THE SCIENCE BEHIND ALPHA
Light beams & an electro-optical cell “sense” the volume of
blood under your skin
Optical Sensor
Electronic Circuit
Pulse
Sensor LEDs
Heart Rate
Alpha is a true scientific breakthrough. Technology proven accurate at rest in
medical use is now robust enough for sport. Sophisticated algorithms are applied
to the pulse signal so that the heart’s true rhythm can be detected even while
running at performance speeds.
WEARING YOUR ALPHA
To use the heart rate monitor on your Alpha watch, you must:
t Fasten the watch snugly so the optical sensor on the back of the watch makes
tight contact with your skin. The tighter you can wear the watch, the better.
t Wear the watch above—not on—your wrist bone; wear it higher on the forearm
when using Alpha as a heart rate monitor, especially if you have a small wrist.
t Alpha’s performance is optimized with greater blood flow. Exercise for a few
minutes to increase your blood flow before turning on the heart rate monitor.
