Measuring Your Heart Rate - Polar Electro F11 User Manual

1.4 MEASURING YOUR HEART RATE

To measure your heart rate, you need to wear the transmitter.
Heart rate coding reduces interference from other heart rate monitors that are close by. To make sure that the code search is
successful and ensure trouble-free heart rate monitoring, keep the wrist unit within 3 feet/1 meter of your transmitter. Check
that you are not near other people with heart rate monitors or any source of electromagnetic disturbances (for further
information on interference, see the chapter Precautions on page 77).
