Greetings
Congratulations on purchasing a state-of-the-art A&D blood pressure
monitor. Designed for ease of use and accuracy, this monitor will facilitate
your daily blood pressure regimen. We recommend that you read
through this manual carefully before using the monitor for the rst time.
Intended Use
• The monitor is designed for use on adults only. Do not use on
newborns or infants.
• Environment for use: This monitor is intended for home healthcare
environment.
• This monitor is designed to measure blood pressure and pulse rate
of people for diagnosis.
Precautions
• Precision components are used in the construction of this monitor.
Extremes in temperature, humidity, direct sunlight, shock or dust
should be avoided.
• Clean the monitor and cuff with a dry, soft cloth or a cloth dampened
with water and a neutral detergent. Never use alcohol, benzene,
thinner or other harsh chemicals to clean the monitor or cuff.
• Avoid tightly folding the cuff or storing the hose tightly twisted for long
periods, as such treatment may shorten the life of the components.
• The monitor and cuff are not water resistant. Prevent rain, sweat and
water from soiling the monitor and cuff.
• Measurements may be distorted if the monitor is used close to
televisions, microwave ovens, cellular telephones, X-ray or other
devices with strong electrical elds.
• When using the monitor, conrm that the monitor is clean.
• Used equipment, parts and batteries are not treated as ordinary
household waste, and must be disposed of according to the
applicable local regulations.

• When the AC adapter is used, make sure that the AC adapter can
be readily removed from the electrical outlet when necessary.
• Do not modify the monitor. It may cause accidents or damage to the
monitor.
• To measure blood pressure, the arm must be squeezed by the cuff
hard enough to temporarily stop blood ow through the artery. This
may cause pain, numbness or a temporary red mark to the arm.
This condition will appear especially when measurement is repeated
successively. Any pain, numbness, or red marks will disappear with
time.
• Take care to avoid accidental strangulation of babies or infants with
the hose and cable.
• Do not twist the air hose during measurement. This may cause
injury due to continuous cuff pressure.
• Wireless communication devices, such as home networking
devices, mobile phones, cordless phones and their base stations,
walkie-talkies can affect this blood pressure monitor. Therefore, a
minimum distance of 30 cm (12") should be kept from such devices.
• Measuring blood pressure too frequently may cause harm due to
blood ow interference. Check that the operation of the monitor
does not result in prolonged impairment of blood circulation, when
using the monitor repeatedly.
• If you have had a mastectomy, please consult a doctor before using
the monitor.
• Do not let children use the monitor by themselves and do not use
the monitor in a place within the reach of infants. It may cause
accidents or damage.
• There are small parts that may cause a choking hazard if swallowed
by mistake by infants.
• Do not apply the cuff on an arm in which another medical device is
attached. The equipment may not function properly.
Precautions

• People who have a severe circulatory decit in the arm must consult
a doctor before using the monitor, to avoid medical problems.
• Do not self-diagnose the measurement results and start treatment by
yourself. Always consult your doctor for evaluation of the results and
treatment.
• Do not apply the cuff on an arm with an unhealed wound.
• Do not apply the cuff on an arm receiving an intravenous drip or
blood transfusion. It may cause injury or accidents.
• Do not use the monitor where ammable gases such as anesthetic
gases are present. It may cause an explosion.
• Do not use the monitor in highly concentrated oxygen environments,
such as a high-pressure oxygen chamber or an oxygen tent. It may
cause a re or explosion.
• Unplug the AC adapter when not in use during the measurement.
• Use of accessories not detailed in this manual may compromise
safety.
• Should the battery short-circuit, it may become hot and potentially
cause burns.
• Allow the monitor to adapt to the surrounding environment before
use (about one hour).
• Clinical testing has not been conducted on newborn infants and
pregnant woman. Do not use on newborn infants or pregnant
woman.
• Do not touch the batteries, the DC jack, and the patient at the same
time. That may result in electrical shock.
• Do not inate without wrapping the cuff around the upper arm.

Using the Monitor
Applying the arm cuff
1. Wrap the cuff around the upper arm, about 0.5" (1-2 cm) above the
inside of the elbow, as shown.
2. Place the cuff directly against the skin, as clothing may cause a faint
pulse and result in a measurement error.
Constriction of the upper arm, caused by rolling up a shirtsleeve,
may prevent accurate readings.
3. Conrm that the index p points within the proper t range.
Note: During measurement, it is normal for the cuff to feel very tight.

E-12
Taking your Blood Pressure
This blood pressure monitor is designed to detect the pulse and to
inate the cuff to a systolic pressure level automatically.
Tips for Taking Blood Pressure
Before Your Measurement:
• For 30 minutes prior to taking your blood pressure
»Do not exercise
»Do not drink coffee, caffeinated soda or alcohol
»Do not smoke
• Sit quietly for 5-10 minutes
• Ensure you are using the right size cuff
During Your Measurement:
• Do not talk
• Sit with your back straight and supported
• Uncross your legs and place feet at on oor
• Rest arm on a table so that the cuff is at heart level
• Measure two times a day, in the morning and evening
Notes for Accurate Measurement
• This monitor bases its measurements on the heartbeat. If you have
a very weak or irregular heartbeat, the monitor may have difculty
determining your blood pressure.
• Should the monitor detect a condition that is abnormal, it will stop
the measurement and display an error symbol. Refer to the section
"Symbols" for the description of the symbols.
• If you have emotional stress, the measurement will reect this stress
as a higher (or lower) than normal blood pressure reading and the
pulse reading will usually be faster than normal.
• An individual's blood pressure varies constantly, depending on what
you are doing and what you have eaten. What you drink can have a
very strong and rapid effect on your blood pressure.

the cuff to feel very tight. A pressure
bar indicator is displayed, as in the
gure at the right, during ination.
Note: If you wish to stop ination at any time, press
the START button again.
3. When ination is complete, deation
starts automatically and the
(heart mark) blinks, indicating that
the measurement is in progress.
Once the pulse is detected, the
mark blinks with each pulse beat.
Note: If an appropriate pressure is not obtained, the
monitor starts to inate again automatically.
4. When the measurement is
complete, the systolic and diastolic
pressure readings and pulse rate
are displayed. The cuff exhausts
the remaining air and deates
completely.
5. Press the START button again to
turn off the power.
Note: This product is provided with an automatic power shut-off function, which turns the power
off approximately one minute after measurement.

E-16
IHB/AFib Indicator
When the monitor detects an irregular rhythm during the
measurements, the IHB/AFib indicator will appear on the display with
the measurement values.
Note: We recommend contacting your physician if you see this IHB/AFib indicator
frequently.
What is AFib?
The heart contracts due to electrical signals occurring in heart and
sends blood through the body. Atrial brillation (AFib) occurs when
the electrical signal in the atrium becomes confused and leads to
disturbances in the pulse interval. AFib can cause blood to stagnate in
the heart, which can easily create clots of blood, a cause of stroke and
heart attack.

About Blood Pressure
What is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the
arteries. Systolic pressure occurs when the heart contracts. Diastolic
pressure occurs when the heart expands. Blood pressure is measured
in millimeters of mercury (mmHg). One’s natural blood pressure is
represented by the fundamental pressure, which is measured rst thing
in the morning while one is still at rest and before eating.
What is Hypertension and How is it Controlled?
Hypertension, an abnormally high arterial blood pressure, if left
unattended can cause many health problems including stroke and heart
attack. Hypertension can be controlled by altering lifestyle, avoiding
stress, and with medication under a doctor’s supervision. To prevent
hypertension or keep it under control:
Why Measure Blood Pressure at Home?
Blood pressure measured at a clinic or doctor’s ofce may cause
apprehension and can produce an elevated reading, 25 to 30 mmHg
higher than that measured at home. Home measurement reduces the
effects of outside inuences on blood pressure readings, supplements
the doctor’s readings and provides a more accurate, complete blood
pressure history.
• Do not smoke
• Reduce salt and fat intake
• Maintain proper weight
• Exercise regularly
• Have regular physical
checkups

E-19
Blood Pressure Variations
An individual’s blood pressure
varies greatly on a daily and
seasonal basis. It may vary by
30 to 50 mmHg due to various
conditions during the day. In
hypertensive individuals variations
are even more pronounced.
Normally, the blood pressure rises
while at work or play and falls to
its lowest levels during sleep. So,
do not be overly concerned by the
results of one measurement.
Take measurements at the same time every day using the procedure
described in this manual to get to know your normal blood pressure.
Regular readings give a more comprehensive blood pressure history.
Be sure to note the date and time when recording your blood pressure.
Consult your doctor to interpret your blood pressure data.
