2. BEFORE EXERCISE
Wear the Transmitter
Wear the transmitter to measure heart rate.
1. Attach one end of the transmitter to the elastic strap.
2. Adjust the transmitter’s strap length to fit snugly and
comfortably. Secure the strap around your chest, just below the
chest muscles, and buckle the strap to the transmitter.
3. Lift the transmitter off your chest and moisten the two grooved
electrode areas on the back. Check that the wet electrode areas
are firmly against your skin and that the Polar logo is in a
central, upright position.
