Installing / Changing the Batteries
Slide the battery cover as shown to remove it
from the device.
Insert two AAA / LR03 size batteries in the battery
compartment, with positive (+) and negative (-)
terminals matching those indicated on the battery
compartment.
Slide the battery cover back on the device.
Use only AAA/LR03 batteries.
Fastening the Cu
Wrap the cu around your wrist about 1 cm above your hand as shown in
the gure at the right.
The monitor should be placed on inner side of the arm.
Fasten the cu
tightly using the
Velcro strip.
Note: For proper
measurements,
fasten the cu tightly
and measure on a
bare wrist.

Measurements
Sit comfortably in a chair with
your feet at on the oor. Place
your left arm on a table at a slight
angle.
1
Raise your hand so that the cu is
at the same level as your heart.
Press the START button. The
average recorded blood pressures
and data number are displayed
briey. Then the measurement
begins. The cu starts to inate. It
is normal for the cu to feel very
tight. Note: If you wish to stop
ination at any time, press the
START button again.
When measurement is complete,
the systolic and diastolic pressure
readings and pulse rate are
displayed. The cu exhausts the
remaining air and completely
deates automatically.
After the measurement:
Press the start button to turn o the device. The device is provided with an
automatic power shut-o function.

How to Take Proper Measurements
For the most accurate blood pressure measurement:
Sit down in a comfortable position. Place the arm to be used for the measure-
ment on a table or other support so that the center of the cu will be at the
same height as your heart.
Relax before taking a measurement. If you are excited or depressed by
emotional stress, the measurement will reect 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 eect on your blood pressure.
This device bases its measurements on the heartbeat. If you have a very weak or
irregular heartbeat, the device may have diculty determining your blood
pressure.
Should the device detect a condition that is abnormal, it will stop the
measurement and display an error symbol. Refer to page 4 for the description of
the symbols.
This device is intended for use by adults only. Consult with your physician before
using this device on a child. A child should not use this device unattended.
Place the center of the cu at the same height as your heart.
Remain still and keep quiet during measurement.
Do not measure right after physical exercise or a bath. Rest before taking the
measurement.
Try to measure your blood pressure at the same time every day.
Insert the batteries as shown in the battery compartment. If not, the device will
not work.
When (LOW BATTERY mark) blinks on the display, replace all batteries
with new ones. Do not mix old and new batteries. It may shorten the battery life,
or cause the device to malfunction.
(LOW BATTERY mark) does not appear when the batteries are drained.
Battery life varies with the ambient temperature and may be shorter at low
temperatures.
Use the specied batteries only. The batteries provided with the device are for
testing monitor performance and may have a limited life.
Remove the batteries if the device is not to be used for a long time. The batteries
may leak and cause a malfunction.
The stored data are cleared when the batteries are removed.

About Memory
The device automatically stores up to thirty blood pressure and pulse measurements in memory. Data stored in memory are assigned a data number in the order
of the newest to the oldest. The oldest data displays as "n01". The M symbol in the
upper left corner of the display indicates that you are viewing previous data stored
in memory.

measurement and the data are displayed.
The data are automatically displayed in turn.
The display will shut o automatically after all
data is displayed.
Clearing Data
Remove the batteries to clear all data.
Re-install them again.
If there is no data stored in memory, you will see two 0s displayed vertically
followed by a blinking "A00".

What is an irregular heartbeat
Sendo Advance provides a blood pressure and pulse rate measurement even
when an irregular heartbeat occurs. An irregular heartbeat is dened as a
heartbeat that varies by 25% from the average of all heartbeats during the blood
pressure measurement. It is important that you be relaxed, remain still and do not
talk during measurements.
Note: We recommend contacting your physician if you see this
indicator frequently.
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:
Do not smoke
Exercise regularly
Reduce salt and fat intake
Have regular physical checkups
Maintain proper weight
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.
Consult your doctor to interpret your blood pressure data.
