9. Do not turn your phone on or off while the device is in close proximity to your ear.
10. Use accessories, such as earphones and headsets with caution. Ensure that cables are tucked away safely and
do not touch the antenna.
Caution:
Avoid potential hearing loss.
Prolonged exposure to loud sounds (including music) is the most common cause of preventable hearing loss. Some
scientific research suggests that using portable audio devices, such as portable music players and cellular telephones,
at high volume settings for long durations may lead to permanent hearing loss. This includes the use of headphones
(including headsets, ear buds and Bluetooth®, or other wireless devices). Exposure to very loud sound has also been
associated in some studies with tinnitus (ringing in the ear), hypersensitivity to sound, and distorted hearing. The amount
of sound produced by a portable audio device varies depending on the nature of the sound, the device, the device
settings and the headphones. Hence, individual susceptibility to noise-induced hearing loss and other hearing problems
can vary. Please follow these important guidelines for hearing loss prevention:
1. Set the phone’s volume in a quiet environment and select the lowest volume for which you can hear clearly.
2. When using headphones, turn the volume down if you cannot hear the people speaking near you or if the person
sitting next to you can hear what you are listening to.
3. Do not turn the volume up to block out noisy surroundings. If you choose to listen to your portable device in a
noisy environment, consider using noise-cancelling headphones to block out background noise.
4. As the volume increases, less time is required before your hearing could be affected, so consider limiting your
listening time.
5. Avoid using headphones after exposure to extremely loud noises (e.g.: live concerts) that might cause temporary
hearing loss which, in turn, might cause unsafe volume levels to sound like normal levels.
6. Do not listen at any volume that causes you discomfort. If you experience ringing in your ears, hear muffled
speech or experience any temporary hearing difficulty after listening to your portable audio device, discontinue
use and consult your health care provider.
