Measuring Blood
Pressure
When to Take Blood Pressure
• The best times to take your blood pressure are
within 1 hour of waking in the morning or 1 hour
before bedtime.
• When measuring in the morning, measure after
urinating and before eating breakfast.
• Always measure your blood pressure before
taking blood pressure medication.
• If you need to measure your blood pressure at
another time of day, make sure you are calm and
stable before measuring.
• Measure your blood pressure at the same time
every day. Blood pressure changes during the
course of the day by as much as 20–40 mmHg.
• Follow any directions given by your physician
regarding how and when to measure your blood
pressure.
Data Transmission
• To enable the data transmission function, this

reasonably close, within 3–32 ft / 1–10 m.
• Ensure no obstacles are between your
monitor and your phone to allow for quality
connection and to lower the RF output range.
• To avoid interference, other electronic devices
(particularly those with wireless transmission)
should be kept at least 3 ft / 1 m away from the
monitor.
