How do the ear protectors work?
The ear protectors make a beep when the on/off button is pressed to switch them on and off.
The + / - buttons are used to adjust the amplification volume according to your activity.
Recommendations for use:
Depending on your activity (shooting, hunting, etc.), the venue (shooting range, lowlands, forest, etc.), you can adjust the amplification volume.
While you need to be able to hear, there is no point in over-amplifying it.
When outdoors, pay attention to the wind, which will create a blast effect in the microphones.
