Prerequisite for using the Quardioarm is downloading the appropriate app from the App Store / Play Store on a smartphone. I use the Samsung Galaxy S 5. the downloaded app needs to be personalized to FIRST TIME INSTALLATION. Coupling (pairing) via Bluetooth is done by the smartphone is held directly to the Quardioarm. In order to carry out a blood pressure measurement called the app and after a short time the invitation smartphone via Bluetooth will be connected to the Quardioarm. The Quardioarm is powered by 4 AAA batteries and activated in conjunction with the app automatically. By default, a personalized measurement is provided. There is also a visitor mode that does not store the measurement in the course. The Bluetooth activation, a round green Start button appears. The Quardioarmmanschette unroll and directly above the flexor create the (left) arm so that the Quardioschriftzug pointing downwards. By pressing START, the cuff inflated within about 15 seconds with moderate (not unpleasant) pressure. At the same time, this process can be followed on the smartphone. If the corresponding pressure reaches unfolds the air until the completion of the measurement. The result of the upper pressure (SYS) - lower pressure (DIA) and pulse can now be read on the phone and a color indicator shows on the color green-yellow-orange-red a short evaluation on. The user is at liberty if he archives the measurement with OK or not save.
It is advisable to read the self-explanatory instructions carefully. I initially had problems to build up the Bluetooth connection / pairing and recorded due to its connection to the support (getqardio.com/support). Within a short time I got the solution to the problem.
