1. Before Using the Device
1.1 Indications For Use
This wrist blood pressure monitor is intended to be used to measure blood pressure and
pulse rate from the wrist by using the oscillometric method, at home or in medical centers.
This device is intended for use on adults only and is not for use on groups such as
neonatal babies, children, pregnant women, or pre-eclamptic patients.
1.2 Important Safety Information and Precautions
WARNING
•Contact your physician if you suspect you have a medical issue.
• Not for use by children, pregnant women, or pre-eclamptic patients.
• If you suffer from arrhythmia, diabetes, blood circulation problems, or apoplexy,
only use the device under a physician’s care.
• Prolonged over-inflation of the monitor will result in harmful injury to the patient.
• Do not use the device over a wound, as this can cause further injury.
• Too frequent measurements can cause injury due to blood flow interference.
• Users should not attempt to modify the device in any way.
• Store device in a cool, dry place. Do not subject the device to extreme
temperatures, humidity, or sunlight. The device might not meet performance
specifications if stored or used outside the ranges specified in the
“Specifications” section.
• Do not immerse the device in water or clean with cleaning products, alcohol, or
solvents. Carefully follow cleaning instructions provided.
•If the equipment is not available for three months or more, please use the
appropriate power adapter for recharging.
• Ensure that the device is used in the environment specified in the EMC
declaration in this IM, otherwise, may result in improper operation.
• Use of this device adjacent to or stacked with other device should be avoided
because it could result in improper operation.
• This electrical medical equipment requires specific precautions regarding
electromagnetic compatibility. It must be installed and used according to the

1.3 About Blood Pressure
BLOOD PRESSURE INDICATOR CHART
(World Health Organization (WHO) Blood Pressure Indicator)
* Consult Your Physician
When systolic and diastolic pressure falls into different categories, the higher pressure
determines color code.
Blood pressure measurements determined with this device are equivalent to those
obtained by a trained observer using the cuff/ stethoscope auscultatory method, within
the limits prescribed by European Society of Hypertension International Protocol revision
2010 for the validation of blood pressure measuring devices in adults.
An irregular heartbeat rhythm is defined as a rhythm that is more than 25% slower or 25%
faster from the average rhythm detected while the device is measuring the systolic blood
pressure and the diastolic blood pressure. When the device detects an irregular rhythm
two or more times during the measurement, the Irregular Heartbeat Symbol will be
displayed with the measurement values.

3. Instruction For Use
3.1 Before Taking a Measurement
• For most accurate results, measurements should be taken in the same circumstances and at
the same time every day.
• The unit can be applied to either wrist, but preferably the left. Use the same wrist for each
measurement.
• Any blood pressure recording can be affected by the position and physiological condition of
the subject, as well as other factors such as background noise, stress, talking and body
movement etc.
• Avoid taking measurements while under stress.
• Do not eat, drink alcohol, smoke, exercise, or bathe 30 minutes before using the unit, as
these activities may change blood pressure.
• For an accurate indication of true blood pressure, take and record several measurements
over a period of time.
• If consecutive measurements are desired, allow two minutes between uses to allow blood to
flow through the arm normally.
• This device is used to monitor blood pressure. However, it cannot treat or prevent high blood
pressure. If you suffer from high blood pressure, consult your doctor.
3.2 Take a Measurement
1. Ensure that the device should be used on bare
skin. Remove wristwatches or other jewelry. If
necessary, loosely roll up your sleeve to expose
wrist.
2. With screen aligned to the midline of the back
of the hand, wrap and fasten the watchband with
cuff around your wrist properly, not too tightly or
too loose.

3. •Comfortably seated
• Legs uncrossed
• Feet flat on the floor
• Back and arm supported,
• Keep the device at the same level as your heart.
• Relax as much as possible and not talk during the measurement.
4. While sitting upright in a chair with your feet flat on the floor, press “START ". Symbols
“”on screen will increase and cuff will begin to inflate. Do not move, activate arm
muscles, or talk during measurement.
5. Measurement can be stopped at any time by pressing “STOP".
6. When the unit senses a pulse, a heart symbol will flash on screen.
7. When measurement is complete, the cuff deflates automatically and the systolic,
diastolic, and pulse rate will display on screen.
8. Turn off the device by pressing “STOP".
4. Cleaning and Maintenance
• For regular maintenance, the device only needs to be wiped gently with a soft, dry cloth
while it is not being used. Never immerse the device or any components in water.
• Do not carry out repairs of any kind yourself. If a defect occurs, please contact your local
