Road safety
Avoid listening with your headphones in situations where hearing must not be 
impaired.
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.
Do not turn the volume up high all at once, especially when using headphones.
Turn up the volume gradually so that loud sound will not hurt your ears.

sounds and to be considerate to the people around you.

If there is lightning when you are using the player, take off the headphones 
immediately.
If you experience an allergic reaction to the supplied headphones, stop using
them at once and contact a doctor.

If condensation forms in the player, leave it turned off until the condensation 
disappears. If you use the player with condensation present, a malfunction 
may result.
