Additional Information
On screen burn
In general, screen burn may develop on OLED panels because of the
characteristics of the materials which are used to achieve high definition of
images. If you keep displaying a still image at the same position of the display,
or repeat displaying the same image, the image will be burned in and become
unable to be removed.
Images that easily develop screen burn
 Widescreen images with black bars above and below them (letterbox images)
 Images with a 4:3 aspect ratio
 Photos and still images that rest on the display for a long time
To prevent screen burn
 Display images on full screen.
Set "Zoom Settings" option to "Auto" or "Full" (  page 61).

On cleaning

 Clean the player's case with a soft cloth, such as a cleaning cloth for
eyeglasses.
 If the player's case becomes very dirty, clean it with a soft cloth slightly
moistened with water or a mild detergent solution.
 Do not use any type of abrasive pad, scouring powder, or solvent, such as
alcohol or benzene, as it may mar the finish of the case.
 Be careful not to let water get into the player from the opening near the
connector.
 Clean the headphone plug periodically.
If you have any questions or problems concerning the player, please consult
your nearest Sony dealer.
