1. General
This instruction manual is intended to assist the user in the safe and efficient
operation of the Be Better™ Premium Automatic Blood Pressure Monitor
model RX805. The device should be used in accordance with the procedures
described in this manual. It is important to read and understand the entire
manual, especially section 2 “Tips on Taking Blood Pressure Measurement.”
This device is intended for the non-invasive measurement of systolic and
diastolic arterial blood pressure and pulse rate in adults age 15 and above.
Principle Of Operation
This device uses oscillometric technology to measure the arterial blood
pressure and pulse rate. The cuff is wrapped around the arm and automatically
inflated by the air pump. The sensor in the device senses weak fluctuation of
the pressure in the cuff produced by extension and contraction of the artery of
the arm in response to each heartbeat. The amplitude of the pressure waves is
measured, converted in millimeters of the mercury column, and is displayed on
the display.
This device can not provide reasonable accuracy if used or stored in
the temperature or humidity beyond the range stated in the section
“TECHNICAL SPECIFICATIONS” of this manual.
2. Tips On Taking Blood Pressure Measurement
2.1 About Blood Pressure
Blood pressure level is determined in the circulatory center of your brain. Your
nervous system allows the body to adapt or alter blood pressure in response to
different situations. Your body alters your pulse or heart rate and the width of
blood vessels through changes in muscles in the walls of blood vessels.
Your blood pressure reading is highest when your heart pumps or ejects blood.
This stage is called your systolic blood pressure.
Your blood pressure is lowest when the heart rests (in-between beats). This is
called your diastolic blood pressure.
It is critical to maintain blood pressure values within a “normal” range in
order to prevent cardiovascular diseases. Increased blood pressure values
(various forms of hypertension) have associated long and medium term health
risks. These risks concern the arterial blood vessels of your body, which
are endangered due to constriction caused by deposits in the vessel walls
(arteriosclerosis). An insufficient supply of blood to important organs (heart,
brain, muscles) can be the result. Furthermore, with long-term increased blood
pressure values, the heart will become structurally damaged.
There are many different causes of the appearance of high blood pressure. We
differentiate between common primary (essential) hypertension, and secondary
hypertension. The latter group can be ascribed to specific organic malfunctions.
Please consult your doctor for information about the possible origins of your
own increased blood pressure values.
2.2 Normal Blood Pressure Values
Blood pressure is generally considered too high when, at rest, the diastolic
pressure is above 90 mmHg or the systolic blood pressure is over 140 mmHg.
If you obtain readings in this range, consult your doctor immediately. High blood
pressure values over time can damage blood vessels, vital organs such as the
kidney, and your heart.
Should the systolic blood pressure values lie between 140 mmHg and 160
mmHg or the diastolic blood pressure values lie between 90 mmHg and 95
mmHg, consult your doctor. Regular self-checks will be necessary.
With blood pressure values that are too low (i.e., systolic values under 105
mmHg or diastolic values under 60 mmHg), consult with your doctor.
Even with normal blood pressure values, a regular self-check with your blood
pressure monitor is recommended. In this way you can detect possible changes
in your values early and react appropriately.
Refer to the following table for classifying blood pressure values (units: mmHg)
according to the World Health Organization (WHO):

2.3 Obtaining Accurate Measurements
Your blood pressure can vary based on numerous factors, physiological
conditions, and your surroundings. Follow these guidelines to obtain accurate
and error-free measurements of your blood pressure and pulse rate.
2.4 Before Measuring
• Avoid eating, smoking as well as all forms of exertion directly before the
measurement. All these factors influence the measurement result. Relax by
sitting in an armchair in a quiet atmosphere for about 5 minutes before the
measurement.
• Always take measurements on the same arm (normally left) and in the
same posture. Do not switch between right and left arms while recording
your blood pressure as there may be a difference of up to 10 mmHg
pressure between the two arms.
• Attempt to carry out the measurements regularly at the same time of day,
since blood pressure changes during the course of the day. The ideal time
to measure your blood pressure is in the morning after you wake up, before
breakfast and physical activity, and in the absence of the urge to urinate.
• Rest for 5 minutes sitting quietly and release all the tension in your body
— especially the arm muscles — before beginning with the measurement.
Remain calm and quiet when the measurement is in process. Do not speak
or move your arm (as well as other body) muscles during the process.
2.5 Common Sources of Error
Any efforts by the patient to support the arm can increase the blood pressure.
Make sure you are in a comfortable, relaxed position and do not activate any of
the muscles in the measurement arm during the measurement. Use a cushion
for support if necessary and rest your arm completely.
ATTENTION!
Comparable blood pressure measurements always require the same
conditions with a peaceful and calm environment. Ensure that you
take measurements under the same conditions to obtain an accurate
estimate of blood pressure variation patterns.
• The cuff should be at heart level.
• If the arm artery lies considerably lower or higher than the heart, an
erroneous value of blood pressure is measured. Each 15 cm difference in
height results in a measurement error of 10 mmHg.
• A loose cuff causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can
lead to false results. Consecutive blood pressure measurements should be
repeated after at least a 15 second pause or after the arm has been held
up in order to allow the accumulated blood to flow away.
2.6 Fitting the Cuff
a)Put the end of the cuff (with fastener) through
the metal ring, making the cuff a cylinder.
(Ignore this step if your cuff is already set up.)
Proper assembly allows the Velcro® to match up
properly.
b)Place the cuff around your arm. Make sure the
bottom edge of the cuff is about 1” above the
elbow joint. Adjust the cuff so that the rubber
tubing under the cuff lies over the brachial
a)
b)
artery, which runs on the inside of the arm (see Fig. C).
c)
c)Pull the cuff and tighten it by attaching the
Velcro® fastener. Normally, the left arm is used,
unless there is a physical reason for using the
right arm.
d)The cuff should fit snugly around the arm, but
not too tight. You should be able to fit two
fingers under the cuff.
e)Place the arm on the table (palm facing upwards)
so that the cuff is at the same level as the heart.
Make sure there is no kink in the hose.
d)
e)
f)You can adjust the level of your arm by putting a
cushion under your arm.
f)
g)Remain seated in a comfortable room
temperature for at least 5 minutes, then
start the measurement.
g)
h)For those who cannot put the cuff on the left
arm, put it on the right arm as shown.
i) Consecutive measurements will cause blood
accumulation in the lower arm which will affect
the measuring results. To improve reading
accuracy, raise the arm being measured,
squeeze and relax your hand several times, then
take another measurement. Another option is
to take the cuff off and wait at least 10 minutes
before repeating measurement.
h)
i)
j) If this device was stored in low temperature, it is
necessary to leave it in room temperature for at
least 1 hour, otherwise the measurement can be
inaccurate.
ATTENTION: Do not use cuff other than the original cuff contained in this kit!

5. Setting the Date and Time
The function provides accurate measuring time for each measurement. To get
accurate date and time, the user should preset the date and time correctly before
the first use of this device. The operation procedure for presetting Date/Time is as
follows:
1.When the device is connected to power on for the first time, the
display will show as Fig. 1.
2.Press and hold button ‘M1’, then press button ‘O/I’, and the year
number flashes.
3.Press button ‘M1’ or ‘M2’ to subtract or add the number, and
press button ‘O/I’ for confirmation.
4.When the year setup is finished, the month number will flash
automatically. Please follow the same instruction as above to set
month, date and time.
5.Press button ‘O/I’ to finish setup. If you want to change the date and time,
please repeat procedure 2, 3, 4.
Note: When in the Date/Time setting, if no button is pressed in 1 minute, the
device will automatically return to standby mode.
6. Measuring Your Blood Pressure
1.Insert the tube plug into the air connector. Before the measurement, take 3~5
times deep breaths and relax yourself. Don’t talk or move your arm.
2.Press button ‘O/I’, and all symbols will appear on display for 2 seconds as Fig.4.
Then two short beeps will sound and ‘0’ will appear on the screen. Pump begins
to inflate with display showing the reading of pressure. Generally the pressure
will reach 190 mmHg as Fig.5.
3.The pump will stop inflating and pressure begins to decrease gradually, during
which the user’s blood pressure and pulse will be calculated as Fig.6.
4.There will be a long beep following the accomplishment of measurement. The
air in the cuff will deflate quickly and the blood pressure reading and pulse
reading will show in the display. Moreover the measuring time will also display
together in two screens alternately. At the same time, the ‘M1’ or ‘M2’ will flash
to remind the user to record the reading as Fig.7.
5.Press button ‘M1’ or button ‘M2’ to record the reading in corresponding memory.
For example, if button ‘M2’ is pressed, the display will show as Fig.8. If the user
does not press button ‘M1’ or ‘M2’ or press button O/I, the reading won’t be
recorded.
6.Press the button ‘O/I’ to return to the standby mode. Please rest for at least 3
minutes for another measurement. If the device isn’t used for 3 minutes, the
device will return to standby mode automatically.
Automatic Inflation
There are 4 given levels of given inflation pressure for this device: 190mmHg,
230mmHg, 270mmHg and 300mmHg. When 190mmHg is not enough or
movement of arm occurs, the device will automatically inflate to a reasonable
pressure level to ensure a successful measurement. It is not a fault.
Rapid Deflation During Measurement
If you do not feel well during measurement or want to stop the measurement for
some reason, you can press the O/I button. The device will quickly release the
air in cuff and the device will be returned to standby mode.
Repeated measurements with intervals of 3 minutes are recommended, so you
can calculate the average to get more accurate measurement. Atherosclerosis
patients are required longer intervals (10-15 minutes) as elasticity of patients’
vessels decreased significantly in these diseases. 10-15 minute intervals is also
applicable for patients suffering from diabetes for a long time.
7. Function of Memory
Memory Recall
1.RX805 can store 60 sets of readings each in ‘M1’ and ‘M2’, and will
automatically calculate the average value of the latest 3 readings for ‘M1’ and
‘M2’ respectively. When the memory is full (60 sets of readings are stored), the
oldest reading will be replaced by a new one. Memory will not clear away even
if power supply is removed.
2.After a measurement is finished or when the device is in standby mode, the user
can press button ‘M1’ or button ‘M2’ to recall memory. Press button ‘M1’, the
display will show the average value of the last 3 readings taken as Fig.9.
3.Press again, the display will show ‘01’, which means the last reading taken, then
turns to another screen to show readings and measuring time as Fig.10;
4.Press again, the display will show ‘02’, which means the second to the last
reading taken.
Memory Clearance
After a measurement is finished or when the device is in standby
mode, press and hold button ‘M1’ or ‘M2’ for at least 5 seconds, the
display will show ‘Clr’ which means the stored readings for ‘M1’ or
‘M2’ have been removed. Fig. 11.
8. Blood Pressure Assessment Software
Standards for assessment of high or
low blood pressure, regardless of age,
have been established by World Health
Organization (WHO) as shown in the
chart to the right:
The indicator displays a segment, based on the current data, corresponding
to the WHO classification. For example, if your blood pressure is 135 mmHg
(Systolic Pressure), 78 mmHg (Diastolic Pressure), according to the world health
organization standard, your blood pressure level is High Normal.
Note:
1.If the systolic blood pressure and diastolic blood pressure fall into different
categories, the higher value should be taken for classification.
2.The WHO blood pressure classification indication in the device is only a
reminder, it can not be regarded as the final diagnosis.
9. Irregular Heartbeat Detector
Model RX805 blood pressure monitor provides a blood pressure and pulse rate
measurement even when an irregular heartbeat occurs. When the device detects
an irregular heartbeat, or any excessive body movement during the measurement,
the
icon will appear and flash. It is important that you be relaxed, remain still
and do not talk during measurement. If the
symbol appears frequently (e.g.
several times a week), it may be an idication of a more serious heart problem,
and you should consult your doctor.
