USING THE EARPLUG
Power On
Press and hold the Power/Volume button (3:A) on each earplug for two seconds. Release the button
when you hear a tone.
Environmental Listening
When the earplugs are powered on, there are three environmental listening levels (low, medium and
high) that allow sounds to pass through in quiet environments while restricting the volume level in
loud environments. Upon power on, the earplugs default to the low setting, which reproduces the
environmental sounds at a reduced level and has a maximum output of 66 dB(A). Quickly press and
release the Power/Volume button to toggle through the three settings. The second setting is medium,
which will reproduce the environmental sounds at approximately the same volume as if there were no
