Road safety
Do not use headphones while driving, cycling, or operating
any motorized vehicle. It may create a traffic hazard and is
illegal in many areas. It can also be potentially dangerous to
play at a high volume while walking, especially at pedestrian
crossings. You should exercise extreme caution or
discontinue use in potentially hazardous situations.
Preventing hearing damage
Avoid using the headphones at a high volume. Hearing
experts advise against continuous, loud and extended play.
If you experience a ringing in your ears, reduce the volume
or discontinue use.
Caring for others
Keep the volume at a moderate level. This will allow you to
hear outside sounds and to be considerate to the people
around you.
Warning
If lightning occurs while you are using the Reader, take off
the headphones immediately.
