Polar. If you are having some problems with the reception, please use the following
troubleshooting check list.
Troubleshooting Check List – Table 1
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.
Possible Contact Heart Rate Problems
