• The following situations may cause substantial variations in blood  
pressure readings and should therefore be avoided at least 30 minutes  
prior to taking your blood pressure.  
Important Instructions Before Use  
1. Do not confuse self-monitoring with self-diagnosis. Blood pressure  
measurements should only be interpreted by a health professional who  
is familiar with your medical history.  
2. If you are taking medication, consult with your physician to determine  
the most appropriate time to measure your blood pressure. NEVER  
change a prescribed medication without first consulting with your  
physician.  
3. Blood pressure can vary based on many factors, including age, gender,  
weight and physical condition. In general, a person’s blood pressure is  
lower during sleep and higher when he or she is active. Blood pressure  
can change easily in response to physiological changes. The setting in  
which a person’s blood pressure is measured can also affect the results.  
Having one’s blood pressure measured by a healthcare professional in a  
hospital or clinic can cause nervousness and may result in a temporarily  
elevated reading. Because blood pressure measurements taken in a  
clinical setting can vary considerably from those taken at home, a  
person’s blood pressure should be measured not only occasionally in  
the doctor’s office, but also on a regular basis at home. Also, if you find  
that your blood pressure is lower at home, this is not unusual. To  
accurately compare with your physician’s reading, take your National  
blood pressure meter to your doctor’s office and compare readings in  
this setting.  
Blood pressure will be higher than usual:  
- when you are excited or tense  
- when you are taking a bath  
- during exercising or soon after exercising  
- when it is cold  
- within one hour after eating  
- after drinking coffee, tea or other beverages containing caffeine  
- after smoking tobacco  
- when your bladder is full  
Blood pressure will be lower than usual:  
- after taking a bath  
- after drinking alcohol  
6. Measurements may be impaired if this unit is used near a television,  
microwave oven, X-ray equipment or other devices with strong electrical  
fields. To prevent such interference, use the unit at a sufficient distance  
from such devices or turn the devices off.  
7. This unit is designed for use by adults. Consult with your physician  
before using this unit on a child. Do not use on infants or toddlers.  
8. This unit is not suitable for continuous monitoring during medical  
emergencies or operations.  
9. Do not use the unit for any purpose other than measuring blood  
pressure. Do not use the unit together with other devices.  
4. People suffering from cardiac arrhythmia, vascular constriction, liver  
disorders or diabetes, people with cardiac pacemakers or a weak pulse,  
and women who are pregnant should consult their physician before  
measuring their blood pressure themselves. Different values may be  
obtained due to their condition.  
10. Improper handling of batteries may result in battery rupture or in  
corrosion from battery leakage. Please observe the following to ensure  
proper use of batteries.  
a. Be sure to turn off the power after use.  
5. Try to take your blood pressure measurements at the same time and  
under the same conditions every day.  
b. Do not mix different types or sizes of batteries.  
c. Change all batteries at the same time. Do not mix old and new  
batteries.  
d. Be sure to insert batteries with correct polarity, as instructed.  
e. Remove batteries when they are worn out, and dispose of them  
properly according to all applicable environmental regulations.  
f. Do not disassemble batteries or throw them into a fire.  
g. Do not short-circuit batteries.  
• The ideal time to measure your blood pressure (to obtain your so-called  
“base blood pressure”) is in the morning just after waking up, before  
having breakfast and before any major activity or exercise. If this is not  
possible, however, try to take measurements at a specified time prior to  
breakfast, and before you have become active. You should relax for  
about 5 minutes before taking the measurement.  
h. Do not attempt to recharge the batteries included with the unit.

IMPORTANT:  
Precautions to Ensure Safe, Reliable Operation  
• WHO does not define a low blood pressure area.  
For reference, systolic pressure readings of less than 90 mmHg are  
considered to indicate low blood pressure regardless of the diastolic  
pressure.  
1. Do not drop the unit. Protect it from sudden jars or shocks.  
2. Do not insert foreign objects into any openings.  
3. Do not attempt to disassemble the unit.  
• Do not be alarmed by temporarily high or low readings because  
fluctuations in a person’s blood pressure are not uncommon. If possible,  
measure and record your blood pressure at the same time every day, and  
consult your physician if you have questions or concerns.  
• If abnormal variations in blood pressure are observed in measurement,  
please consult your physician.  
4. Do not crush the pressure cuff.  
5. If the unit has been stored at temperatures below 0°C, leave it in a warm  
place for about 15 minutes before using it. Otherwise, the cuff may not  
inflate properly.  
6. Do not store the unit in direct sunlight, high humidity or dust.  
Easily Check Your Blood Pressure Readings Against  
the World Health Organization (WHO) Guidelines  
About the Precise Logic™ Measurement System  
The blood flow (pulse wave) which influences blood pressure monitors  
varies according to the conditions of the blood vessels and the structure of  
the arm, making measurements by conventional methods difficult in some  
cases. For more consistent, accurate results, this device employs a Precise  
Logic™ measurement system that verifies both the height and width of the  
pulse wave in order to reliably measure blood pressure.

If your systolic pressure falls in one category but your diastolic pressure in  
another, your level is classified in the higher of the two categories.  
By using the Precise Logic™ measurement system, measurement reliability  
and accuracy have been improved.

Alarm function signals high blood pressure  
Blood pressure measurements for both systolic and diastolic readings are  
determined and indicated via a three-color LED system as being within  
normal or hypertensive ranges based on definitions and classification of  
blood pressure levels by the World Health Organization (WHO). Moreover,  
when blood pressure is in the high range, the reading displayed on screen  
flashes on and off to alert the user.

Instructions for correct measurement of blood pressure  
Measuring your blood pressure  
Measurement in a sitting position  
1. Press the ON/OFF/Start Button to  
turn on the unit.  
1. Rest your elbows on a table or  
other level surface.  
2. Make adjustments so that the  
height of the cuff and heart are at  
the same level.  
3. With the palm of your hand facing  
up release any tension held in your  
muscles.  
The LCD display will show 888 and  
then switch to 0. The cuff is auto-  
matically inflated.  
2. The blood pressure measurement is  
indicated along with the pulse rate  
(number of beats per minute). The  
air in the cuff is released automatically  
when the measurement is complete.  
Measurement in lying position  
1. Lie on your back with your body  
straight.  
3. Press the power switch to turn off the unit. If you forget to do so, the unit  
switches off automatically approx. 5 minutes after a measurement.  
• Do not lie on your side. Doing so  
will exert an uneven amount of  
force on one arm.  
2. With the palm of the hand facing up,  
extend your arm so that it is straight.  
Error  
If “E” (meaning error) appears in the display during  
measurement, an error has occurred, e.g., you have moved  
your hand during measurement. In this case, turn the unit off,  
wait at least 5 minutes and measure again.  
3. Relax and release any tension  
held in your muscles.  
IMPORTANT  
Take measurements at the same time everyday using the same arm  
and posture.  
CAUTION:  
• For persons with poor circulation resulting from diabetes, liver disease,  
arteriosclerosis, high blood pressure or other conditions, there may be  
significant differences in blood pressure values measured at the wrist  
versus at the upper arm.  
• Do not confuse self-monitoring with self-diagnosis.  
• NEVER change a prescribed medication without first consulting with  
your physician.  
• Measured readings will vary according to the height of the cuff.  
• Measurements taken in the morning should be done so upon waking and in  
the absence of an urge to urinate. If this should prove difficult, take  
measurements prior to breakfast while your body is still in an inactive state.  
• Do not touch the tube or the meter while measurement is in progress.  
Assume a natural posture, remaining calm and quiet when taking  
measurements  
• Rest for about 4 to 5 minutes before taking measurements.  
• Release any tension present in your body and refrain from muscle  
movement such as in the arm or fingers.  
• Do not speak while measurement is in progress.
