Things to do before using WIWE
After unpacking WIWE, before usage, the mobile application required for operation needs to be downloaded and started. Once this is
done and the device is turned on by pressing the button on the top of the device, WIWE – within the normal operational temperature
threshold and on an adequate battery level – can be utilized right away. In case of extreme storage temperature you need to wait while
the temperature of the device’s case reaches the normal operational threshold, which means approximately 10 minutes from -25 °C to
+5 °C and approximately 5 minutes from +60 °C to +40 °C in case of an environment with normal room temperature.
4.1
Ready for operation
For the proper operation of WIWE, please check the conditions below before every usage:
Intactness of the device. Make sure that the device is not damaged and in a usable condition!
Cleanness of the sensors.
Battery level. The device is fully charged when the 4 LED lights on top are lit when you turn on the device. If at least two of the
LED lights are not lit, the accumulator must be charged before use. See Charging the accumulator section.

Measuring
Users can take a measurement with the help of the WIWE devie and the mobile application, during which the resulting measurements
can be viewed on the phone screen and these can be shared with others (eg. with your doctor).
5.1
Before measuring:
Please consider the points below in order to get precise measurement results:
Electrodes should be in contact with the skin of the fingertips directly.
Fingertips should completely cover the electrodes.
If your skin is very dry, make it moist with a wet cloth before measuring.
If the electrodes are contaminated, remove the contamination from the surface with a soft wipe.
When measuring, the hands should not touch any other body part. Please bear in mind that the skin of your left and right hand cannot
touch during measuring, and neither the user’s skin, nor the device’s electrodes can touch metal devices. Otherwise measurement
cannot be performed properly.
Do not move during the measuring, because any muscle movement can cause false measurement.
Measuring should be performed preferably in sitting or lying position, but not standing.
5.2
Account registration
Since WIWE and the application can be used by more than one user, medical data and measurements of the individuals are suggested
to be separated. For this, you have the opportunity to create accounts on your mobile phone.
Account registration cannot be skipped, however, there is a possibility to initiate measuring anonymously, without an account.
You can find detailed information about registering an account in the Advanced guide of your mobile application’s Information
section.

Measurement:
After initiating a measurement on your smartphone, press the ON button as the appearing illustration shows you to on your phone in
order to establish the radio (Bluetooth) connection.
Measurement is done by placing the same fingers of your left and right hand on the sensors.
Touch the electrodes and gently hold your fingers on them. For a successful
measuring, a preparatory process is also required, when the user places their same
two fingers of each of their hands on the WIWE sensors and becomes relaxed.
During the preparatory period, the application checks whether the contact was
adequate, and whether the data received from WIWE are suitable for starting a
measurement. The preparatory period is 10 seconds long.
In case of a normal measurement the mobile phone, in individual cases the process
indicator on the front of the WIWE shows that the measuring process has started.
Letting go of the sensors within 30 second will result in the interruption of
measurement.
After 60 seconds, the application indicates on the phone screen when data collection is finished. During data collection, the application
displays the ECG, their pulse and blood oxygen saturation level of the user who touched the sensors.
At the end of the measurement, evaluation may take a few seconds, then you can check the results on your mobile phone.
In case of an unsuccessful measurement please follow the instructions appearing on your phone. Repeat the measurement.
When the failure signaling LED blinks on the device, it means that ECG signs are unstable or weak. In this case repeat the
measurement.
The device will only start measuring, if the battery voltage level allows at least one measurement.
5.4
Frequent causes of inaccurate measurement
1.
Inadequate contact between the electrodes and the fingers.
2.
Left hand skin and right hand skin touch during measuring.
5.5
Results display screen
After the measurement and evaluation, measurement data can be viewed on your phone screen. It is recommended to show these results
to a doctor as well, so that any changes in your health may be diagnosed by them.
To have a quick overview of all these data, measurement and evaluation data are summarized on the Evaluation screen.
The evaluation of the main measured data is indicated by 3 circles in a row of the same
diameter on the screen. In the center of the circles, ECG (Electrocardiography), AF (Atrial
fibrillation) and VH (Ventricular heterogeneity) abbreviations show which health
parameter group they stand for. The filling colors of the circles can be green, yellow or
red, depending on the evaluation of the measurement’s results. Green color stands for
„normal” condition, yellow means „minor deviation from normal condition” and red is
„major deviation from normal condition”.
Underneath the circles, SPO

button shows oxygen saturation, whereas Bpm shows the
pulse value.
