Thank you for purchasing the Panasonic Wrist Blood Pressure
Monitor EW3002. Designed for easy, one-touch operation, this
monitor incorporates Precise Logic™ technology to provide
accurate, reliable measurements. It comes with a handy carrying
case that also serves as an armrest during measurement.
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.

Basics of Blood PressureYour 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.
Important Instructions Before Use1. 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. 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.
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 about 5 minutes before taking the
measurement.
 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.
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

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.
Positioning the Pressure CuffCAUTIONS:
 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.

your left hand.
2. Place the monitor on the palm side of your
wrist, roughly 1.5 cm (1/2) below your
palm as shown in Fig. 4, and secure it with
the hook-and-loop tape so that it fits
comfortably (is neither too tight nor too
loose).
3. Make sure that the display is on the inside
of your wrist (palm side up). Also, center
the unit on your wrist.Correct Position for Blood Pressure MeasurementWhen measuring your blood pressure at your wrist, the pressure cuff must be
at heart level to ensure consistent, accurate readings.Taking measurements while sitting down1. Place your elbow on a table.
2. Using the hard carrying case or other object as a support, position your
wrist at heart level.

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. Error
 If “E” (meaning error) appears in the display (Fig.12)
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. A measurement is automatically stored in the memory.
 Up to 21 measurements can be stored and recalled
later. After you have stored 21 measurements, the
oldest one will be deleted automatically when you
measure a new one.
4. To switch the unit off, press the Start (On/Off) button.
 The unit switches off automatically approximately 5 minutes after
measurement is completed.
Note:
 During the measurement, the unit may re-inflate once or twice in order to
start at the appropriate pressure level. This is normal and is not an
indication of a malfunction.

Measuring Your Blood PressureRelax during measurements.
1. To begin measurement, press the Start (On/Off) button (Fig. 7).
 The LCD display will show 888 and then switch to 0. The pressure cuff
will automatically inflate (Fig. 8).
 The pressure gradually decreases and when the pulse is detected, the
heart mark will blink (Fig. 10).Fig. 7 Fig. 8 Fig. 9 Fig. 102. When finished, the blood pressure measurement and the pulse rate
(number of beats per minute) are indicated on the display. The air in the
pressure cuff is then automatically released. If the measured values fall
within the hypertension range, the displayed values will blink for about 6
seconds (Fig. 11).R

the average value of these seven data will be displayed. If there is no
data in the memory or if there is only one data in the memory, the  A
will not be displayed.
2. By pressing the Recall button repeatedly (Fig. 15), you can browse through
all the stored data sequentially from the newest data to the oldest (Fig. 16).
 If no data is in the memory, nothing will be displayed.
Note:
Press the Recall button lightly and briefly. If the Recall button is pressed
continuously for more than about 2 seconds, all stored data will be deleted.
3. Press the Start (On/Off) button to finish.
 If the data is recalled while the blood pressure monitor is turned off, the
monitor will turn off automatically after about 30 seconds. Fig. 13 Fig. 14 Fig. 15 Fig. 16Deleting Data1. Press the Recall button.
2. Press the Recall button again until the recalled data disappears from the

IMPORTANT:
 WHO does not define a low blood pressure area. For reference, systolic
pressure readings of less than 90 mmH are considered to indicate low
blood pressure regardless of the diastolic pressure.
 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.Easily Check Your Blood Pressure Readings

About the Precise Logic™ Measurement SystemThe 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.
By using the Precise Logic™ measurement system, measurement reliability
and accuracy have been improved.

Care and Maintenance1. Use a dry, soft cloth to clean the device. If desired, use a cloth lightly
dampened with tap water and a mild detergent to clean the device. 
DO NOT use alcohol, benzene, thinner or other harsh chemicals to clean
the device or cuff.
2. When the unit will not be used for a long time (30 days or more), be sure to
remove the batteries. Otherwise, the batteries may leak and damage the
unit.Storing the MonitorFold the pressure cuff as shown in Fig. 17 and place the monitor into the hard
carrying case.

Symptom
The systolic pressure
value or diastolic
pressure value is high. The systolic pressure
value or diastolic
pressure value is low. The measured values
differ significantly.The measured value
differs from that
measured by the doctor.
The measured value is
different for each
measurement.The measured value
obtained is different from
that measured at the
upper arm.
Possible cause
 The hand with the cuff was held too low and
not at heart level. (See page 10.)
 The cuff was not attached properly. (See
page 9.)
 You moved your hand or body or you spoke
during measurement. (See page 10.) The hand with the cuff was held too high
and not at heart level. (See page 10.)
 You moved your hand or body or you spoke
during measurement. (See page 10.) Your posture was not the same for all
measurements, or measurements were
taken without sufficient time in between.
Always wait approximately 5 minutes before
taking another reading, and above all, relax. Blood pressure varies in response to minute
changes in your mental state, such as your
reaction to your doctor taking the
measurement. One way to check this is to
bring the unit to your doctor’s office and
directly compare the readings taken by your
physician.
 Relax for at least 5 minutes and then take
another measurement. For persons with certain circulation
problems, there may be substantial
differences in blood pressure values
measured at the upper arm versus at the
wrist.
If the device still appears to provide unusual or erroneous readings,
consult your physician. If the device does not appear to be functioning
properly, contact Panasonic at 1-800-338-0552
