Other heart rate devices can be used normally during the Bodyguard 2 measurement. Bodyguard 2 device records the heart rate signal through the electrodes so it does not receive signals from other devices. The Bodyguard 2 also does not disturb the function of other devices since it does not send any signals.

If you use some other heart rate device at the same time, make sure that the device is not over the Bodyguard's cable and it will not accidentally rip off the electrodes from the skin or the cable from the electrodes.
