Preventing Hearing Damage
Using the receiver, earbuds, headphones, speakerphone, or
earpieces at high volume can result in permanent hearing loss.
Be extremely careful when listening at high decibel levels. Set
the volume to a safe level. If you experience strange sounds in
your ears like ringing or if you hear muffled speech, get your
hearing checked. If you continue to use high volume, your
hearing will soon get affected.
