Using The Monitor
Selecting The Correct Cuff
Using the correct cuff size is important for an accurate reading. If the cuff is not the proper size, the reading may yield an incorrect blood pressure value.
The arm size is printed on each cuff.
The index and proper fit range, on the cuff, tell you if you are attaching the correct cuff. (Refer to "Attaching The Arm Cuff" below)
If the index points outside of the range, contact your local dealer to purchase a replacement cuff.

Using The Monitor
How To Take Proper Measurements
For the most accurate blood pressure measurement:
Sit comfortably at a table.
Rest your arm on the table.
Relax for about five to ten minutes before measurement.
Place the center of the cuff 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 for twenty or thirty minutes before taking the measurement.
Try to measure your blood pressure at the same time every day.
Measurement
During measurement, it is normal for the cuff to feel very tight. (Do not be alarmed).
After Measurement
After measurement, press the START button to turn off the power. Remove the cuff.
Note: The device has an automatic power shut-off function, which turns the power off automatically one minute after measurement.
Allow at least ten minutes between measurements on the same person.

Measurements
Model UA-851 is designed to detect the pulse and to inflate the cuff to a systolic pressure level automatically.
If your systolic pressure is expected to exceed 230 mmHg, read
"Measurement With The Desired Systolic Pressure" on the next page.

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 so that the center of the cuff will be at the same height as your heart. systolic pressure
Refer to the previous page for measurement
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 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 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. Refer to page 4 for the description of the symbols.
This blood pressure monitor 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.

What Is An Irregular Heartbeat
The device provides a blood pressure and pulse rate measurement even when an irregular heartbeat occurs. An irregular heartbeat is defined 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.

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 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 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
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 30 mmHg 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 more accurate, 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.
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
English 13
described in this manual to get to know your normal blood pressure. Regular readings give a more comprehensive blood pressure history. Be sure to note date and time when recording your blood pressure.
Consult your doctor to interpret your blood pressure data.
Troubleshooting
Nothing appears on the display, even when the power is turned on.
Batteries are drained.
Battery terminals are not in the correct position.
Replace all batteries with new ones.
Reinstall the batteries with negative and positive terminals matching those indicated on the battery compartment.
The cuff does not inflate.
Battery voltage is too low.
(LOW BATTERY mark) blinks. [ If the batteries are drained completely, the mark does not appear.]
The cuff is not fastened properly.
You moved your arm or body during the measurement.
Replace all batteries with new ones.
Fasten the cuff correctly.
The unit does not measure.
Readings are too high or too low.
The cuff position is not correct.
Make sure you remain very still and quiet during the measurement.
Sit comfortably and still.
Raise your hand so that the cuff is at the same level as your heart.
If you have a very weak or irregular heat beat, the device may have difficulty in determining your blood pressure.
The value is different from that measured at a clinic or doctor’s office.
Refer to “Why measure blood pressure at home”.
Other
Remove the batteries. Place them back properly and try the measurement again.
Note: If the actions described above do not solve the problem, contact the dealer. Do not attempt to open or repair this product, as any attempt to do so will make your warranty invalid.
English 14
Maintenance
Do not open the device. It uses delicate electrical components and an intricate air unit that could be damaged. If you cannot fix the problem using the troubleshooting instructions, request service from your dealer or from the A&D service group. The A&D service group will provide technical information, spare parts and units to authorized dealers.
The device was designed and manufactured for a long service life.
However it is generally recommended to have the monitor inspected every 2 years, to ensure proper functioning and accuracy. Please contact either your authorized dealer or A&D for maintenance.
