Place the strap with the module in place on the subject. If the strap is not in contact with the skin, it will not work.&nbsp; Connect the receiver to an interface and start the data collection software. Make sure the module and the receiver are at the same level to receive the best signal.<\/li>\n<li><strong>Secondary Test: <\/strong>The sensor supports Bluetooth<sup>\u00ae<\/sup> connection (without the need for the receiver) if it has the removable Polar Heart Rate Module. Connect the sensor via Bluetooth to your LabQuest 2, LabQuest 3 or device running Graphical Analysis app. If the strap is not in contact with the skin, the sensor will not show in the list of available devices.
