SET UP PROCEDURES
Download the Free iHealth MyVitals App
Prior to first use, download and install “iHealth MyVitals”from the App Store or Google Play Store. Follow the
on-screen instructions to register and set up your personal account.
Access the iHealth Cloud Account
Your iHealth account also gives you access to the free and secure iHealth cloud service. Go to
www.ihealthlabs.com and sign in with the same account.
Charge Battery before First Use
Connect the monitor to a USB port using the charging cable provided until indicator steady.
BODY POSTURE DURING MEASUREMENT
Blood pressure can be affected by the position of the cuff and your physiologic condition. It i
s
very important that the cuff is positioned at your heart level during blood pressur
e
measurements.
1. Sit comfortably with your feet flat on the floor without
crossing your legs. Stay still during measurement. Do not
move your wrist, body, or the monitor.
2. Place your hand palm-side up in front of you and leave 1-2cm
between the monitor and the bottom of your palm. If the
monitor is correctly placed, iHealth logo will be facing
upright.
3. The center of the cuff should be at your heart level.
4. It is advised to place the monitor’s travel case under your
arm for support and to keep your arm at optimal height for
measurement.
TAKING YOUR BLOOD PRESSURE READING
1. Apply the cuff or press the START/STOP button, the monitor will activate and begin to detect your wrist position.
2. Adjust the height of your wrist, the monitor will detect your wrist position and the measurement will start ONLY when the
correct position is detected. When the position is correct, press "START/STOP" button again to start measurement.
Wrist position too low Wrist position too high Wrist position good
3. Then the cuff will be slowly inflated. The blood pressure and pulse will be measured during inflatio
n
Inflation will stop as soon as the blood pressure and pulse rate have been calculated and displayed o
n
the screen. The result will be automatically stored in the memory, and all results will be uploaded to th
e
App automatically upon the next successful Bluetooth connection.
SYNC TIME AND RESULTS VIA BLUETOOTH
Connect to iOS Device via Bluetooth
• Press the START/STOP button for 3 seconds, the Bluetooth indicator will begin flashing.
• Enable the Bluetooth on your iOS device(Setting->General->Bluetooth->On) .
• Launch the "iHealth MyVitals" app to initiate the connection, the Bluetooth indicator will light up and stop flashing when a
successful connection is established.
• When sync is processing, the sync indicator flash and , when sync is finished, the sync indicator lights up .
Connect to Android Device via Bluetooth
• Press the START/STOP button for 3 seconds, the Bluetooth indicator will begin flashing.
• Enable the Bluetooth on your Android Device.
• When using the monitor for the first time, you should pair the monitor to the Android device. Go into your device’s setting to
pair it with your Android device. Check the Bluetooth menu for the model name of your monitor (BP7SXXX) to appear, and then
select it to pair. This may take up to 30 seconds and your monitor’s Bluetooth indicator will light up when a connection has been
established.
• Launch the “iHealth MyVitals” app to sync with your monitor.
• When sync is processing, the sync indicator flash and , when sync is finished, the sync indicator lights up .
• Please repeat these steps when you switch to another Android device with the monitor.
Remember to:
1. Make sure your wrist size is within cuff circumference; see the range in “SPECIFICATIONS”
2. Measure on the same wrist each time.
3. Stay still and calm for one to one and half minutes before taking a blood pressure measurement. Prolonged over-inflation of
the bladder may cause bruises of your wrist.
4. Keep the cuff clean. Cleaning the cuff after every 200 times of usage is recommended. If the cuff becomes dirty, clean it with
a moistened cloth. Do not rinse the monitor or cuff with running water.
5. Press the “START/STOP” button at any time to interrupt a measurement.
Note: Physical activity, eating, drinking, smoking, excitement, stress, and many other factors influence blood pressure results.

GENERAL SAFETY AND PRECAUTIONS
1. Read all of the information in the User Guide and other provided instructions before operating the unit.
2. Consult your physician for any of the following situations:
a) The application of the cuff over a wound or inflamed area.
b) The application of the cuff on any limb with intravascular access or therapy, or an arteriovenous (A-V) shunt.
c) The application of the cuff on the arm on the side of a mastectomy.
d) Simultaneous use with other medical monitoring equipment on the same limb.
e) The blood circulation of the user needs to be checked.
3. Do not use this product in a moving vehicle as this may result in inaccurate measurements.
4. Blood pressure measurements determined by this product are equivalent to those obtained by professional healthcare
practitioners using the cuff/stethoscope auscultation method within the limits prescribed by the American National Standard,
Electronic or Automated Sphygmomanometer. This device is also clinically validated according to the 2010 Protocol of the
European Society of Hypertension (ESH 2010).
6. If an Irregular Heartbeat (IHB) is detected during the measurement procedure, the IHB symbol will be displayed in the
“iHealth MyVitals” APP. Under this condition, the Wireless Blood Pressure Wrist Monitor can keep functioning, but the results
may be inaccurate. Please consult your physician for accurate assessment.
The IHB symbol will be displayed under 2 conditions:
1) The coefficient of variation (CV) of pulse period >25%.
2) The difference of adjacent pulse period is ≥0.14s and more than 53 percent of the total number of pulses readings falls within
this definition.
7. Please do not use any cuff other than that supplied by the manufacturer as this may result in inaccurate measurements.
8. For information regarding potential electromagnetic or other interference between the blood pressure monitor and other
devices together with advice regarding avoidance of such interference, please see ELECTROMAGNETIC COMPATIBILITY
INFORMATION. It is suggested that the blood pressure monitor should be operated at least 10 meters away from electric or
wireless devices (e.g. routers, microwave oven, etc.)
9. If the blood pressure measurement (systolic or diastolic) is outside the rated range specified in part SPECIFICATIONS, the
monitor will immediately display a technical alarm on the screen. In this case, repeat the measurement ensuring that the proper
measurement procedures are followed and/or consult with your medical professional. The technical alarm is preset in the factory
and cannot be adjusted or inactivated. This technical alarm is assigned as low priority according to IEC 60601-1-8. The technical
alarm does not need to be reset.
10. This device requires a medical AC adapter with an output of DC 5.0V that complies with IEC 60601-1/UL 60601-1 and IEC
60601-1-2/EN 60601-1-2 such as ASP5-05010002JU (input: 100-240V, 50/60Hz, 200mA; output: DC 5V, 1.0A). Please note that
the monitor jack size is USB mini B. The USB jack should be used for charging only.
This Monitor is designed for adults and should never be used on infants, young children, pregnant or pre-eclamptic patients.
Consult your physician before use on children.
This product might not meet its performance specifications if stored or used outside the specified temperature and humidity
