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 can't 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. Make
sure that small children are kept away from the device
and accessories.
