1. Identification For use
Truly Automatic Arm Blood Pressure Monitor intended to measure the systolic and
diastolic blood pressure and pulse rate of an adult individual by using a non-invasive
technique in which an inflatable cuff is wrapped around the upper arm.
The devices’ features include irregular pulse rhythm detection during measurement, and
will display a alert signal with the reading when irregular heartbeat is detected.
The devices’ feature include Bluetooth function to transmit data to an external Bluetooth
device with wireless communication .
The devices are intended to use of Over-The-Counter
2. Safety Precautions
Caution
The monitor uses the oscillometric method to measure systolic and diastolic blood
pressure, as well as heart rate 。
- This device is intended for use in measuring blood pressure and pulse rate in the
adult population, do not use this device on infants or persons who cannot express
their intentions: The monitor is not intended to be a diagnostic device, It is a home
healthcare product only and it is not intended to serve as a substitute for the advice of
a physician or medical professional。
- Don't not use this device for diagnosis or treatment of any health problem or disease,
Measurement results are for reference only, consult a healthcare professional for
interpretation of pressure measurements, Contact your physician if you have or
suspect any medical problem. Do not change your medications without the advice of
your physician or healthcare professional。
- Use only Truly authorized parts and accessories Parts and accessories not approved
for use with the device may damage the unit and get a error of measurement。There
are no replaceable parts (such as sensors, electrode pads, etc.). Do not disassemble
or repair or modify the ME EQUIPMENT, it will get a error of measurement If you need
to repair, please contact the dealer and repair it.
- Proper cuff size is critical for accurate measurements ，Follow the instructions in this
manual and printed on the arm cuff to ensure the appropriate size of cuff is being
used。
- Blood pressure measurement can be affected by the other factors; Position of the
user such as bending over the body or cross-legged sitting will produce abdominal
pressure or make the position of the arm below the heart, that will increase the blood
pressure。
This product is not suitable for people with arrhythmias or serious arteriosclerosis.
It may have difficulty determining the proper blood pressure for pregnant women
and for users with irregular heartbeat, diabetes, pre-eclampsia, poor circulation of
blood, measurement on the arm on the side of a mastectomy,kidney problems or
for users who have suffered from a stroke；
- When measurement, The pressurization of the cuff to arm where intravascular access
or the rapy,or an arterio-venous(A-V) shunt,is present because of temporary
interference to blood flow and could result in injury to the patient；

4/15

- When measurement, The pressurization of the cuff can temporarily cause function of
simultaneously used monitoring other device on the same limb；
- The pulse display is not suitable for checking the frequency of heart pacemakers；
- Do not use a cellular phone near the device, It may result In an operational failure；
- Do not use the monitor in the driving or flying vehicles；
- Frequenly measuring will make the blood not flow, cause the arm-numbness and
abnormal reaction of body。
When you are using the monitor to measure especially frequently used, the arm is
compressed by the cuff, and then the fingertip will be caused congestion. During the
congestion, please loosen the cuff and lift the hands over your head, and make your right
and left hand squeese and stretch 15 times, them will unclog the congestion；
Do not applying the CUFF over a wound, as this can cause further injury；
- When measurement, please check that operation of the device does not result in
prolonged impairment of the circulation of the blood of the patient；
- Do not compress the cuff tube during the measurement, or it will cause fail inflation or
affect the result of measurement；
- Please use the product in the approved operate environment, the time required for the
ME EQUIPMENT to warm from the minimum storage temperature is two hours；the
time required for the ME EQUIPMENT to cool from the maximum storage temperature
is two hours；or will cause the inaccurate result of Handling batteries properly:
measurement；
- Handling batteries properly: measurement
As soon as old batteries run out, replace with newbatteries,
Do not use old and new batteries together
Align the polarities of batteries correctly;
When the unit will not be used for more than 3 months,remove the
batteries,Ohterwise, batteries may leak and cause damage to the unit。
- Dispose of the device,components and optional ,accessories according to applicable
local regulation,Unlawful disposal may cause environmental pollution。
- Don’t calling around the Blood pressure monitor when it is using ,Don’t move and
avokd electromagnetic interference and noise interference when measuring that to
avoid to measure error。
- When the screen display the battery for one degree,it means that low Voltage and
must change the new one to void to measure error。
- Babies, young children or individuals who cannot express their consent are not
suitable to take blood pressure measurement.
- Keep the equipment away from children and pets.
- Blood pressure readings may change in case of pregnancy. Pregnant women can
consult their doctor before taking measurement。
- Individuals with serious arteriosclerosis are not suitable to take blood pressure
measurement。
- Self-measurement is not medical treatment lf there are unusual values, please
consult your doctor。

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site
survey should be considered. If the measured field strength in the location in which the “XXX” is
used exceeds the applicable RF compliance level above, the Medical XXX should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the “XXX”.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where Pis the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and
reflection from structures, objects and people.
