ABOUT BLOOD PRESSURE
What is blood pressure?
Blood pressure is the force generated by the blood against
the walls of arteries during cardiac contraction and relaxation
(e.g., the pumping action of the heart).
What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood out of the heart,
blood pressure reaches its maximum value. This highest
pressure in the cycle is known as systolic pressure. When the
heart relaxes between heartbeats, the lowest blood pressure
is diastolic pressure.
What is mean arterial pressure (MAP)?
The mean arterial pressure (MAP) is the average pressure
that forces blood through the arteries. It is not the average of
the systolic and diastolic blood pressure; rather, MAP
corresponds to a state of balance between the compressive
and expansive forces acting on the arterial wall when there is
no distension outward or inward. MAP is an excellent way to
evaluate the stress on the walls of your blood vessels, and
can be used to evaluate excessive load on the cardiovascular
system. Show your MAP history to your doctor to provide
additional information that may help him or her understand
your situation.
Why measure your blood pressure?
Blood pressure measurement can highly reflect one’s health
condition. High blood pressure is potentially linked to serious
illnesses such as stroke, heart disease and kidney failure.
Since there is no symptom most of the time, many hypertensive
Page 5

GB
people do not realize they are at risk until their health is
seriously threatened.
What is the standard blood pressure classification?
The following chart (Figure 3) was taken from the World Health
Organization (WHO), and describes the various classifications.
Please note:
· Hypotension value is for reference only.
· Blood pressure is considered high when either the diastolic
or systolic blood pressure value exceeds the normal range.
· Only a physician can tell you your normal blood pressure
range and the point at which you are at risk. Consult your
physician to obtain these values. If the measurements taken
with this product fall outside the range, consult your physician.
Why does my blood pressure fluctuate throughout the day?
Individual blood pressure varies greatly both on a daily and a
seasonal or temperature basis. These variations may be more
pronounced in hypertensive patients. Normally the blood
pressure rises while at work and is at its lowest during sleep.
Figure 4 below illustrates the variations over a single day with
measurement taken every five minutes. The thick line
represents sleep time. The rises in blood pressure at 4 PM (A
in the graph) and 12AM (B in the graph) correspond to an
attack of pain and sexual intercourse (Beven, Honour &
Stott, Clin. Sci. 36:329, 1969).
HOW DOES THE BLOOD PRESSURE
MONITOR WORK?
This product uses the Oscillometric Measuring method to detect
your blood pressure. Before every measurement, the main unit
establishes a “zero pressure” equivalent to the air pressure.
Then it starts inflating the wrist cuff to 180mmHg or higher until
it senses that it has block ed your b lood in the artery . After that,
the deflation process starts, during which time the main unit

detects pressure oscillations generated by beat-to-beat
pulsatile, which is used to determine the systolic, mean and
diastolic pressure, and also your pulse rate. Any motion during this
period will result in an incorrect measurement. After all readings are
determined and displayed on LCD, the measurement is finished
and the wrist cuff automatically deflates.

3. Replace the cover (Figure 5c).
AAA
AAA
Note: Replace the batteries whenever the weak battery
mark (
) shows, the display is dim, or the display does
not illuminate when the power is on. Replace all the
batteries at the same time – it is dangerous to mix old
and new batteries.
Contact your local waste disposal authority for
instructions on how to dispose of used batteries. Used
batteries can be harmful to the environment, and should
not be thrown out with household trash.
Setting the date, time, and measurement unit
It is important to set the clock before using your blood pressure
monitor, so that a time stamp can be assigned to each record
that is stored in the memory.
T o set the date, time, and measurement unit:
1. Press and hold SET for 2 seconds to enter the setting
mode.
The setting order is as follows: 12/24 hour format, hour,
minute, month/day or day/month format, month, date,
and measurement unit (mmHg or kPa).
2. Press
to increase a value or change the setting.
3. Press SET to accept the change and switch to the next
setting.
4. When you are finished, press ON to exit the setup
menu.

Positioning the wrist cuff
It is important to properly position the wrist cuff to ensure that you receive an accurate reading.
1. Remove all accessories (watch, bracelet, etc.) from your left wrist. If your physician has diagnosed you with poor
circulation in your left arm, use your right wrist.
2. Roll or push up your sleeve to expose the skin.
3. Apply the cuff to your left wrist with your palm facing up (Figure 6a).
4. Position the edge of the cuff about 1 centimeter from the bottom of your palm (Figure 6b).
5. Fasten the wrist cuff around your wrist, leaving no extra room between the cuff and your skin. If the cuff is too loose, the
measurement will be inaccurate (Figures 6c – 6d).

TAKING A BLOOD PRESSURE
MEASUREMENT
You can choose to take your blood pressure while sitting or
lying down.
Helpful Tips for taking a measurement:
· Be sure to set the clock before taking your first
measurement, or whenever you replace the batteries,
so that the date and time are stored in the memory
with your history. For instructions, refer to page 6.
· It is important to relax when taking your blood pressure.
Try to take a 15-minute rest before you begin.
· Do not lean backward or bend your wrist inward while
taking a measurement.
· Avoid talking or moving your fingers and hand while
taking a measurement. Rapid movements or other
activities may alter your reading.
· Wait at least one hour before taking your blood pressure
if you have just eaten a large meal.
· Do not smoke or drink alcohol before taking your blood
pressure.
· Do not measure your blood pressure if you are under
stress.
· Wait at least 3 minutes between measurements. This
allows your blood circulation to recover.
· For a meaningful comparison, try to measure under
similar conditions. For example, take daily
measurements at approximately the same time, on the
same wrist, or as directed by a physician.
· To stop the measurement process at any time, press
the ON button.
. The main unit automatically switches off 1 minute after
taking a measurement.
. To save the battery life, press the ON button as soon
as you are finished.

– sitting or lying down.
2. Position your body so that your wrist is parallel with your
heart, using the chart and illustrations below as a guide.
IF you are… THEN…
Place your elbow on a table, using the
plastic storage case or other object as a
support under your forearm. Your wrist
should be parallel with your heart with the
palm facing up.

3. Relax your hand.
4. Press the ON button.
Result: After a few seconds, the blood pressure monitor
beeps and begins inflating the wrist cuff. It then slowly
deflates until there is another beep, signifying that the
measurement is complete. Don’t move from the first beep
until the last to ensure a more accurate measurement.
Your systolic and diastolic pressure readings flash on
the display, followed by MAP (Mean Arterial Pressure,
see page 4) and pulse per minute readings every two
seconds. The measurement is automatically stored as
the first (1) entry in the memory; the last entry (60) is
dropped, and all the entries in between move up one digit
(e.g., 58 becomes 59, and so on).
RECALLING MEASUREMENTS STORED IN
THE MEMOR Y
Up to 60 measurement records can be stored in the memory . The
records are automatically stored each time you take a new
measurement. To view a history of your measurements, press
