3. How to Take Proper Measurements
For best accuracy in blood pressure measurement:• Sit comfortably at a table. Rest your arm on the table.
• Relax for about 5 to 10 minutes before measurement.
• Raise your hand so that the cuff is at the same level as your heart.
• Remain still and keep quiet during measurement.
• Do not measure right after physical exercise or a bath.
We recommend you to rest 20 or 30 minutes before taking measurement.
• Measure your blood pressure at about the same time every day.

4. Measurement
During measurement, it is normal for the cuff to feel very tight. (Do not be alarmed.)

5. After Measurement
After measurement, press the START button to turn off the power.
Remove the cuff and record your data.
Note: The device is provided with an automatic power shut-off function which turns off the power automaticallyone minute after measurement.
Allow at least ten minutes between measurements on the same person.

7Measurements
Note: The UB-510, once used, will provide an inflation appropriate to the user, based on the previous measurement.

Normal Measurement
1. Sit comfortably with the cuff at the same level as your heartand relax.
2. Press the START button.
The average recorded blood pressures and data number aredisplayed briefly.
Then the display changes as indicated in the figure on theright as measurement begins.
The cuff starts to inflate. It is normal for the cuff to feel very tight.
Note: If you wish to stop inflation at any time, press the START
button again.
3. The measurement starts automatically when pressurizing
starts, and the(heart mark) blinks.
4. When measurement is complete, the systolic and diastolicpressure readings and pulse rate are displayed.
The cuff exhausts the remaining air and completely deflates
automatically.
5. Press the START button again to turn off the power.
Remove the cuff.
Note: The device is provided with an automatic power shut-offfunction.
Allow at least ten minutes between measurements on
the same person.
8Notes For Proper Measurement
Sit down in a comfortable position. Place the arm to be used for the measurement on a table or other support sothat the center of the cuff will be at the same height as your heart.
Relax for about five or ten minutes before taking a measurement. If you are excited or depressed by emotional
stress, the measurement will reflect this stress as a higher (or lower) than normal blood pressure reading and thepulse reading will usually be faster than normal.
An individual's blood pressure varies constantly, depending on what they are doing and what they have eaten.
What you drink can have a very strong and rapid effect 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 difficulty determining your blood pressure.
Should the device detect a condition that is abnormal, it will stop the measurement and display an error symbol.
See pages 3 and 4 for the description of symbols.
This blood pressure monitor is intended for use by adults only. Consult with your physician before using thisdevice on a child. A child should not use this device unattended.

Operation Mode
1. Normal measurement with storing data
(Refer to page 8)
Press the START button.
Blood pressure is measured and data is stored within the device.
The device can store the last thirty sets of data.
2. Recalling data
Press and hold the START button to recall the data.
Stored data are automatically displayed in order from the last data.
3. Clearing data
Remove batteries to clear all data. Re-install them again.
9What Is An Irregular Heartbeat?
Model UB-510 blood pressure monitor provides a blood pressure and pulse rate measurement even when anirregular heartbeat occurs. An irregular heartbeat is defined as a heartbeat that varies by 25% from the averageof 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 thisindicator frequently.

Pressure Bar Indicator

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 theheart contracts. Diastolic pressure occurs when the heart expands. Blood pressure is measured in millimeters ofmercury (mmHg). One's natural blood pressure is represented by the fundamental pressure, which is measured
first 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 undera doctor’s supervision.
11

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

Why Measure Blood Pressure At Home?
Blood pressure measured at a clinic or doctor's office may cause
apprehension and can produce an elevated reading, 25 to 30mmHg higher than that measured at home. Home measurement
reduces the effects of outside influences on blood pressure
readings, supplements the doctor's readings and provides a moreaccurate, complete blood pressure history.

WHO Blood Pressure Classification
Standards to assess high blood pressure, without regard to age,have been established by the World Health Organization (WHO),as shown in the chart on the right.

Blood Pressure Variations
An individual’s blood pressure varies greatly on a daily and seasonal basis. It mayvary by 30 to 50 mmHg due to various conditions during the day. In hypertensive
individuals variations are even more pronounced. Normally, the blood pressure riseswhile 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 describedin this manual to get to know your normal blood pressure. Regular readings givea more comprehensive blood pressure history. Be sure to note the date andtime when recording your blood pressure. Consult your doctor to interpret yourblood pressure data.
