SAFETY PRECAUTIONS
Warning
• Self-diagnosis of your physical condition based on the measurement
results of the Base Unit is extremely dangerous. Make sure you
always consult your physician concerning your physical condition.
• Do not use a mobile phone or other device that emits radio waves in
the vicinity of the Base Unit while taking blood pressure readings. Do
not take blood pressure readings in the vicinity of a TV, microwave
oven, etc. Doing so can produce incorrect readings.
• Never use the Base Unit for any other purpose other than taking blood
pressure readings.
• Do not use the Base Unit to measure the blood pressure of young
children.
• Never try to take the Base Unit or cuff apart, and never modify them in
any way. Doing so can lead to malfunction of the Base Unit and other
serious problems.
Batteries
Incorrect use of batteries can cause corrosive fluid to leak from them,
and creates the risk of fire and personal injury due to exploding batteries.
To avoid such problems, make sure you carefully observe the following
battery guidelines.
• Always make sure that the (+)/(–) polarity of batteries is correct when
you load them.
• Never mix new batteries with old ones.
• Never mix batteries of different types.
• Be sure to remove the batteries from the Base Unit if you do not plan
to use it for a long time.
• Use only the batteries that are specifically recommended for the Base
Unit.
• Take care when using your fingernail to remove batteries from the
battery compartment. Pulling on batteries can cause long nails to
break.
KEEPING ATTUNED TO YOUR BLOOD
PRESSURE LEVELS
Your blood pressure is like a constant message from your body.
Monitoring your blood pressure provides you with vital feedback about
your current physical condition. High blood pressure, for example, often
shows no symptoms of its own, and so except for an abnormally high
measurement reading. Left undetected and untreated, high blood
pressure can often lead to more serious, life-threatening illness.
All of this means that daily blood pressure readings for the purpose of
detecting early warning signs from our bodies are an essential part of
any comprehensive personal health management program.
The CASIO Blood Pressure Monitor Watch and Base Unit make it
possible for you to take quick and easy blood pressure readings at
home and while you are out. Together, they provide you with
essential blood pressure data throughout the day.
At home While you are out
Watch
Base Unit
Base Unit
The Base Unit is a cuff type digital blood pressure monitor that measures
your systolic and diastolic blood pressure, as well as your pulse rate. It is
also used for setting basic data on the Watch.
Watch
This Watch measures blood pressure using a fingertip pulse wave
detection system. After you use the Base Unit to measure your basic
data and send it to the Watch, you can use the Watch to take readings,
without applying pressure to your upper arm. Simply place your finger
onto the Watch’s sensor and your blood pressure and pulse rate appear
in a few moments.
The Story of Blood Pressure
What is Blood Pressure?
Blood pressure represents the change in pressure against the interior of
artery walls, which is caused by blood being sent through the circulatory
system by each beat of the heart. There are actually two blood pressure
values: systolic blood pressure and diastolic blood pressure.
Systolic blood pressure is the pressure exerted by the blood when the
heart contracts, causing artery walls to expand.
Diastolic blood pressure, on the other hand, is the pressure exerted by
the blood when the heart expands, and artery walls return to their
original shapes.
What causes blood pressure to change?
A variety of different factors can cause a change in blood pressure,
including age, climate, emotional stress, gender, living environment, and
basic diet.
• Average systolic blood pressure tends to rise with age due to natural
loss of elasticity in arterial walls.
Handling
• Do not use the Base Unit if it appears to be malfunctioning, damaged,
etc.
BP-1M-2
• Your blood pressure fluctuates throughout the day. Normally, it is at its
highest shortly after you awake in the morning, and it reaches its
lowest level some time while you are asleep. A fluctuation between
maximum and minimum systolic blood pressure levels of about
20mmHg is considered normal.

Time
The above is upper arm blood pressure data.
• A rise in blood pressure can be caused by physical exercise, drinking
coffee or tea, smoking, the need to urinate, and other factors.
• Blood pressure is also affected by your physical condition, as well as
stress due to your emotional state, worry, etc.
• A blood pressure reading can also be affected by your posture when
the reading is taken. Normally, your blood pressure will be lower if you
are sitting instead of standing.
• Temperature and humidity can also affect blood pressure. Normally,
winter blood pressure readings tend to be higher than summer
readings.
Definitions and Classification of Blood Pressure Levels
Though the general rule of thumb for normal systolic (maximum value)
blood pressure is your current age plus 90, this is not always necessarily
true. The following chart shows some general guidelines for blood
pressure values.
• The following tables show classifications for hypertension (high blood
pressure) according to the World Health Organization (WHO) and the
International Society on Hypertension (ISH) (1999).
Diastolic Blood
Pressure (mmHg)
Up to 80
80 to 84

Grade 2 Hypertension (“moderate”)
Grade 3 Hypertension (“severe”)
140 to 159
140 to 149
160 to 179
180 or
greater
• When diastolic blood pressure is up to 90mmHg, systolic blood
pressure greater than 140mmHg is classified as Isolated Systolic
Hypertension, while systolic blood pressure within the range of 140 to
149mmHg is classified as Subgroup: Borderline Isolated Systolic
Hypertension.

Why is high blood pressure a cause for concern?
As its name implies, high blood pressure causes arteries to be exposed
to high pressure, and can cause lesions in the arteries that supply blood
to brain, heart, liver, and other vital organs. Left untreated, high blood
pressure can lead to loss of heart function, hardening of the arteries, and
a host of other problems like those described below.
• Aneurysms in the brain’s blood vessels, which can lead to stroke
• Enlargement of the heart, which can lead to heart failure
• Narrowing of blood vessels in the kidney, which can lead to kidney
failure
• Premature hardening of the arteries throughout the body, especially
those in the heart, brain, and kidneys, which can lead to heart attack,
stroke, or kidney failure
What does low blood pressure indicate?
Some symptoms of low blood pressure are chronic fatigue, dizziness,
shoulder stiffness, palpitation of the heart, and shortness of breath. Be
sure to contact your physician if you suffer from any of these symptoms.
Monitoring Blood Pressure Levels on Your Own
When is the best time to take readings?
You should take readings during which you are most relaxed and stable.
It is also important to take readings at the same times everyday, every
morning, noon, and night, for example. Of course, you can also take
readings at any other time you wish, but the important thing is to take
blood pressure readings an integral part of your overall health control
activities.
Be sure to keep records.
Your blood pressure will fluctuate with changes in your physical
condition and even the weather. Because of this, you should keep a
record that includes not only measured values, but also information
about your physical condition and surrounding conditions. Try making it
your goal to build an entire year of daily records.
• You can make copies of the “BLOOD PRESSURE RECORD” at the
back of this manual and use them to keep track of changes in your
blood pressure and pulse measurements.
Is there anything I should do before taking a reading?
First of all, try to relax. Take five or six deep, cleansing breaths. Also,
note the following pointers.
Take readings in a quiet location.
Select a comfortable location that is free of loud noise and vibration, and
is neither overly hot nor cold. A temperature of about 20°C is best.
Take readings while you are calm.
Avoid times when you are worried or otherwise emotionally upset, and
after eating, exercise, or drinking coffee.
Maintain good posture during readings.
Keep your arm and wrist at about the same height as your heart. It is
also important to be free if tension.
Take readings at the same time everyday.
Remember that blood pressure is constantly changing. Try to take your
readings at the same time each day.
Why are values produced by readings I take at home
different from values produced when my doctor takes
readings?
Slight tension caused by a visit to the doctor or a hospital can cause
blood pressure readings taken there to be a bit higher. This, of course,
assumes that you are following the correct procedures when taking your
readings at home.
It could be due to a condition called “white-coat hypertension.”
“White-coat hypertension” is a condition caused by the atmosphere that
is present in a hospital. It is an emotional condition, and does not
indicate a physical problem. It is important to be relaxed while taking a
blood pressure reading.
Controlling Blood Pressure
Daily Life
How you live your daily life is an important factor in achieving good blood
pressure. Improved living habits and patterns can actually decrease the
chance of high blood pressure. The first step on the road to proper living
is eliminating overexertion and stress.
The following are some proven tips for developing good living habits and
enjoying the benefits of good blood pressure.
• Reduce salt intake.
• Go to bed early and get up early.
• Eat regular meals every morning, noon, and night.
• Get enough sleep.
• Set aside enough time for yourself in order to get some stress relief.
• Try to achieve a balance between your mental and physical well
being.
BP-1M-3
Exercise
Proper exercise plays an important role in controlling blood pressure.
The accent here is on the word “proper,” because the wrong type of
exercise can actually do more harm than good. Aerobic exercise, such
as walking at a comfortable pace, is the best for controlling blood
pressure.
Healthy Walking Tips
Keep your gaze on the ground
relatively far in front of you.
Keep your chin in.
Walk briskly in
a straight line.
Lower your foot to
the ground heel first.
Other things to remember when exercising!
• Keep it brisk, but don’t overdo it!
• Don’t forget to warm up and cool down.
• Be sure to drink water to replenish lost fluids.
• Try to stick to indoor exercises on very hot or very cold days.
Important!
• Always consult with your physician before undertaking any physical
exercise program.
Keep your head upright and
pointed straight ahead.
Keep your chest out
and your back straight.
Take long strides.
Let your arms swing
forward and back.

# Slide the battery compartment cover back into place to close it.
• If display contents appear abnormal after you load batteries,
remove the batteries, wait for about two or three seconds, and then
reload them.
AFFIXING THE CUFF TO YOUR ARM
• Affix the cuff to your arm so it is in contact with bare skin.
• If you are wearing clothing made of thick material (such as a sweater),
it is better to remove the thick clothing than to roll up the sleeve.
! Insert the plug of the cuff into the Base
Unit.
• Make sure you insert the plug as far
as it will go.
# Pull on the end of the cuff material until the cuff is snug on your arm,
and use the fastening tape to secure it in place.
Tighten the cuff until
all of the open space
between your arm and
the cuff is eliminated.
• Take care that you
do not over tighten
the cuff.
Fastening tape
• Leaving space between the cuff and your arm, can cause over
inflation, and apply very strong pressure to your arm. It can also
interfere with proper measurement.
$ With your hand open and the palm facing upwards, place your elbow
on a table or other surface so the center of the cuff is at about height
as your heart.
Center of cuff
• If the center of the cuff is too low, try putting a towel or cushion
under your elbow.
• Make sure that the air tube does not pass under your arm.
Yes! No!
Plug
Connector
@ Widen the opening of the cuff and then slip it over your left arm.
The cuff material should form a
loop, with the end of the material
passing through the oblong metal
ring. Pull the end of the material
through the ring so the cuff is
snug on your arm, double it back
against the ring, and secure it in
place with the fastening tape.
If the end of the material is
accidentally pulled out from
the metal ring, insert it back
in, making sure that the
fastening tape is facing
outward.
There should be about one
or two centimeters between
the edge of the cuff and
your elbow joint.
• The cuff should not be
touching your elbow joint.
Your hand should be open,
palm facing upwards.
Position the cuff so the air tube is
located at the top of your biceps.
• The tube should align
approximately with your middle
finger.
• Always have the cuff on your left arm whenever taking readings for
the purpose of setting the Watch’s basic data. If you are simply
taking readings with the Base Unit only, however, you can have the
cuff on your right arm.
TAKING A BLOOD PRESSURE READING
• Make sure you are relaxed before starting the measurement procedure.
• Do not move your arm or the rest of your body while a measurement
is in progress.
! Put the cuff on your arm and set the PRESET PRESSURE switch to
the estimated upper limit of your systolic (high) blood pressure value.
180 210150
• If you think your systolic blood pressure is around 130, you should
select 150 as the PRESET PRESSURE setting.

% Press the ON/OFF button to turn off the Base Unit.
• An Auto Power Off feature automatically turns off the Base Unit if
you leave it on for about three minutes.
Note
• Avoid taking too many consecutive measurements with the Base Unit.
Pressure from the Base Unit cuff can cut off circulation in your arm
and cause incorrect readings. Remove the cuff and wait a while before
taking another reading.
• Correct readings are impossible when diastolic blood pressure is
greater than 180mmHg.
Re-inflation
If the Base Unit determines that pressure in insufficient during a
measurement operation, it automatically re-inflates the cuff. Re-inflation
may also be performed if you move or talk, or if there is excessive noise
or another type of disturbance during a measurement procedure.
• Note that positioning the cuff so its air tube underneath your arm
(especially when your arm is pressing down on the tube) can cause
noise. This can lead to re-inflate or even make proper measurement
impossible.
Stopping a Measurement
To stop an ongoing measurement operation, press the START button.
This causes the Base Unit to deflate the cuff and then go into standby.
Pressing the ON/OFF button also causes the Base Unit to deflate the
cuff and turn off.
