IMPORTANT INFORMATION
NORMAL BLOOD PRESSURE FLUCTUATION
All physical activity, excitement, stress, eating, drinking, smoking, body posture and many
other activities or factors (including taking a blood pressure measurement) will influence blood
pressure value. Because of this, it is mostly unusual to obtain identical multiple blood
pressure readings.
Blood pressure fluctuates continually ----- day and night. The highest value usually appears in
the daytime and lowest one usually at midnight. Typically, the value begins to increase at
around 3:00AM, and reaches to highest level in the daytime while most people are awake and
active.
Considering the above information, it is recommended that you measure your blood pressure
at approximately the same time each day.
Too frequent measurements may cause injury due to blood flow interference, please always
relax a minimum of 1 to 1.5 minutes between measurements to allow the blood circulation in
your arm to recover. It is rare that you obtain identical blood pressure readings each time.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be determined using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
