a portable audio device varies depending on the nature of the sound, the device settings, and the
headphones that are used. As a result, there is no single volume setting that is appropriate for everyone
or for every combination of sound, settings, and equipment.
You should follow some common sense recommendations when using any portable audio device:
●
Always turn the volume down before plugging the earphones into an audio source.
●
Set the volume in a quiet environment and select the lowest volume at which you can hear
adequately.
●
Be aware that you can adapt to higher volume settings over time, not realizing that the
higher volume may be harmful to your hearing.
●
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.
●
Do not turn the volume up to block out noisy surroundings. If you choose to listen to
your portable device in a noisy environment, use noise-cancelling headphones to block
out background environmental noise. By blocking background environment noise, noise
cancelling headphones should allow you to hear the music at lower volumes than when
using earbuds.
●
Limit the amount of time you listen. As the volume increases, less time is required before
you hearing could be affected.
●
Avoid using headphones after exposure to extremely loud noises, such as rock concerts,
that might cause temporary hearing loss. Temporary hearing loss might cause unsafe
volumes to sound normal.
●
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 doctor.

Operating Environment
Remember to follow any special regulations in force in any area, and always switch your mobile device
off whenever it is forbidden to use it, or when it may cause interference or danger. When connecting the
mobile device or any accessory to another device, read its user's guide for detailed safety instructions.
Do not connect incompatible products.
Using Your Mobile Device Near Other Electronic Devices
Most modern electronic equipment is shielded from Radio Frequency (RF) signals. However, certain
electronic equipment may not be shielded against the RF signals from your wireless mobile device.
Consult the manufacturer to discuss alternatives.
Implantable Medical Devices
A minimum separation of six (6) inches should be maintained between a handheld wireless mobile
device and an implantable medical device, such as a pacemaker or implantable cardioverter defibrillator,
to avoid potential interference with the device.
Persons who have such devices:
●
Should ALWAYS keep the mobile device more than six (6) inches from their implantable
medical device when the mobile device is turned ON;
●
Should not carry the mobile device in a breast pocket;
●
Should use the ear opposite the implantable medical device to minimize the potential for
interference;
●
Should turn the mobile device OFF immediately if there is any reason to suspect that
interference is taking place;
●
Should read and follow the directions from the manufacturer of your implantable medical
device. If you have any questions about using your wireless mobile device with an
implantable medical device, consult your health care provider.
