Cleaning the optical lens
After the CD-ROM drive has been used for a long time, the optical lens for data reading may
become dirty, causing data on the CD-ROM disk to be read incorrectly. To clean the optical lens:
1 Use the small brush provided with the CD-ROM cleaning disk to straighten the special brush
for cleaning on the rear surface of the CD-ROM cleaning disk.
2 Press the Eject button. The tray of the CD-ROM unit comes out.
3 Place the CD-ROM cleaning disk on the tray of the CD-ROM unit with the red triangle mark
towards you.
4 Press the Eject button. The tray of the CD-ROM unit goes in.
5 Wait for about 20 seconds.
(If there are clicking sounds or the disk rotates fast, this is not a sign of a failure.)
6 Check that the BUSY LED is off, then press the Eject button and remove the CD-ROM
cleaning disk.
