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.
Hearing experts offer the following suggestions to protect your
hearing:
Reduce the time you use the receiver, earbuds, headphones,
speakerphone, or earpieces at high volume.
Do not increase the volume to block noisy surroundings.
Reduce the volume if you cannot hear people speaking near
you.
Safety of Children
Please comply with all precautions with regard to children's
safety. Letting the child play with your device or its accessories,
which may include parts that can be detached from the device,
may prove dangerous, as it may present a choking hazard.
