Table 1
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
®
Polar. If you are having some problems with the reception, please use the following
troubleshooting check list
.
The above table should help properly diagnose the problem. There is also misconceptions that the signal is immediate. 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.
