Measurement
Sit comfortably in a chair with your feet at on the oor. Place your left arm on a table at a slight angle.
1
Place the cu on the arm (preferably the left arm). The cu must be at the level with the heart.
3
Wrap the cu around the upper arm, about 2 - 3 cm above the elbow, as shown.
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.
Conrm that the index points within the proper t range.

Pres the START button.
The average blood pressures and last data number are displayed briey. When is ashing and the mark , is displayed the device is ready for measurement.
Note: If the mark , is displayed , the cu has air trapped in it. Press the exhaust valve button until the mark is displayed.
Pressurize the cu by squeezing the rubber bulb . Stop squeezing the bulb when the mark disappears.
The deation starts automatically. The heart mark starts blinking, indicating that the measurement is in progress.
Note: When the measurement is made with insucient pressure, the mark will be displayed.

When the measurement is complete, the buzzer sounds and the mark is displayed. The systolic and diastolic pressure readings and pulse rate are displayed and stored.
Press the exhaust valve button to completely release air from the cu.
Press the START button to turn the power o.
Automatic power-o function: If the device is left on after a measurement, it will turn o automatically after about one minute.
If a subsequent measurementuired, turn o the power and turn it on again. When is displayed, the device is ready for another measurement.

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 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.
This device bases its measurements on the heartbeat. If you have a very weak or
irregular heartbeat, the device may have diculty 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 specied 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.
CAUTION

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.
Recalling Data
When nothing is displayed, press and hold the START button to display the data number. The data number of the most recent measurement and the data are displayed.
The data are automatically displayed in turn.
The display will shut o automatically after all data is displayed.
Note: If you press the START button while recalling data, the device starts measurement.
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".

Selecting The Correct Cu
Using the correct cu size is important for an accurate reading. If the cu is not the proper size, the reading may yield an incorrect blood pressure value. The arm size is printed on each cu. The index and proper t range, on the cu, tell you if you are attaching the correct cu. (Refer to "Attaching The Arm Cu" below.) If the index points outside of the range, contact your local dealer to purchase a replacement cu
What is an irregular heartbeat
Sendo Economy provides a blood pressure and pulse rate measurement even when an irregular heartbeat occurs. An irregular heartbeat is dened 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.
