CAUTION
This device is intended for adult use only.
This device is intended for no-invasive measuring and monitoring of arterial blood pressure.
It is not intended for use on extremities other than the arm or for functions other than
obtaining a blood pressure measurement.
Do not confuse self-monitoring with self-diagnosis. This unit allows you to monitor your
blood pressure.Do not begin or end medical treatment without asking a physician for
treatment advice.
If you are taking medication,consult your physician to determine the most appropriate time
to measure your blood pressure. Never change a prescribed medication without consulting
your Physician.
When the device was used to measure patients who have common arrhythmias such as
atrial or ventricular premature beats or atrial fibrillation, the best result may occur with
deviation. Please consult your physician about the result.
If the cuff pressure exceeds 40 kPa (300 mmHg), the unit will automatically deflate. Should
the cuff not deflate when pressures exceeds 40 kPa (300 mmHg), detach the cuff from the
arm and press the START/STOP button to stop inflation.
The equipment is not AP/APG equipment and not suitable for use in the presence of a
flammable anesthetic mixture with air of with oxygen or nitrous oxide.
The operator shall not touch output of batteries /adapter and the patient simultaneously.
To avoid measurement errors, please avoid the condition of strong electromagnetic field
radiated interference signal or electrical fast transient/burst signal.
The user must check that the equipment functions safely and see that it is in proper working
condition before being used.
This device is contraindicated for any female who may be suspected of, or is pregnant.
Besides providing inaccurate readings, the effects of this device on the fetus are unknown.
Manufacturer will make available on request circuit diagrams, component parts list etc.
This unit is not suitable for continuous monitoring during medical emergencies or operations.
Otherwise, the patient’s arm and fingers will become anaesthetic, swollen and even purple
due to a lack of blood.
Please use the device under the environment which was provided in the user manual.
Otherwise, the performance and lifetime of the device will be impacted and reduced.
During use, the patient will be in contact with the cuff. The materials of the cuff have been
tested and found to comply with requirements of ISO 10993-5:2009 and ISO
10993-10:2010. It will not cause any potential sensization or irritation reaction.
Please use ACCESSORIES and detachable partes specified/ authorised by MANUFACTURE. Otherwise, it may cause damage to the unit or danger to the user/patients.
The device doesn’t need to be calibrated within the two years of reliable service.
Please dispose of ACCESSORIES, detachable parts, and the ME EQUIPMENT according
to the local guidelines.
If you have any problems with this device, such as setting up, maintaining or using, please
contact the SERVICE PERSONNEL of Transtek. Don’t open or repair the device by
yourself.
Please report to Transtek if any unexpected operation or events occur.
Please use the soft cloth to clean the whole unit. Don’t use any abrasive or volatile cleaners.
Caution: These notes must be observed
to prevent any damage to the device

BEFORE YOU START BEFORE YOU START
Rest for 5 minutes before
measuring.
Wait at least 3 minutes between
measurements. This allows your
blood circulation to recover.
For a meaningful comparison,
try to measure under similar
conditions. For example, take daily
measurements at approximately
the same time, on the same arm,
or as directed by a physician.
Tie the Cuff
1.Tie the cuff on your upper arm,
then position the tube off-center
toward the inner side of arm in
line with the little finger.
2.The cuff should be snug but not
too tight. You should be able to
insert one finger between the
cuff and your arm.
3.Sit comfortably with your tested
arm resting on a flat surface.
2~3cm
4.Repeat steps 2 and 3 to set the [MONTH] and [DAY].

Maintenance
In order to get the best performance, please follow the
instructions below.
Put in a dry place and avoid the sunshine
Avoid intense shaking
and collisions
Using wet cloths to remove dirt
Avoid touching water,
clean it with a dry cloth in case.
Avoid dusty and unstable
temperature environment
Avoid washing the cuff
Only a physician can tell your normal BP range.
Please contact a physician if your measuring
result falls out of the range. Please note that only
a physician can tell whether your blood pressure
value has reached a dangerous point.
What are systolic pressure and diastolic pressure?
press
artery
vein
blood discharging
Systolic
relax
blood entering
Diastolic
When ventricles contract and pump blood out
of the heart, the blood pressure reaches its
maximum value in the cycle, which is called
systolic pressure. When the ventricles relax,
the blood pressure reaches its minimum value
in the cycle, which is called diastolic pressure.
What is the standard blood pressure classification?
The blood pressure classification published
by World Health Organization (WHO) and
International Society of Hypertension (ISH)
in 1999 is as follows:
Irregular Heartbeat Detector
CAUTION
The appearance of the IHB icon indicates that a pulse irregularity consistent with an
irregular heart-beat was detected during measurement. Usually this is NOT a cause for
concern. However, if the symbol appears often, we recommend you seek medical advice.
Please note that the device does not replace a cardiac examination, but serves to detect
pulse irregularities at an early stage.

An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is
measuring the systolic and diastolic blood pressure.During each measurement,
this equipment records the heartbeat intervals and works out the standard deviation.
If the calculated value is larger than or equal to 25%,the irregular heartbeat symbol
appears on the symbol when the measurement results are displayed.

ABOUT BLOOD PRESSUREINFORMATION FOR USER
This section includes a list of error messages and frequently
asked questions for problems you may encounter with your blood
pressure monitor. If the products not operating as you think it
should, check here before arranging for servicing.
Why does my blood

Why do I get a different

Readjust the cuff ,not too

measure again.
The monitor detected
motion,talking or the
pluse is too poor
while measuring.
Relax for a
moment and then
measure again.
1. Individual blood pressure varies
multiple times everyday. It is also affected
by the way you tie your cuff and your
measurement position, so please take the
measurement under the same conditions.
2.If the person takes medicine, the
pressure will vary more.
3.Wait at least 3 minutes for another
measurement.
The blood pressure is different even
throughout the day due to weather,
emotion, exercise etc, Also, there is the
“white coat” effect, which means blood
pressure usually increases in clinical
settings.
It is ok for both arms, but there
will be some different results for
different people. We suggest you
measure the same arm every time.
What you need to pay
attention to when you measure
your blood pressure at home:
If the cuff is tied properly.
If the cuff is too tight or too loose.
If the cuff is tied on the upper arm.
If you feel anxious.
Taking 2-3 deep breaths before
beginning will be better for measuring.
Advice: Relax yourself for 4-5
minutes until you calm down.
