Buttons should not be pressed while the unit is submerged in water. Wireless transmission does not work under water. After swimming, rinse the watch in cold water and dry with a soft cloth.

How does the MIO Alpha work?

Two light beams and an electro-optical cell “sense” the volume of blood under your skin. Because the blood volume pulsates in the rhythm of the heart, so does the signal from the electro-optical cell. This signal is processed by an advanced electronics circuit and passed on to a highly specialized computer program that is embedded in the ALPHA. To date, the stumbling block with this type of technology has been the arm movements while walking or running strongly interfere with the electro-optical signal to the point that it is no longer possible to extract the heart rate from it.

In order to solve this problem the ALPHA has been provided with a separate motion detector. The computer program is able to use the information from this detector to compensate for the disturbance that is generated in the electro-optical signal by walking or running motions. As a result, the ALPHA can display an accurate heart rate even during motion-intense activities.
