Instruction Manual

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 use by individuals
in a 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 cu󰀨 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 cu󰀨.
• Avoid tightly folding the cu󰀨 or storing the hose tightly twisted for long
periods, as such treatment may shorten the life of the components.
• The monitor and cu󰀨 are not water resistant. Prevent rain, sweat and
water from soiling the monitor and cu󰀨.
• 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 cu󰀨
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.
• Do not twist the air hose during measurement. This may cause injury
due to continuous cu󰀨 pressure.
• Wireless communication devices, such as home networking devices,
mobile phones, cordless phones and their base stations, walkie-
talkies can a󰀨ect 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 cu󰀨 on an arm in which another medical device is
attached. The equipment may not function properly.
• People who have a severe circulatory decit in the arm must consult
a doctor before using the monitor, to avoid medical problems.
Precautions

• 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 cu󰀨 on an arm with an unhealed wound.
• Do not apply the cu󰀨 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 AC Adapter jack, and the patient at
the same time. That may result in electrical shock.
• Do not inate without wrapping the cu󰀨 around the upper arm.

Using the Monitor
Selecting the Correct Cu󰀨 Size
Using the correct cu󰀨 size is important for an accurate reading. A cu󰀨
that is too large will produce a reading that is lower than the correct
blood pressure; a cu󰀨 that is too small will produce a reading that is
higher than the correct blood pressure. With your arm hanging at the
side of your body, measure the circumference of your upper arm at the
midpoint between the shoulder and elbow.

9.4-14.2" (24-36 cm) Medium Cu󰀨 UA-280A
The Extra Large Cu󰀨 is designed to accommodate larger arm sizes
measuring from 16.5-23.6" (42-60 cm). This cu󰀨 is contoured to
provide you with a quick and comfortable t.
Applying the arm cu󰀨
1. Wrap the cu󰀨 around the
upper arm, about 0.5” (1-2 cm)
above the inside of the elbow,
as shown.
2. Place the cu󰀨 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.

Taking your Blood Pressure
This blood pressure monitor is designed to detect the pulse and to
inate the cu󰀨 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 co󰀨ee, ca󰀨einated soda or alcohol
»Do not smoke
• Sit quietly for 5-10 minutes
• Ensure you are using the right size cu󰀨
During Your Measurement:
• Do not talk
• Sit comfortably with your back straight and supported
• Uncross your legs and place feet at on oor
• Rest arm on a table so that the cu󰀨 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 di󰀩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 e󰀨ect on your blood pressure.
• The monitor performance may be a󰀨ected by excessive temperature or
humidity, or altitude.

E-15
Taking Your Blood Pressure
Normal Measurement
1. Place the cu󰀨 on the arm (preferably the left arm). Sit quietly during
measurement.
2. Press the START button. The average of your last 3 readings and
the total number of readings in memory will appear. As the cu󰀨
pressurizes, measurement will begin and the Cu󰀨 Ination Meter will
show on the display screen. It is normal for the cu󰀨 to feel very tight.
Note: If an appropriate pressure is not obtained, the monitor automatically starts to inate
again. If you wish to stop ination at any time, press the START button again.
3. When the measurement is complete, the systolic and diastolic
pressure readings and pulse rate are displayed. The cu󰀨 deates
and the monitor automatically shuts o󰀨 after 1 minute, or you can
turn it o󰀨 by pressing the START button.
4. Remove cu󰀨 and make note of your blood
pressure and pulse rate.
Manual override of systolic pressure
setting:
If your systolic pressure is expected to exceed 230
mmHg follow these steps:
1. Place the cu󰀨 on the left arm, unless your physician tells you
otherwise.
2. Press and hold the START button until a number 30 to 40 mmHg
higher than your expected systolic pressure appears.
3. Release the START button when the desired number is reached.
280 mmHg is the highest pressure level the monitor can reach.
Measurement will then begin. Continue to measure your blood
pressure.

E-16
Taking Your Blood Pressure
The Cu󰀨 Ination Meter is located on the left side of the display screen
to tell you when the blood pressure monitor is inating and deating
the cu󰀨. The Cu󰀨 Ination Meter moves up during ination and moves
down during deation.
Average Reading
This monitor provides an average of the
last 3 blood pressure readings. When
taking a measurement, the average
blood pressure reading will appear and
ash several times before the cu󰀨 begins
to inate. The average blood pressure
reading will also appear briey when
you recall the measurements stored in
memory.

Memory
This monitor automatically stores up to sixty (60) blood pressure and
pulse measurements in memory. Measurements stored in memory are
assigned an index number in the order of the newest to the oldest.
To retrieve readings, follow these simple steps:
1. When the display screen is showing only the
time, press and quickly release the Memory
(“M”) button. You will see the date (month and
day) and time of the most recent blood pressure
that was taken followed by the measurement.
2. If you want to retrieve other measurements in
memory, press and release the Memory button
repeatedly until the desired date and time of the
measurement are reached. The measurement
will then be displayed.
3. The display will shut o󰀨 automatically a few
seconds after the readings are displayed.
If there are no measurements stored in memory,
you will see dashes in the date and time elds
followed by a measurement of three 0s displayed vertically.
To clear the measurement history from memory, press and hold the
Memory button for at least ve seconds while the display screen is
showing only the time. Release the Memory button when you see the
M symbol in upper left hand corner of the display ash and disappears.
This indicates that the memory has been cleared.
NOTE: Stored measurements, time, date, and alarm settings will be lost if batteries become
low or are removed for more than 30 seconds.

E-18
What is an Irregular Heartbeat
An irregular heartbeat is dened as a hearbeat that varies from the
average of all heartbeats. When the monitor detects an irregular
rhythm during the measurements, the IHB indicator will appear on the
display with the measurement values.
Note: We recommend contacting your physician if you see this IHB indicator frequently.

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 o󰀩ce may cause
apprehension and can produce an elevated reading, 25 to 30 mmHg
higher than that measured at home. Home measurement reduces the
e󰀨ects 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
