User manual IBP J401

[. . . ] The measurement of your blood pressure is based on this baseline pressure. After the cuff inflates to block your blood in the artery, the deflation process starts. During the deflation of the wrist cuff, J401 is detecting the pressure oscillations generated by the beat-to-beat pulsatile. Any muscle movement during this period of time will cause measurement error. [. . . ] Applying the cuff Apply cuff to left wrist with palm facing up (1). Make sure the edge of the cuff is about 1 cm from the palm (2). Correct Measuring Posture Place your elbow on the table so that the cuff is at the same level as your heart. Measurement Procedures Press the "User-Switching" key to select a memory zone, and press the " " key to start measurement in the chosen memory zone. After checking the display with all digits lighting up, the monitor will automatically inflate. When completed, the systolic pressure, diastolic pressure and pulse rate will be shown simultaneously on the same LCD screen. The values are automatically stored in the pre-designated memory zone. Press the "User-Switching key" to select a memory zone, and press the "M" key to switch from memory to memory with sequence numbers. Clear Values from Memory Press the "User-Switching key" to select a memory zone, then press and hold the "M" key for approximately 5 seconds to clear the data in the pre-designated memory zone. The data may be erased if any of the batteries is removed. (Suggest the users to first record the data on the blood pressure log before replacing or moving away the batteries. Then press the " " and " " in turn to adjust the date, hour, minute and confirm the entry. Avoid dropping or strongly shocking the main unit, and protect it from dust. Remove the batteries when the unit is not used for a long time. The unit should not be operated by children so to avoid hazardous situations. You should not use any tool to open the device nor should you attempt to adjust anything inside the device. If you have any problems, please contact the store or the doctor from whom you purchased J401 or please contact Rossmax International Ltd. For users diagnosed with common arrhythmia (atrial or ventricular premature beats or atrial fibrillation), diabetes, poor circulation of blood, kidney problems, or for users suffered from stroke, or for unconscious users, the device may have difficulty in determining the proper blood pressure. Clean the blood pressure monitor body and the cuff carefully with a slightly damp, soft cloth. Do not wash the cuff or use chemical cleaner on it. [. . . ] If error keeps occurring, return the device to the local distributor or service center.
