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 expe-
rience 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:
Preventing Hearing Damage
•
Reduce the time you use the receiver, earbuds, head-
phones, speakerphone, or earpieces at high volume.
• Do not increase the volume to block noisy surround-
ings.
•
Reduce the volume if you can't hear people speaking
near you.
Safety of Children
Please comply with all precautions with regard to chil-
dren'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 chil-
dren are kept away from the device and accessories.
Environmental Protection
Follow all the local regulations regarding the disposal of
your devices or electrical accessories (such as chargers,
headsets, or batteries). Recycle them. Do not dispose of
an exhausted battery or a used device in a garbage can.
