Panasonic Oscillometric Diagnostec ™ Portable Automatic Arm Blood
Pressure Monitor Model EW3109 is a device intended to measure
systolic and diastolic blood pressure and pulse rate of an adult
individual by using a pressurized cuff on the arm. The device is not
intended for use on infants and children. The device is designed
for home use only, not for ambulatory measurement (measurement
recorded continuously during the day).
Specification of this device including pulse rate (30 - 160 pulse/min.
+/- 5%) are listed in page 19.
Blood pressure measurements determined with this device are
equivalent to those obtained by a trained observer using the cuff/
stethoscope auscultation method, within the limits prescribed by
the American National Standard, Manual, Electronic or automated
sphygmomanometers.
If you suffer from disorder of heart rhythm, known as arrhythmia only
use this blood pressure monitor in consultation with your doctor. In
certain cases oscillometric measurement method can produce incorrect
readings.
Flashing System for hypertensive readings are based on blood
pressure values classified in the paper: “JNC 7 Express; The Seventh
Report of the Joint National Committee on Prevention, Detection,
Evaluation and Treatment of High Blood Pressure; U.S. DEPARTMENT
OF HEALTH AND HUMAN SERVICES; National Institute of Health;
National Heart, Lung, and Blood Institute; National High Blood Pressure
Education Program; NIH Publication No. 03-5233; May 2003.” The
display values are generally known, but not proven, to be an indicator
of your blood pressure.
The EW3109 is not intended to be a diagnostic device. Contact your
physician if prehypertensive or hypertensive values are indicated.

Introduction
Thank you for purchasing the Panasonic Portable Automaic Arm Blood
Pressure Monitor EW3109.
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 Panasonic blood pressure
monitor 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:
4

- 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
- when in a moving vehicle
Blood pressure will be lower than usual:
- after taking a bath
- after drinking alcohol

• Insert the pressure cuff plug all the way
in.
2. Wrap the cuff around upper arm.
• Remove your shirt or roll up your sleeve
so that the cuff will be on your bare skin.
• If rolling up your sleeve causes con¬
striction on your arm, remove your shirt
for measurements.
— ^
The blood pressure monitor can be
used by wrapping the cuff on either
upper arm. However, since it has
been said that the difference in blood
pressure between the left and right
arms may be around lOmmHg, be
sure to always use the same arm for
measurements.
v_
When wrapping around right arm
Approximately 2 to 3cm
(25/32" to 1-3/16”) from
inside of elbow
Fasten so that there is no gap between
the cuff and the arm, but be careful that
the cuff is not too tight.
Be careful not to catch your clothes
when wrapping the cuff. (Doing so may
lead to lower accuracy.)
Press the tape fastener down well.
12

For Accurate Measurements
Take measurements while sitting quietly and relaxing.
1. R est your elbows on a table, etc.
2. P osition your arm so that the pressure
cuff is at the same height as your
heart.
3. P osition your palm upward, and relax
your hand.
Take measurements using the same upper arm in the same position at
the same time every day.
• Measurement values will vary according to the height of the pressure cuff.
• Take measurements in the morning immediately after you wake up, when
there is no urge to urinate. If this is difficult, take measurements before
breakfast and before you have moved a lot.
Relax and sit in a natural posture when taking measurements.
• Always sit quietly for approximately 4 to 5 minutes before taking
measurements.
• Relax your body, arm, and fingers and do not move their muscles.
• Do not talk while taking measurements.
• During measurement, do not touch the main body or the tube.
CAUTION:
Keep away from cellular telephones and other sources of electromagnetic
radiation. Failure to do so could result in malfunctioning.
13

Cautions During Measurements
In the following situations, accurate measurements cannot be taken.
Within 1 hour of eating or
drinking alcohol
Immediately after drinking coffee
or tea, or smoking
Immediately after exercising In a moving vehicle
or taking a bath
measurement while staying quiet.
In cold places
Take measurements at ambient
temperatures of 10°C to 40°C
(50°F to 104°F).
When you need to urinate
Wait several minutes after urinating
before taking measurements.

The entire display will light for approximately
1 second.
• If there is air left in the pressure cuff, the
fully lit time will be longer.
The heart mark V will blink when pulse is
detected during pressurization.
C I ^
In the process of pressurization, changes in
pressurization speed and operating sounds
are normal and necessary for the purpose
of measurement during pressurization.
2. W hen measurement has been completed, the
blood pressure and pulse values will be displayed.
• Pressure will be automatically released
from the pressure cuff.
• If the measured value is in the high
blood pressure region, the values will
blink (for approximately 6 seconds).
(For how to read the blood pressure
display, see p. 16.)
The CM] mark will blink. (For storing measure¬
ment values, see p. 17.)
The pulse rate value is the beats per minute
calculated based on the pulse rate during
measurement.
3. T o switch off the blood pressure monitor, press
the On/Off Start button.
• If you forget to switch it off, the blood pres¬
sure monitor will switch off automatically after
approximately 5 minutes.

Please consult your doctor without delay if the blood pressure indicator
repeatedly draws attention to elevated blood pressure values.
Advice:
In general, blood pressure measurements are lower for the second
measurement because you are less nervous and are more tranquil.
For people who easily get tense, measuring twice each time is very effective.
When two measurements are taken, normally the smaller measurement is
stored.
When taking two measurements, always stay quiet for 4 to 5 minutes after
the first measurement before taking the second measurement.
