(TMB-1776-B). The monitor features blood pressure measurement, pulse rate measurement and the result storage. The design provides you with two years of reliable service. Readings taken by the TMB-1776-B are equivalent to those obtained by a trained observer using the cuff and stethoscope auscultation method. This manual contains important safety and care information, and provides step by step instructions for using the product. Features:

80mm58.5mm Digital LCD display Maximum 60 records 3rd technonoly: Measuring during inflation Indications for Use The Transtek Blood Pressure Monitor is digital monitors intended for use in measuring blood pressure and heartbeat rate with arm circumference ranging from 22cm to 42cm(about 8-16). It is intended for adult indoor use only. Contraindications 1.The device should not be used by any person who may be suspected of,or is pregnant . 2.The device is not suitable for use on patients with implanted,electrical devices, such as cardiac pacemakers, defibrillators. Measurement Principle This product uses the Oscillometric Measuring method to detect blood pressure. Before every measurement, the unit establishes a zero pressure equivalent to the atmopheric pressure. Then it starts inflating the arm cuff, meanwhile, the unit detects pressure oscillations generated by beat-to-beat pulsatile, which is used to determine the systolic and diastolic pressure, and also pulse rate.

(1)Turn on Bluetooth and the app. Make sure both are ON when pair-up is proceeding.

(2)When the monitor is OFF, press and hold the MEM button to start pair-up. The below picture will be shown on the LCD alternatively,indicating pair-up is proceeding. 2~3cm 1. 2. 3. Remove all jewelry, such as watches and bracelets from your left arm. Note: If your doctor has diagnosed you with poor circulation in your left arm, use your right arm. Roll or push up your sleeve to expose the skin. Make sure your sleeve is not too tight. Hold your arm with your palm facing up and tie the cuff on your upper arm, then position the tube off-center toward the inner side of arm in line with the little finger. Or position the artery mark over the main artery (on the inside of your arm). Note: Locate the main artery by pressing with 2 fingers approximately 2 cm above the bend of your elbow on the inside of your left arm. Identify where the pulse can be felt the strongest. This is your main artery. 4. The cuff should be snug but not too tight. You should be able to insert one finger between the cuff and your arm. 5. 6. Sit comfortably with your tested arm resting on a flat surface. Place your elbow on a table so that the cuff is at the same level as your heart. Turn your palm upwards. Sit upright in a chair, and take 5-6 deep breaths. Helpful tips for Patients, especially for Patients with Hypertension:

Rest for 5 minutes before first measuring. Wait at least 3 minutes between measurements. This allows your blood circulation to recover. Take the measurement in a silent room. The patient must relax as much as possible and do not move and talk during the measurement procedure. The cuff should maintain at the same level as the right atrium of the heart. Please sit comfortably. Do not cross your legs and keep your feet flat on the ground. Keep your back against the backrest of the chair. For a meaningful comparison, try to measure under similar conditions. For example, take daily measurements at approximately the same time, on the same arm, or as directed by a physician.

(3)Then connect with your smartphone on the app to continute the pair-up. If SUCCEED, the below picture will be shown on the LCD. If FAIL, the below picture will be shown on the LCD.

(4)The monitor will shut off after Pair-up process is complete.

Within 1 hour after dinner or drinking Immediate measurement after tea, coffee, smoking Within 20 minutes after taking a bath When talking or moving your fingers In a very cold environment When you want to discharge urine 19 INFORMATION FOR USER ABOUT BLOOD PRESSURE Maintenance instructions below. In order to get the best performance, please follow the Put in a dry place and avoid the sunshine Avoid touching water, clean it with a dry cloth in case. Avoid intense shaking and collisions Avoid dusty and unstable temperature environment Using wet cloths to remove dirt Do not attempt to clean the reusable cuff with water and never immerse the cuff in water. 20 What are systolic pressure and diastolic pressure?

When ventricles contract and pump blood out of the heart, the blood pressure reaches its maximum value in the cycle, which is called systolic pressure. When the ventricles relax, the blood pressure reaches its minimum value in the cycle, which is called diastolic pressure. Systolic blood discharging artery Diastolic blood entering vein press relax What is the standard blood pressure classification?

The chart on the right is the standard blood pressure classifi-

cation published by American Heart Association (AHA). This chart reflects blood pressure categories defined by American Heart Association. Blood Pressure Category Systolic mmHg (upper#) Diastolic mmHg (lower#) Normal Elevated less than 120 and less than 80 120-129 and less than 80 High Blood Pressure

(Hypertension) Stage 1 High Blood Pressure

(Hypertension) Stage 2 130-139 80-89 or or 140 or higher 90 or higher Hypertensive Crisis

(Consult your doctor immediately) Higher than 180 and/or Higher than 120 CAUTION Please consult a physician if your measuring result falls outside the range. Please note that only a physician can tell whether your blood pressure value has reached a dangerous point. Irregular Heartbeat Detector An irregular heartbeat is detected when a heartbeat rhythm varies while the device is measuring systolic pressure and diastolic pressure. During each measurement, blood pressure monitor will keep a record of all the pulse intervals and calculate the average value of them. If there are two or more pulse intervals , the difference between each interval and the average is more than the average value of 25% , or there are four or more pulse intervals ,the difference between each interval and the average is more than the average value of 15%, then the irregular heartbeat symbol will appear on the display with the measurement result. CAUTION The appearance of the IHB icon indicates that a pulse irregularity consistent with an irregular heart-beat was detected during measurement. Usually this is NOT a cause for concern. However, if the symbol appears often, we recommend you seek medical advice. Please note that the device does not replace a cardiac examination, but serves to detect pulse irregularities at an early stage. 21 ABOUT BLOOD PRESSURE TROUBLE SHOOTING Why does my blood pressure fluctuate throughout the day?

1. Individual blood pressure varies multiple times everyday. It is also affected by the way you tie your cuff and your measurement position, so please take the measurement under the same conditions. 2.If the person takes medicine, the pressure will vary more. 3.Wait at least 3 minutes for another measurement. Why do I get a different blood pressure at home compared to the hospital?

The blood pressure is different even throughout the day due to weather, emotion, exercise etc, Also, there is the white coat effect, which means blood pressure usually increases in clinical settings. What you need to pay attention to when you measure your blood pressure at home:

If the cuff is tied properly. If the cuff is too tight or too loose. If the cuff is tied on the upper arm. If you feel anxious. Taking 2-3 deep breaths before beginning will be better for measuring. Advice: Relax yourself for 4-5 minutes until you calm down. Is the result the same if measuring on the right arm?

It is ok for both arms, but there will be some different results for different people. We suggest you measure the same arm every time. 22 This section includes a list of error messages and frequently asked questions for problems you may encounter with your blood pressure monitor. If the products not operating as you think it should, check here before arranging for servicing. PROBLEM SYMPTOM CHECK THIS REMEDY No power Display will not light up.
