8. Tighten the cuff evenly around your arm by
pulling on the end — make sure the Фmarker
stays aligned with the center of your arm.
9. Wrap the end of the cuff over your arm to secure
it in place. Don’t make it too tight — allow a

Taking a Measurement
1. Rest for at least 5 minutes, and avoid exercise and
caffeine for at least 30 minutes before you take a reading.
Lay your arm on a table with your palm facing up. The cuff
should be at the same height as your heart. Sit up straight
and rest your feet at on the ground. Make sure the tube is
not kinked or pinched.
2. Press the START/STOP button on the device to turn it on.
3. Wait for the device to power on, and perform the
measurement while inating the cuff. Try not to speak
or move during this time.
4. When the measurement concludes, results are shown on
the display, and the cuff automatically deates.
5. Remove the cuff after it deates.
