How to Use
1．Batteries Installation
Press the indicator ▼ on the battery cover and slide the cover off in
the direction of the arrow
Insert 4 “AA” size batteries, align the polarities of the battery.
Note:
If the low battery indicator appears in the display, the batteries must be
replaced.This monitor can also be operated with USB charging
WARNING
Pls purchase AC adapter (USB port) with CE certification.

2. Unit (mmHg/ kPa) Display Setup and Memory Deletion.
In power off condition, press SET button for 3 seconds. Enter into
the setup interface, the content of setup will be displayed by flashing.
Press the SET button again, then it will enter into the switch of setup
content “memory deletion ->unit display->speaker function(option).”
Press MEM button to revise setup value.
Press ON/OFF button to store the setup content.
Note:
This monitor displays two units: mmHg/ kPa, the user manual takes
mmHg as an example to illustrate.The default unit is mmHg.

3．Cuff Connection
Insert the air tube plug into the socket by revolving it.
4．Fitting the Arm Cuff
Take off thick clothes, wear thin clothes or unclothe your upper arm
for measurement. Lay the cuff on the upper arm. Turn the palm of
your hand upward. Put one side of the cuff (with Velcro) through the
metal ring to form a cylinder.
03
Tighten the cuff by affixing the Velcro.
The cuff should be snug on your upper arm.
Make sure that the bottom of the cuff lies approximately 1 to 2 cm
above the elbow and the air tube lies on the inner of the arm. The
tube should be aligned with your middle finger after it has been
straightened.

Note:
Both of your arms can be measured, but there are about 10mmHg
differences between them. Each measurement should be made
with the same arm.
5. Adjust Your Sitting Posture
Sit on a chair with your feet flat on the floor. Put your arm on a table
with your hand upward, relax and keep the cuff parallel with your
heart.
The arm cuff should be at the
same level as your heart.
Sit upright with
your back straight.
Take off thick clothes, wear
thin clothes or bare your
upper arm for measurement
6．Taking a Measurement
(1). Press ON/OFF button to power on, The pump starts to inflate
the cuff.
04
ON
OFF

(2). After having reached the anticipated value of inflation, the
monitor starts to deflate automatically with a constant speed to detect
your blood pressure and pulse.
(3). When the measurement is completed, your
blood pressure and pulse rate will be displayed.
Example:
SYS: 128mmHg
DIA: 78mmHg
Pulse: 68/min
The result will be stored automatically. The storage series
number is “0”. The previous measurement serial number is
“1”, and so forth.
(4). To shut off the monitor, press ON/OFF buttom.
05

Note:
Once you feel uncomfortable with inflation or the inflation becomes
ceaseless, please loosen the cuff and pull out the air tube
immediately.
Don’t talk, move your arm or body during the measurement.
06
The monitor will be automatically shut off in 3 minutes without
operation. When the monitor can’t measure the value correctly, the
screen will display “E” icon.
Press ON/OFF button to shut off the monitor and wait for 4 to 5
minutes to start a new test. At the same time, follow the following
suggestions during the measurement to avoid “E” icon display again.
1. Keep quiet and correct posture.
2. Fit the cuff correctly.
3. Connect the air tube correctly.
4. Avoid the electromagnetic interference.
7. Reading Memory
Press MEM button to check memory.
Press MEM and SET button to read more stored memories.
Note:
The monitor can memorize 60 data. The monitor will delete the earliest
data automatically when the number of data is beyond 60.

8. Manual and Auto Inflation
● In most of cases, choose auto inflation. If your systolic pressure is
more than 220mmHg, choose manual inflation.
9. Advice for Self-measurement
● Avoid eating, smoking, drinking alcohol, exercising, bathing as
well as forms of exertion activities before measurement.
● Keep quiet and relax for measurement.
● Keep correct posture during the measurement.
●Take measurement on the same arm (normally left) and posture
regularly at the same time of the day.
● Do not take the measurement in an extreme temperature.
The digital blood pressure monitor could pre-detect your blood
pressure during the process of inflation, and set specific inflation
value for your measurement. The measuring time is shortened
and every user could enjoy quick and comfortable measurement.
Common Sense of Blood Pressure
1. About Blood Pressure
● In the process of inflation, press MEM button for manual inflation.
The preset value will be 260mmHg.
The preset value will add 20mmHg by each touch.
07
Blood is carried from the heart to all parts of your body through
vessels called arteries. Blood pressure is the force of the blood
pushing against the walls of the arteries.

Each time the heart beats, it pumps out blood into the arteries.
Blood pressure is at its highest when the heart pumps or ejects blood.
This is called Systolic Blood Pressure.
Blood pressure is at its lowest when the heart rests ( in- between beats).
This is called Diastolic Blood Pressure.
The blood pressure is constantly changing. The different cuff fitting
and measurement posture can cause the blood pressure to change.
You should take the measurement at the same time with the same
arm and posture everyday.

3. Life Guide for Hypertension Patients
※High blood pressure (Hypertension);
A blood pressure of 140/90 or higher is considered high blood
pressure. High blood pressure (HBP) is a serious condition that can
lead to coronary heart disease, heart failure, stroke, kidney failure,
and other health problems. Blood pressure tends to rise with age.
Following a healthy lifestyle helps some people delay or prevent this
rise in blood pressure. The following measures can be regarded as a
life guide for hypertension patients:
1) Consult your doctor about your blood pressure in daily life.
2) Maintain a normal weight.
3) Avoid excessive consumption of common salt. Avoid high cholesterol
foods and fatty foods. Eat more fruits, vegetables and high-fiber foods.
4) Avoid smoking, alcohol and reviver.
5) Moderated exercise.
6) relax and reduce stress. Stress can increase the blood pressure
suddenly. Relax and reduce stress is a good habit for your health.
