Applicable population: adults. Contraindications: None Location of use: hospital, home Operating principle By using air pressure to compress local arteries and change pressure, blood flow through blood vessels has a certain oscillation wave. Based on the changes in the oscillation wave, the detected pressure and fluctuation also change accordingly. Based on the accumulated experience of software algorithms, the diastolic pressure, systolic pressure, and pulse of the human body are obtained. 21 34 Don’t use the mobile phone near the product . Don’t dismantle or repair ,renovation the main body of the blood pressure or cuff. Use only 1.5V alkaline batteries with this device. Do not use other types of batteries. This may damage the unit. If battery fluid should get in your eyes, immediately rinse with plenty of clean water. Contact a physician immediately. If battery fluid should get in your skin or your clothes, immediately rinse with plenty of clean water. Don’t install the wrong battery positive and negative. When the Low Battery Indicator appears on the display screen turn the monitor off and remove all the batteries. Replace with four new batteries at the same time. Long time no using(more than 3 months) , please take out the batteries. Dispose of the battery, components and optional accessories according to applicable local regulations. Unlawful disposal may cause environmental Pollution. Don’t mix the new and old battery ,or different type of battery. Do not use the device for any purpose other than measuring blood pressure. Do not disassemble the monitor or arm cuff. Doing so may cause inaccurate readings. Do not use in a humid environment or a location where water may splash onto the device. Doing so may damage the : device. Caution: When DC5V powered via USB only used IEC 60601-1 approved adapter witch meets 2MOPP If other Cuff and dry batteries are used, it may result in inaccurate measurement values. If other adapters that do not comply with IEC 60601-1 are used, there may be a risk of electric shock. The minimum storage temperature between two uses and the time required to heat up to the int ended use is half an hour The maximum storage temperature between two uses cools down to half an hour before preparation for use The product isn’t int ended for self-use in public areas. This product may result in inaccurate measurement values under extreme temperature, humidity, and height conditions The arm strap used in this product has passed the biocompatibility test, but it is not ruled out that there may be an allergic risk when used by multiple people. If accidental sensitization occurs, please consult your doctor. Do not operate the device in a moving vehicle e.g. car, airplane, boat. Do not excessively crease the arm cuff.
