Setting up your Blood Pressure Monitor
It is recommended that you rest for at least 5 minutes before taking your blood pressure
measurement. Allow at least 3 minutes rest between measurements to allow the blood
circulation in your arm to recover. The Blood Pressure Monitor is designed for use by adults
and should not be used on infants or young children.
We recommend that you carry out your test whilst sitting at a table with both of your feet flat
on the floor, do not cross your legs. Ensure that the cuff is at the same height as your heart as
this will place the monitor and your arm in an ideal position for the best results.
Place the cuff on your selected arm (please refer to ‘Your first test’ on how to select an arm).
Ensure the cuff is secure. Do not inflate the cuff when it is not wrapped around the upper arm.
Avoid compression or restriction of the rubber tubule during measurement as this may cause
an inflation error due to continuos cuff pressure. If this occurs, switch the unit off immediately
by pressing the START button.
Do not move your arm, body or the monitor and do not move the rubber tubule during
measurement and do not talk.
Setting the time and date
Press the START and MEM buttons simultaneously, the monitor will beep and the month will
flash. Press MEM repeatedly to select the month, press START to confirm. Follow the same
process to select the date and time (hours and minutes).

Putting on the cuff:
1. Place the cuff 1~2cm above the elbow joint. Measuring can be
done on light clothing such as a shirt or blouse. However, if you
have a weak pulse, it is recommended you test on a bare arm.
Remove any tight or restrictive clothing from your arm.
For example, restriction caused by rolling up a shirt sleeve.
2. Place hand on a flat surface with the palm facing up and with the
rubber tubule running down the centre of the arm.
3. Turn the cuff end outwards and tighten it by pulling it through the
metal loop and pressing the hook surface of the cuff on to the
loop surface of the cuff. To get the correct tightness, you should be
able to fit two fingers under the cuff.
4. Use your free hand to adjust the tightness of the cuff until it
is firm.
The cuff can be cleaned by hand with warm, soapy water. Rinse thoroughly with cold
water and towel dry. PLEASE DO NOT IRON.
ONLY USE THE CUFF SUPPLIED WITH THIS MONITOR. If a larger size is required you can
purchase an extra large cuff from www.betterlife.co.uk
Setting up your Blood Pressure Monitor Setting up your Blood Pressure Monitor
Your first test
We recommend that for your first test you test both your arms. This will determine which arm
should be used for future measurements. Take note of your systolic (higher number) reading
on both arms. The arm which gives the higher systolic reading should be used in the future for
testing.
Note: Ensure you do not suffer from any medical conditions which
will prevent you from having your blood pressure measured in both arms.
Example:
Left arm: 132 (systolic)
86 (diastolic)
Right arm: 128 (systolic)
84 (diastolic)
Reading your results
The example above shows that you should use your left arm in future testing as it has the
highest systolic reading.

Measuring Process
a. Once the cuff has automatically inflated, the LCD screen will display a flashing heart whilst
the pressure is gradually reduced and the monitor takes an automatic measurement
b. The monitor will faintly beep when the automatic measurement has finished. It is advised
to use the monitor in a quiet room in order to hear the beep. The reading will be
displayed on the screen along with the pulse rate.
• If the reading displays this shows that the monitor has detected an irregular
heartbeat which will be caused by common arrhythmias. This will result in an
inaccurate reading. It is advisable to restart again after a short time delay.
If it occurs again it is advisable to check with your doctor to obtain an accurate assessment.
• If there is an error or abnormal reading, please refer to the Abnormality & Troubleshooting
section.
c. During measurement, you can press the “START” button to turn off the monitor manually.
Memory
Press MEM button in time mode to select the memory function, the LCD will display the
average value of the last three results.
By pressing the MEM button again the most recent result will be displayed. The memory can
store 2 x 60 sets of measurements, which also include the date and time of the reading. The
results will be automatically stored. In memory mode, press START to switch the U1 or U2,
then press MEM to confirm. U1 or U2 will be displayed depending on which memory store
you are using.
Press MEM continuously to display the previously stored measurements one by one. Once the
memory has been filled with 60 sets of data, the 61st measurement when taken will be stored
as the most recent reading whilst the first reading you took will be automatically deleted.
You can delete stored memory readings by pressing MEM for 3 seconds, and all results in the
memory will be deleted and you will hear 3 consecutive beeps.

Using your Blood Pressure Monitor Using your Blood Pressure Monitor
What the results mean
a. The LCD screen will automatically display the systolic and
diastolic pressure reading in mmHg and the pulse rate in
pulse/min after each measurement.
b. Record date, time, systolic reading, diastolic reading and pulse
rate on your record table which you will find in the back of the user manual (including
anything which may have influenced your blood pressure reading e.g. stress, anxiety). This
will help you monitor trends. Please take this record card with you on your visits to your
doctor, pharmacist or healthcare professional.
NOTE: Measurements should ideally be taken at the same time, under the same
conditions and in the same position each time
Please be aware that blood pressure can fluctuate since it responds to minute changes in the
body. It is unusual to continuously remain at the same value, hence it is recommended that
the blood pressure be determined based on an average of multiple measurements. If you
experience a higher than normal reading, do not panic as this can happen. Relax and take a
break for at least 10 minutes before measuring your blood pressure again. Low blood
pressure (Hypotension) and high blood pressure (Hypertension) can only be diagnosed by
a qualified healthcare professional, such as a doctor or pharmacist. If you have any
concerns or questions, please contact your local pharmacist or healthcare professional.
To get an accurate value:
• Measure at least one hour after eating and
avoid measuring immediately after bathing
• Measure one hour after smoking or drinking
alcohol/coffee
• Relax for 5 minutes before taking a measurement
and remain relaxed whilst measuring
• Do not move or talk during measurement, as this will affect the accuracy
• If you suffer from atrial or ventricular premature beats or atrial fibrillation you may get an
inaccurate reading.
Re-measuring
If you want to measure again, press “start” button to switch off and press “start” button again.
• Leave at least three minutes between measurements to allow blood circulation to the arm
to return to normal
• Do not measure your blood pressure too many times in one session as it may cause
discomfort in the arm
• If you feel any discomfort or pain, turn the monitor off and remove the cuff immediately
• The unit will return to standby mode, displaying the day and month, after 1 minute if
not being used

Your heart is just like a pump which works all the time to make the blood flow through all
blood vessels.
Blood pressure measures the force on the wall of the blood vessels caused by the pressure of
the blood.
The output of blood from the heart when it pushes blood around the body is called systolic
blood pressure. Diastolic blood pressure is the measurement of the blood returning to the
heart.
Blood pressure is normally written as, for example:
120 (systolic)
80 (diastolic)
Fluctuation of Blood Pressure
Blood pressure fluctuates constantly during the day. Its value in
the day time is higher than in the evening with the lowest level
being at midnight. The pressure begins to rise again at 03:00am
and reaches its highest level any time during the day – so it is
impossible to get a consistent reading. For this reason, please take
your measurements at the same time of day.

* If systolic and diastolic BP fall into different categories, the higher value should be taken for classification e.g. if your BP is
141/83 you should read the advice in the Hypertension category (not the normal category). Your BP should be re-assessed
professionally at least once every 5 years unless you have high BP in which case it should be re-assessed at least once a
year - speak to your pharmacist or healthcare professional.
