5. Operation

5.1. Applying the Intelli Wrap Cuff

The Intelli Wrap Cuff is designed for easy and accurate placement. It can be applied to virtually any position around the upper arm.

1. Sit in a chair with your feet flat on the floor. Rest your arm on a table so the cuff is at heart level.
2. Slide your arm through the cuff loop. The air tube should run down the inside of your arm.
3. Position the cuff so the bottom edge is 1-2 cm above your elbow.
4. Secure the cuff firmly using the fabric fastener. Ensure it is snug but not too tight. The monitor features a cuff wrap guide to confirm correct placement.

5.2. Taking a Measurement

1. Select User 1 or User 2 using the designated switch or button, if available. The M400 supports memory for two users.
2. Press the START/STOP button. The cuff will begin to inflate automatically using Intellisense technology, which ensures comfortable inflation without over-pressurization.
3. Remain still and silent during the measurement.
4. Once the measurement is complete, your systolic pressure (SYS), diastolic pressure (DIA), and pulse rate will be displayed on the screen.
5. The monitor will also indicate if an irregular heartbeat was detected or if your blood pressure is excessively high (hypertension indicator).
6. Press the START/STOP button again to turn off the monitor. If you do not turn it off, it will automatically shut down after a few minutes.
