Bluetooth® button once.

The typical range between a Bluetooth®enabled
device and the 3M Pro Electronic Hearing Protectors
is approximately 25 feet. This distance may vary
depending on the device. As the distance between
the Bluetooth®enabled device and the hearing
protector increases, the risk of the signal dropping
also increases.
For best results, keep your Bluetooth®enabled
device on your body or within an arm’s length of
the 3M Pro Electronic Hearing Protectors while
using Bluetooth®Mode.
