Introduction
1Thank you for purchasing the Panasonic Upper Arm Blood Pressure
Monitor EW3111. Designed for easy, one-touch operation, this monitor
incorporates Precise Logic™ technology to provide reliable measurements.
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 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.

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.
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.
5. 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
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.
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.
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.
h. Do not attempt to recharge the batteries included with the unit.

Precautions to Ensure Safe, Reliable Operation
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.
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.
IMPORTANT:
•WHO does not define a low blood pressure area.
For reference, systolic pressure readings of less than 90 mmHgare
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 Against
the World Health Organization (WHO) Guidelines
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.

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.
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.
According to WHO guidelines, values consistently in excess of 140 mmHg
(Sys.) and/or 90 mmHg(Dia.) are considered to constitute high blood pressure.
High blood pressure is a health risk and must be treated without fail.
Please consult your doctor without delay if the blood pressure indicator
repeatedly draws attention to elevated blood pressure values.

Fitting the Blood Pressure Monitor
1. Attaching the cuff to the upper
arm.
•Make sure the cuff is wrapped so
that it is in contact with the skin.
Measurements may be taken
from either the left or right 
arm. However, please take
measurements using the same
arm each time, because there
is said to be a blood pressure
difference of approx. 10 mmHg
between the left and right. 
2. Fasten firmly, but not too tight.
•Optimally, there should be enough
room to insert one finger between
the cuff and arm.
•Make sure your sleeve does not
get in the cuff.
•Firmly attach using the hook-and-
loop tape.Positioning on the Upper Left Arm
•Position so that 
the tube extends in
line with the little finger
on the palm side.

Instructions for correct measurement of blood pressure
IMPORTANT
Take measurements at the same time everyday using the same arm
and posture.
•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.
Measurement in a sitting position
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.
Measurement in lying position
1.Lie on your back with your body
straight. 
•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.
3.Relax and release any tension
held in your muscles.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.
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.

Model EW3111 is intended to be used for the oscillometric PRECISE
LOGIC™measurement of systolic and diastolic blood pressure and pulse
rate using a pressurized cuff.
Blood pressure measurements determined with this device are equivalent
to those obtaind by a trained observer using the cuff/stethoscope
auscultation method, within the limits prescribed by the American National
Standard, Electronic or automated sphygmomanometers.
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.Possible cause
•The cuff was held too low, i.e. not at heart level.
(See page 11)
•The cuff was not attached properly. (See page 10)
•You moved your body or you spoke during
measurement. (See page 11)
•The cuff was held too high, i.e. not at heart level.
(See page 11)
•You moved your body or you spoke during
measurement. (See page 11)
•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.
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
