff loop. Pull the cuff until it reaches your upper left arm.
Note • The bottom edge of the arm cuff should be 0.79-1.18 inches (2 to 3 cm) above the inside elbow.

(2.7 kPa - 4.0 kPa) lower than that measured in hospitals. It is because people are nervous when measured in hospitals, while they tend to be in a stable mood when measured at home. It is important to understand the normal blood pressure when you are at home. 2) If the cuff is placed in a position above the heart, the measured blood pressure is low, so please measure in the correct posture. Q2.
might be increased due to the abdominal pressure or due to the arm position lower than the heart. → Please make measurement in correct posture. Q3. When will the measurement be better? Please make measurement in the morning after you get up to urinate or when your body and mood are in stable state. It is better to make measurement at the same time every day. Q4. Why the blood pressure value measured each time is different? 1) When systole each time, the blood pressure will change to some extent.
compressed, resulting that the finger tip blood does not flow smoothly, If you continue the measurement in case of extravasated blood, you cannot obtain the correct measured value. Loosen the arm band, raise your hand over the head, and grasp and stretch your left and right palms for 15 times repeatedly. Then the extravasated blood can be dissolved, and you can continue the blood pressure measurement. 2) Cuff position and twining method. The measured value varies with the cuff size.
