Q & A
Q Why are the blood pressure values measured at home different
from those measured at the doctor’s office?
A Blood pressure varies in a 4-hour period.
In addition, it can vary greatly depending on the weather, your
mental state, amount of exercise, etc.
In particular, there is the phenomenon of “White uniform
hypertension” at doctor’s offices, where the blood pressure
measured in a doctor’s office is higher because of stress or anxiety.
In addition, if the blood pressure measured at home is
sometimes higher and sometimes lower than the blood
pressure measured at the doctor’s office, the following can be
considered. Please pay attention to these points when taking
measurements.
1 Measuring posture was poor.
Did you take measurements while leaning forward with your body
at an angle?
 Measurements were not taken at the upper arm.
Please take measurements with your elbow in the arm support of
the main unit. (See pages 15–17.)
3 Were you anxious or upset during measurements?
Before taking measurements, take  or 3 deep breaths and relax,
so that your blood pressure stabilizes.
Q Why do the main unit and the wireless display operate together
even when they are separated?
A The main unit and the wireless display communicate using infrared
rays. Infrared rays are transmitted from the transmitter on the side
panel of the main unit, and reflected on your body and then received
on the bottom of the front panel of the wireless display.
Q The mark does not light when an arm is moved.
A The mark is a function to notify you that your arm is bent or to
indicate extra loads on the pressure cuff.
Therefore, it may not indicate motion (bending an arm slightly, etc.).
If you are concerned about the result, retry the measurement.
