Device Overview On the upper surface of the recorder, you will find an OLED display, START/STOP switch, and EVENT switch.
The OLED display indicates the state of settings and the measurement value of ABPM. The START/STOP switch allows you to measure the blood pressure manually anytime other than the pre-set measuring time during ABPM.
The EVENT switch has functions to shift the mode of ABPM. The air socket to connect the cuff is also on the upper surface.

Check if the cuff size fits properly by measuring the mid-upper arm circumference or attaching the cuff. Wearing a thin shirt under the cuff does not influence the accuracy of measurement.
Attach the cuff so that the artery position mark is over the brachial artery of the patient. You can check the cuff size with the range mark on the cuff. Wrap the cuff so that the ring is within the range. If it is out of the range, please choose a smaller or larger cuff. The cuff should be attached so that the lower edge of the cuff is approximately 1 cm above the inside of the elbow.
