Foreword

Hypertension (High Blood Pressure) is one of the three major
diseases that are of great danger to mankind. It is known as
the INVISIBLE KILLER. The higher the blood pressure, the
higher the incidence of the heart disease or incidental
cerebrovascular (apoplexy) disease. Therefore, early
diagnosis as well as prompt treatment of hypertension is of
great significance.

Attention :
Hypertension could cause the narrow of arterial blood vessels
or the obstacle in twig blood circulation, which shall cause the
difference of blood pressure values between wrist blood
pressure and upper arm blood pressure. Even for healthy
persons, the difference between wrist and arm blood pressure
values might be about 20mmHg (2.5Kpa). So, please do not
judge your blood pressure by yourself and consult your
doctors.

- 2 of 35 -

Blood pressure values change is the same by measuring wrist
or upper arm. Therefore, one can monitor the change of his
blood pressure values by measuring wrist blood pressure.
Blood pressure changes throughout the day and even without
feeling, body blood pressure will change ranging from
30mmHg-50mmHg according to body tension or relaxation
state.

About Blood Pressure

Blood pressure is the pressure exerted on the arterial walls
when blood flows through the arteries. The pressure exerted
when the heart contracts and sends out blood is called systolic
(highest) pressure. The pressure exerted when the heart dilates
and blood flows into the heart is called diastolic (lowest)
pressure. Blood pressure is a physiological index subject to
wide fluctuations, which might be influenced by talk, movement,
posture, mood, etc., and possesses the property of periodical
change throughout the day. And therefore, using different body

- 3 of 35 -

parts for measurement (such as wrist or upper arm), different
blood vessel wall thickness as well as different measurement
time will probably generate different measuring results.

SF822B

It uses the Oscillometric method of measurement and
automatically pressurizes and measures blood pressure and
is capable of displaying minor changes of the blood pressure
measured. It also has saving function and can save pulse,
blood pressure values and measured time.

correct readings.

- 14 of 35 -

Do not speak and do not touch the monitor when measuring is
taking place.

Your blood pressure readings displayed may be higher
than normal under the following circumstances:

a) if you measure immediately after drinking alcohol or

smoking, having meals or after a strenuous physical
workout

b) if you are stressed out, have mood swings or have had

inadequate sleep

c) if you feel like going to the lavatory

Measuring Method

1. Press the On/Off button. All
characters and symbols will flash
on the screen, confirming normal
display.

- 15 of 35 -

2. After about one second , the
air relief symbol Ð begins to
flash, indicating the Blood
Pressure Monitor is deflating the
residual air in the Wrist Holder.

3. Upon the completion of air
deflating, you will hear the buzzer
beep and meanwhile the air relief symbol Ð will disappear.
This completes the initialization process and the unit is ready
for measurement.
Indicator ♥ will appear, and the digit
0 (zero) will show up on the Display.
The system is set to measure mode
by default and the Mode Indicator
MEA is displayed.

4. The unit is in command waiting
status at this moment and other functions can be navigated by
pressing the MODE key. In the measurement mode, in case

- 16 of 35 -

setting of the upper limit of pressurization is not activated by
the user for 3 seconds, the unit will automatically commence
to pressurize. Pressurizing symbol Ï will be displayed and the
air pump will automatically inflate and pressurize the Wrist
Holder and the system enters the measurement mode. The
MODE key and SET key will not respond to operation before
the completion of measurement.

5. Gradually ascending

pressure value can be seen on
the Display Window and you
can feel the Wrist Holder
tightening your wrist gradually.
The air pump will stop
automatically as the pressure reaches the set value, and the
pressurization symbol Ï will disappear, indicating the end of
pressurization. When air pressure detected by the system is
inadequate, the air pump will be started again to continue to
pressurize to reach a higher air pressure level. The air

- 17 of 35 -

pressure levels set as follows, in
mmHg unit:
180, 240 and 290, totaling 3 grades.

6. Upon the completion of
pressurization, the air pressure inside the Wrist Holder will
decrease automatically. A buzzer
accompanied by flashing of the
symbol ♥ on the Display Window
indicates the beginning of the
measurement of your blood pressure
and pulse.
Please wait patiently for the readings.

7. Upon the completion of
measurement, the air relief
symbol Ð will flash, and the residual air inside the Wrist
Holder will be discharged quickly. The buzzer will beep when

- 18 of 35 -

the air pressure inside the Wrist Holder
descends below 5mmHg, and
meanwhile, the symbol ♥ will
appear on the Display Window. And
then, your blood pressure values as
well as pulse will show upon the
screen alternately (blood pressure and
pulse displayed about 3.5 seconds and
2 seconds respectively).

8. Upon the completion of your measurement after you turn

the machine on, the system will not pressurize automatically
in case MEA still displays. Next operation is available by
pressing the SET key with one touch.

9. Just press On/Off button to turn the machine off.

Blood Pressure Commonsense

Blood pressure fluctuates all the time and possesses the
property of periodical change within one day.

- 19 of 35 -

Fluctuation Within A Day

- 20 of 35 -

The basic blood pressure is your blood pressure taken when
you are at your calmest, both mentally and physically. Since it
is the basic index used when assessing the current state of
your health, due importance should be accorded.
This basic blood pressure should be measured ideally under
the following conditions:

 30 minutes to one hour after waking up (before breakfast)
 At room temperature of 15 degrees to 25 degrees Celsius

(60 F to 80 F)

 After resting your body for more than 30 minutes
 After using the lavatory
 When you feel physically and mentally calm

Please try to keep the correct posture while measuring.

Do not be too anxious or too affirmative about your temporary
blood pressure readings. Please record the variations of your
daily blood pressure, and then consult with your doctor. The
measuring results of continuous examinations might be

- 21 of 35 -

dramatically different, and it is caused by changed volume of
blood flow resulted from deformed blood vessels upon
pressure (particularly common for the old because of the poor
flexibility of their blood vessel, their high blood viscosity as
well as low recovery speed).

Generally, your blood pressure value taken in a hospital is
higher 20mmHg-30mmHg than that taken at home. This is
caused by a sudden rise of your blood pressure on account of
your nervousness resulting from your body’s alert reactions to
movement, crowd, surroundings as well as the presence of
medical staff.
Your pulse, just as your blood pressure value, will also change
along with the difference of your body condition as well as
physical movement.

Save, Inquiry and Clear

The SAVE function can record the high blood pressure
(systolic) value, low blood pressure (diastolic) value, pulse
and measured time upon the completion of measurement by
pressing MODE key to select SAVE function followed by
pressing SET key to confirm SAVE function. The system will
not respond to SAVE function other than in the above situation
even if the MODE key is pressed down to select the SAVE
function followed by pressing SET key to confirm. On the
contrary, the system will automatically transfer to the next
operation mode---QUE mode.

After finishing measurement, press Mode key to choose save
function. With the display of indication SAVE, it will appear
NO.1, which indicates to save the first measurements. You

can continue to press MODE key to save the second (NO.2)
or the third (NO.3) measurement. It can save measured pulse,
systolic, diastolic values and
measured time only after pressing
set key again. The system
automatically chooses saving order
and can save 30 measurements for
each one at most.

Upon the number of sets saved exceeding 30, the system will
erase the oldest values and keep the latest values. Saving
order keeps unchanged.

After switching the unit on, the
symbols 0, ♥ and the measuring mode
indicating SAVE will display on the

screen. The system is in command waiting status and press
MODE key to select query measurements function.
When the mode indication QUE
displays, NO.1 will appear on the
screen and indicate to query the first
person’s measurements. You can
choose to query the second or the third
person’s measurements by pressing
MODE key continuously. Press SET
key again to confirm.
A set of saved measurement values
numbered 1 will appear on the screen.
(The first screen display is pulse
symbol P, saving NO., pulse value and
measuring time. The second screen
display is systolic and diastolic pressure values. ) Upon
pressing SET key once again, another set of saved values
numbered 2 will appear on the screen and so on. After the last

- 25 of 35 -

numbered 30 set of saved values has thus been displayed,
pressing SET key once again, the system will display saved
values numbered 1 again. Further pressing of SET key will
again display the values at number 1 and so on cyclically.

When the system is in command waiting status, press MODE
key to select clear function. When the mode indication CLR
displays in the LCD, CLr no.1
displays and CLr is flashing,
which indicates to clear the first
person’s measurements. You can
choose to clear the second (NO.2)
or the third (NO.3) person’s
measurements by pressing MODE key continuously. Press
SET key again to confirm and the system will clear all saved
