Care and Maintenance

Never use the device in a strong magnetic field as this may result in data being lost.

Avoid exposing the player to strong sunlight, heat sources, high humidity and extreme temperatures.

Keep your MP3 player dry. If it gets wet, wipe it dry immediately. Keep your MP3 player away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new.

Handle your MP3 player carefully; do not drop it.

Modifying or tampering the MP3 player’s internal components can cause malfunction and might invalidate its warranty. If your player is not performing as it should, take it to your local RadioShack store for assistance.

Listening Safely

To protect your hearing, follow these guidelines when you listen to the player:

Do not listen at extremely high volume levels. Extended high volume listening can lead to permanent hearing loss.

Do not wear earphones while operating a motor vehicle or riding a bicycle. This can create a traffic hazard and could be illegal in some areas.

Set the volume to the lowest setting before listening. After you begin listening, adjust the volume to a comfortable level.

After you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.
