MEDICAL DISCLAIMER
This manual and product are not meant to be a substitute for advice provided by your doctor or other medical professional. You are not to use the information contained herein, or this product for diagnosing or treating a health problem or prescribing any medication. If you have or suspect that you have a medical problem, promptly consult your healthcare provider.
Blood Pressure Monitor Intended Use:
Measures human's Systolic blood pressure, Diastolic blood pressure and heart rate on wrist by oscillometric measurement method.
The product is recommended for use by people over the age of 18 and is for home use and not clinical use.

1. What is blood pressure ?
Blood pressure is a measurement of the force of blood Àowing against the walls of the arteries. Arterial blood pressure is constantly changing during the course of the cardiac cycle. The highest pressure in the cycle is called the systolic blood pressure, the lowest is the diastolic blood pressure. Both pressure readings, the systolic and the diastolic are necessary to enable a physician to evaluate the status of a patient's blood pressure. Many factors such as physical activity, anxiety or the time of day, can inÀuence your blood pressure. Blood pressure is typically low in the morning and increases from the afternoon to the evening. It is lower in the summer and higher in the winter.
2. Why is it useful to measure blood pressure
at home ?
Having one's blood pressure measured by a doctor in a hospital or a clinic, and a group health checks, tend to stimulate nervousness in the subject and may even create high blood pressure. Also varies blood pressure in accordance with a variety of conditions and so judgment is not possible on the basis of a single measurement.
The blood pressure measured ¿rst thing in the morning after getting up, before taking any food and with the subject still, is known as the fundamental blood pressure. In practice it is rather dif¿cult to record the fundamental blood pressure, but to come
2
as near as possible to measuring the blood pressure in an environment that is close to this, is why it is useful to take the measurement at home.
A. WHO blood pressure classifications
Standards for assessment of high or low blood pressure without regard to age, have been established by the World Health Organization (WHO), as shown in the chart.
* Figure No.1
B. Variations in blood pressure
Individual blood pressures vary greatly both on a daily and a seasonal basis. These variations are even more pronounced in hyper tense patients. Normally the blood pressure rises while at work and is at its lowest during sleeping period.
(Hyper tense: means a person who has high blood pressure symptom.)
The graph below illustrated the variations in blood pressure over a whole day with measurement taken every ¿ve minutes.
* Figure No.2
3
The thick line represents sleep. The rise in blood pressure at 4 PM (A in the graph) and 12 PM (B in the graph) correspond to an attack of pain.
3. Important information before use of the unit
Please rest for at least 5~10 minutes before taking the measurement.
To allow your blood vessels to return to the condition prior to taking the measurement, please wait at least 3~5 minutes between measurements. You may need to adjust the wait time according to your personal physiological situation.
If you have one of the circulatory problems as arteriosclerosis, diabetes, liver disease, kidney disease, severe hypertension,
peripheral circulation......, please consult your doctor or
healthcare professional before using the devices.
Wait 30 ~ 45 minutes before measurement if you’ve just consumed caffeinated beverages or smoked cigarettes.
Blood pressure measurements should be interpreted by a physician or trained health professional who is familiar with your medical history. By using the unit regularly and recording the results for your physician to interpret, you keep your physician informed of the continuing trends in your blood pressure.
Wind the cuff snugly around your wrist and the cuff must be at the same level as your heart.
Do not vibrate the unit during measurement, or the proper measurement will not be achieved.
4
Perform measurement quietly in a relaxed position.
Do not wind the cuff over jacket or sweater sleeve, or measurement cannot be done.
Keep in mind, that blood pressure naturally varies from time to time throughout the day and also is affected by lots of different factors such as smoking, alcohol consumption, medication and physical activity.
People with a condition that causes circulatory problems (diabetes, kidney disease, arteriosclerosis or poor peripheral circulation) may get lower readings with this monitor that with a blood pressure monitor that is used on the upper arm. Please consult your physician to determine if your wrist blood pressure accurately reÀects your actual blood pressure.
Blood pressure measurement determine with the unit are equivalent to those obtained by a trained observer using the cuff / stethoscope auscultation method. Within the limits prescribed by the Standard of EN 1060-4.
This product is not suitable for pregnant women.

5. Changing batteries
Remove the battery cover at the left side of the unit and insert batteries into the battery compartment in accordance with ribbon strip as shown, taking extreme care that the polarities + and - are observed.
Important notice: to take the batteries out easily, just pull the ribbon strip for help.
* Figure No.4
6. Attaching pressure cuff
A. Wrap the pressure cuff around the wrist.
a. The display of the unit should be placed on the palm side of the wrist.

It is extremely important for the measured values, that the cuff is at the same height of the heart.
Higher or deeper position will give deviations from the true value.
Measurement while sitting down:
a. Place your elbow on a table or other object (such as our carry case).
b. Use the armrest to position the arm so that the pressure cuff is at the same height as the heart.
c. Relax your hand with the palm facing up.
