Heat may build up in the Reader while charging, or if it 

is used for an extended period of time.

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.
