Cleaning CD/DVD-ROM
A dusty CD/DVD-ROM or dust-accumulated tray causes the device to fail to read data correctly.
Follow the procedure below to clean the tray and CD/DVD-ROM regularly:
1. Make sure that the equipment is powered (the POWER/SLEEP lamp is lit).
2. Press the Eject button on the front of the optical disk drive.
The tray comes out.
3. Hold the CD/DVD-ROM lightly and take it out from the tray.
NOTE: Do not touch the signal side of the CD/DVD-ROM with your
hand.
4. Wipe the tray with a dry soft cloth.
IMPORTANT: Do not wipe the lens of the optical disk drive. Doing
so may damage the lens and may cause a malfunction of the drive.
5. Gently push on the tray front to close the tray.
6. Wipe the signal side of the CD/DVD-ROM with a dry soft cloth.
IMPORTANT: Wipe CD/DVD-ROMs from the center to the outside.
Use only CD/DVD-ROM cleaner if necessary. Cleaning a CD/DVD-
ROM with record spray/cleaner, benzene, or thinner causes damage to
the CD/DVD-ROM contents. At worst, inserting the CD/DVD-ROM
into the optical disk drive may cause failure of the equipment.
