Caring for and Troubleshooting the Polar FT4 Heart Rate Monitor

Published:  01/03/2018

The Polar FT4 is my recommended heart rate monitor.

Often issues with picking up heart rate are related to the strap.  The electrodes do need to be wet for good conductivity.  Run them under a faucet so they are soaked.  Make sure you are washing the strap with mild soap and warm water after each use.

Please make sure that you completely disconnect the transmitter from the strap after each use to prevent corrosion on the snaps. Also leaving it connected will drain the battery prematurely.

The strap will last about 12 - 18 months.  The electrodes will wear out with use and washing.   If the electrodes are worn out you will also experience erratic or zero readings.

Try taking the battery out of the transmitter and letting the unit sit for about 5 minutes. This helps to reset the transmitter. Once done put the battery back in and make sure to wet the strap before putting it on.
