Do not touch the blood pressure monitor while taking measurements.
Do not talk while taking measurements.
IMPORTANT:
•Measure your blood pressure at the same time and under the same conditions every day if possible. The ideal time to measure your blood pressure is in the morning immediately after waking up, while you are still relatively calm. If this is not possible, try to take your blood pressure prior to breakfast, before you become active.
•Relax and take measurements in a comfortable position.
•Rest for at least 5 minutes before taking a measurement.
•Keep still and do not speak during measurement. Blood pressure can fluctuate with the slightest change, such as tensing your muscles or changing your posture.
Do not use close to cellular phones or other devices which emit electromagnetic waves. Doing so may result in malfunction.
