How the Go Wireless Exercise Heart Rate Works
The Go Wireless Exercise Heart Rate measures a person's heart rate by registering
the small electrical signals carried across the surface of a person's skin each time his
or her heart contracts. The Polar Transmitter Module detects each electrical signal
from the heart through the electrodes on the chest strap. The heart rate information is
then wirelessly transmitted using a Bluetooth radio to supported mobile devices.
Collecting Data with Bluetooth Smart Devices
Ensure that the Polar Transmitter Module is attached to the Exercise Heart Rate
Strap securely. Locate and record the ID on the side of the Polar Transmitter
Module. This is a unique sequence of six numbers and/or letters (e.g.,
ID:XXXXXX). Secure the strap around the subject's chest. The strap should be
located just below the chest muscles. Attach the hook to the other end of the strap to
secure the sensor. Verify that the Polar Transmitter Module is located in the center of
the chest in an upright position. The sensor is now ready for data collection.
