Introduction  
Important Instructions Before Use  
Thank you for purchasing the Panasonic Wrist Blood Pressure Monitor  
EW3003.  
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.  
Measuring your own blood pressure is an important way of monitoring your  
health. High blood pressure (hypertension) is a major health problem which  
can be treated effectively once detected. Measuring your blood pressure  
between doctor visits on a regular basis in the comfort of your home, and  
keeping a record of the measurements, will help you monitor any significant  
changes in your blood pressure. Keeping an accurate record of your blood  
pressure will help your doctor diagnose and possibly prevent any health  
problems in the future.  
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. For persons with irregular or unstable circulation resulting from diabetes,  
liver disease, arteriosclerosis or other medical conditions, there may be  
variations in blood pressure values measured at the wrist versus at the  
upper arm. Monitoring the trends in your blood pressure taken at either  
the arm or the wrist is nevertheless useful and important.  
4. 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 Panasonic blood pressure  
monitor to your doctor’s office and compare readings in this setting.  
Basics of Blood Pressure  
Your heart acts like a pump, sending blood surging through your blood  
vessels each time it contracts. Blood pressure is the pressure exerted by  
blood pumped from the heart on the walls of blood vessels. Systolic  
pressure is the pressure exerted when the heart contracts and pumps blood  
into the arteries. Diastolic pressure is the pressure exerted when the heart  
expands, or relaxes. When you or your doctor take your blood pressure,  
both your systolic and diastolic pressures are measured. If your blood  
pressure measurement is 120 over 80 (120/80), for example, your systolic  
pressure is 120 while your diastolic pressure is 80.  
5. 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.  
6. Try to take your blood pressure measurements at the same time and  
under the same conditions every day.  
• 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  
3
4
 
about 5 minutes before taking the measurement.  
Precautions to Ensure Safe, Reliable Operation  
• 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.  
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.  
Blood pressure will be higher than usual:  
- when you are excited or tense  
- when you are taking a bath  
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.  
- 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  
6. Do not store the unit in direct sunlight, high humidity or dust.  
- when your bladder is full  
Blood pressure will be lower than usual:  
- after taking a bath  
- after drinking alcohol

IMPORTANT:  
Inserting/Replacing Batteries  
• 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.

Positioning the Pressure Cuff  
Correct Position for Blood Pressure Measurement  
When measuring your blood pressure at your wrist, the pressure cuff must  
be at heart level to ensure consistent, accurate readings.  
Always rest for about four to five minutes before taking measurements.  
Press the On/Off and Start button to start a measurement. The cuff will  
automatically inflate and then deflate when the measurement is complete.  
CAUTIONS:  
• Do not use the unit for any purpose other than measuring blood  
pressure. Also, do not use the unit in conjunction with other devices.  
Improper use may cause a malfunction or personal injury.  
• Keep the unit out of the reach of children.

If the blood pressure monitor is  
positioned lower than the heart, the  
measured blood pressure value  
may be high.  
If the blood pressure monitor is  
positioned higher than the heart,  
the measured blood pressure value  
may be low.  
IMPORTANT:  
• Measure your blood pressure at the same time and under the same  
conditions every day if possible. The ideal time to measure your blood  
pressure is in the morning immediately after waking up, while you are still  
relatively calm. If this is not possible, try to take your blood pressure prior  
to breakfast, before you become active.  
• Relax and take measurements in a comfortable position.  
• Rest for at least 5 minutes before taking a measurement.  
• Keep still and do not speak during measurement. Blood pressure can  
fluctuate with the slightest change, such as tensing your muscles or  
changing your posture.  
If the posture applies pressure to  
the stomach (leaning forward),  
accurate measurements may not  
be possible.  
Do not touch the blood pressure  
monitor while taking  
measurements.  
Do not move your body, your arm,  
or your fingers while taking  
measurements.  
Do not talk while taking  
measurements.  
Do not use close to cellular phones or other devices which emit  
electromagnetic waves. Doing so may result in malfunction.

allow a rest period of 4 to 5 minutes before starting again.  
4. Press the On/Off and Start button to switch off the unit  
(Fig. 6-e).  
• If you wish to make another measurement, switch off and  
wait for 4 to 5 minutes before performing another one.  
• If you forget to switch the unit off, it will do so  
automatically after approx. 5 minutes.  
Please consult your doctor without delay if the blood  
pressure indicator repeatedly draws attention to elevated  
blood pressure values.

Calling up readings from memory  
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.

Readings can be recalled after being saved without  
having to switch the unit on.  
1. Press the Memory/Recall button.  
• The average readings of all recorded measurements  
are displayed.  
• Do not confuse self-monitoring with self-diagnosis.  
• NEVER change a prescribed medication without first consulting with  
your physician.  
• The

• When, for example, readings from 21 measurements  
have been saved the average of the readings from 21  
measurements will be displayed.
