How your athletes should wear the Firstbeat Sports Sensor

General guidelines

• Pay close attention that your athletes are properly wearing and moisturizing the HR strap to get good data quality. Good data quality is the prerequisite for a training analysis done by the Firstbeat algorithms.

• If you wear the HR Strap and Sensor while commuting to the training facility data gets recorded during this time, too. To avoid extra data before and at the end of a measurement, the sensor should be worn only when starting the workout and

• It should be avoided leaving the Sensor attached to the HR Strap when it is not being worn. Although artifact data is removed programmatically, in some cases this might cause extra artifact data to your measurement.

Instructions for your athletes:

Before recording

1. Dampen the skin under the area the Sensor will be placed.

2. Attach the textile strap around your chest and adjust until securely in place.

3. Attach Sensor to the strap.

Whilst recording

• The Sensor will automatically start recording R-R intervals once properly attached to the athlete’s chest using the strap.

• Sensor LED blinks at 1s intervals when it is waiting to detect data. LED flashes at 5 seconds intervals when Sensor is recording.

After recording

1. Take off the strap and detach the Sensor from strap. The Sensor will stop recording automatically when it does not detect any R-R signal.

   • Removing the Sensor from the strap improves battery life and ensures R-R interval recording ends appropriately.

2. The Sensor remains in standby mode for 30 minutes to allow for a smooth data download process. After 30 minutes, the Sensor moves to sleep mode to reduce draining the battery. It is also possible to download data in sleep mode but there may be minor delays in Sensors being recognized. 

3. Rinse the strap under running water and hang it to dry. Additional maintenance instructions are available here.
