Possible Chest Strap Heart Rate Problems
All Bodyguard
®
machines are compatible with the Polar wireless heart rate system. This includes a chest strap and a receiver. The receiver is an
integral part of the machine and it is hidden inside. The chest strap is an option on all machines and can be purchased from Bodyguard

The chest strap electrodes need to be moistened in order to send a strong signal. Radio and neon light interferences can also reduce the
strength of the signal.
