Cleaning of Lens

Use the lens cleaner coming with the Built-in DVD-RAM drive to clean the read/write head
in the Built-in DVD-RAM drive.
(Feature of lens cleaner)
The lens cleaner is made of lens cleaner solution and thus of the liquid type, which enables
the dirt on the lens to be removed effectively.
(Use of lens cleaner)
Turn on the power of the Built-in DVD-RAM drive.
1.
Infiltrate the five white cloth pieces on the lens cleaner with cleaning solution once
2.
by using the blush of the attached cleaning solution container.
If the cloth pieces are infiltrated with much solution, the solution may fly in the
Built-in DVD-RAM drive to cause the occurrence of a fault.
Face the arrow (↑) appearing on the label printing side of the lens cleaner to the
3.
depth of the Built-in DVD-RAM drive, put the lens cleaner on the tray in the similar
way as a CD, and close the tray.
While the lens cleaner is identified, the indicator lamp illuminates for about 15 to
30 seconds.
After the indicator lamp goes off, press the eject button to eject the lens cleaner
4.
from the tray.
Depending on the Built-in DVD-RAM drive type, the tray is opened automatically.
This does not indicate the occurrence of an error.
Put the removed lens cleaner into the exclusive storage case with the brush side
facing downward.
(Remarks)
The cleaning frequency is desired to be once per 2 months while it varies
depending on the usage environment and frequency of the Built-in DVD-RAM
drive. If data read/write error occurs, it is recommended to clean the lens more
frequently (e.g., once per month).
When some problems occur in data read/write operations despite the lens
cleaning, repeat the procedure described in (Use of lens cleaner) above without
use of the cleaning solution. If the problems cannot be eliminated still, any other
cause may be suspected. Contact your service representative.
(Notes)
The attached lens cleaner should be exclusively used for the Built-in DVD-RAM
drive. Do not use the lens cleaner to any other drives. Failure to follow it may
cause the drives to be defected.
If the brush wastes or is polluted heavily, purchase a new brush. Using old lens
cleaner (approx. 60 times used) could damage the lens in the Built-in DVD-RAM
drive.
For the storage, put the lens cleaner into the exclusive plastic case coming with
the Built-in DVD-RAM drive. Do not place the lens cleaner in an area subject to
direct sunshine or a high-temperature area.
Do not any cleaning solution other than the attached one.
