Description of markings
※During the measurement process, do not use devices that generate
electromagnetic interference near this product, such as mobile phones,
as the strong radiation field generated by such devices will interfere with
the normal use of the product.
Otherwise, this product may cause mis-operation or inaccurate measurement.
※In the case of common arrhythmia (such as atrial premature beat,
ventricular premature beat and atrial fibrillation), the measurement will
cause errors.
※The main unit is not likely to cause interference to electronic devices
around (such as TV, computer, mobile phone)
※There may be a risk when the air cuff is in the state of persistent
hyperinflation. (causing discomfort such as blood stasis or paralysis in
the arm.) If such abnormality occurs, please remove the cuff.
※Be sure to use the parts provided by the manufacturer for replacement.
Otherwise, measurement errors may be caused.
Note: If the original parts are replaced by parts not provided by the
manufacturer, measurement errors may occur.

When replacing batteries, new batteries of the same type must
be used and all 4 batteries shall be replaced at the same time.
Please use the batteries within the expiration date.
Failure to comply with the above matters may result in injury
or damage due to battery heating, cracking or liquid leakage.
About batteries:
If the low battery mark ( ) appears on the display, please turn off the device
and replace all batteries.
Voice prompt (cantonese) "Low battery, please replace it"
Batteries last for approx. 300 times, which is 3 times/day for 3 months (when
using a pack of new Panasonic zinc carbon batteries). (Under the condition
that the room temperature is 23 °C, 22.7 kpa (170 mmHg) pressured, and the
circumference of upper arm is 30cm.)
If the ambient temperature is low, the battery life will be shortened.
The service life of other brands of batteries may be very short, so it is recommended
to use Panasonic zinc carbon or alkaline batteries.

Preparation Before measurement
For correct measurement, please read the following key points carefully,
and observe the exact environment and posture. Please refer to P3 (How
to take a proper measurement).
Measuring time
The blood pressure is constantly changing throughout the day.
Therefore, take the period with the least movement after getting up and
before sleeping as the measuring time.
It is closest to the blood pressure at night and basically with no
influence due to physical activities.
•Before breakfast
•Before taking medicine (in case of antihypertensive drugs, etc.)
•After urination
•Relax for 4~5 mins
The measured value is closest to the average blood pressure
in a day
•Relax for 4~5 mins
Prompt of measuring place and measuring time
Blood pressure is affected by climate, emotion, exercise, sleep time, food or
other conditions. In addition, blood pressure tends to rise because of blood
vessel contraction due to low outdoor temperature in winter.
Before sleep
Within 1 hour
after getting up
Within 1 hour
after getting up
No measurement
shall be taken in
case of the right
circumstances
Before sleep
•Outdoor and cold places
•After exercise or showering
•Within 1 hour after meals
•After drinking
•Shortly after drinking caffeinated
beverages or smoking
•When feeling restless
•When experiencing signs of urination
or defecation
Measure in a room with stable temperature, and in a non-anxious and calm
state, take five deep breaths and relax for 4~5 mins before measurement.
As the blood pressure is affected by various conditions, it is difficult to judge
whether or not the blood pressure value is true if only one measurement is
taken.
It is necessary to measure 2 to 3 times to confirm the change.

17
Preparation Before measurement
Posture Method of cuff wrapping
Height of cuff to heart
Do not lean forward
When the abdomen
is stressed, the blood
pressure will rise.
Do not talk
Talking will raise
blood pressure.
Keep your hands,
fingertips, arms
and body still
Subtle changes in blood
pressure cannot be detected.
So no proper measurement
can be taken.
Do not wrap the cuff
on your clothes
The pressure of the cuff
cannot be transmitted
to the blood vessels and
the blood pressure will rise.
Do not roll up the
shirtsleeve
The blood vessels in
the arm will be under
pressure and no proper
measurement can be taken.
Do not wrap the cuff
too loose
The pressure of the
cuff cannot be
transmitted to the
blood vessels and no
proper measurement
can be taken.
The height of 10 cm
will cause an error
of 7 mmHg.
•Please refer to P.3
for measurement in
correct posture
Do not touch the cuff
It will cause confusion
of measurement data.
So no proper
measurement can
be taken.
Do not compress the
tube
Once the tube is pressed
by the arm, it will cause
failure to take a proper
measurement.
Any blood pressure measurement will be influenced by the
posture of the user and his/her physical condition.

Preparation Wrapping the cuff
※Be sure to use a dedicated cuff
It can be wrapped on either left or right arm for measurement.
Take the measurement of left arm as an example.
The measurement results of the left and right arms may vary to
different extent due to different conditions of each user.
Therefore, please measure with the same arm every time.
1.
Wrap the cuff on your arm
2.
Wrapping position of
the cuff
When measuring by
the right arm
(1)Wrap the cuff (2~3) cm
above the elbow joint.
(2)The tube shall coincide
with the extension of
the middle finger.

If it is wrapped too loose, the cuff will swell and inflate, and
the blood vessel will be locally tightened, which will cause
an indication error, and the measured value will tend to rise
slightly.
If it is wrapped too tight, before air entering, the blood
vessel will be pressed by the cuff, so the measured value
will tend to decrease slightly.
