become soiled by dust or dirt, the unit may not read discs properly.

malfunction.
• Do not apply excessive force to the tray in the open position, doing so could damage the
tray.

being accessed. Doing so could cause it to malfunction. In addition, after running an
application involving access to a disc, do not open the DVD-ROM drive or remove the
disc until after the application has been closed.

recommended if it malfunctions.
