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.
