Troubleshooting:
1.If there is no display on the screen when the on/off button is pressed, please confirm if the battery is new.
2. If it is impossible to measure or the reading is too high, please re measure with the correct posture
3.If the measured blood pressure is abnormally high or low, please wear a wristband correctly, relax, and then re measure. During the measurement process, please remain quiet and do not speak.
4. If pressing the ON/OFF button，the pressure is not applied but the reading still appears, please turn off the sphygmomanometer first and then turn on the measurement.
5.If the blood pressure measured each time is different and the reading is too high or too low, please relax first. Because in a tense state, the results of each measurement will constantly change, it is recommended to take a deep breath and calm down before taking the measurement.
