This earmuff provides level-dependent and entertainment audio facilities. It can also amplify external noise by up to three times (conversation, animal, noises, natural sounds, ect).
It provides ideal protection and allows warning signals to be heard even in very noisy environments. Examples of typical applications:

Whenever batteries are low, the red led (that lies on the cup) intensity fades. The more your batteries are getting low, the more the red light is going to fade. Whenever batteries are low, the headset does not turn and the low natural sounds are not anymore amplified. Then you need to replace the batteries. Please follow the previous section’s procedure.

Putting on the headset
