Avoiding Hearing Damage Permanent hearing loss may occur if the
receiver, earbuds, headphones, speakerphone, or earpieces are used at
high volume. Set the volume to a safe level. You can adapt over time to
a higher volume of sound that may sound normal but can be damaging
to your hearing. If you experience ringing in your ears or mued speech,
stop listening and have your hearing checked. The louder the volume,
the less time is required before your hearing could be aected. Hearing
experts suggest that to protect your hearing:
 Limit the amount of time you use the receiver, earbuds, headphones,
speakerphone, or earpieces at high volume.
 Avoid turning up the volume to block out noisy surroundings.
 Turn the volume down if you can’t hear people speaking near you.
