For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated 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.

8．About Blood Pressure
8.1 What is Blood Pressure?
and is one of the principal vital signs.
Two pressures are measured for a blood pressure reading:
• Systolic blood pressure is a measure of blood pressure while the heart is beating.
• Diastolic pressure is a measure of blood pressure while the heart is relaxed.
• Systolic blood pressure is a measure of blood pressure while the heart is beating.
• Diastolic pressure is a measure of blood pressure while the heart is relaxed.
8.2 What is High Blood Pressure?
High blood pressure, also known as HBP or hypertension, is a widely misunderstood medical
condition. Some people think that those with hypertension are tense, nervous or hyperactive, but
hypertension has nothing to do with personality traits. The truth is, you can be a calm, relaxed
person and still have HBP. Let's look at the facts about blood pressure so you can better
understand how your body works and why it is smart to start protecting yourself now, no matter
what your blood pressure numbers are.
By keeping your blood pressure in the healthy range, you are:
• Reducing your risk of your vascular walls becoming overstretched and injured
• Reducing your risk of your heart having to pump harder to compensate for blockages
• Protecting your entire body so that your tissue receives regular supplies of blood that is rich in
• Reducing your risk of your vascular walls becoming overstretched and injured
• Reducing your risk of your heart having to pump harder to compensate for blockages
• Protecting your entire body so that your tissue receives regular supplies of blood that is rich in
the oxygen it needs
According to World Health organization standard, the blood pressure level classification and
definition as following:
Category
Systolic（mmHg）
Diastolic（mmHg）
Desirable
<120 and
<80
