Routine Maintenance (Cleaning)

Cleaning of lens
The lens on the Built-in DVD-RAM drive may be covered with dust and/or dirt while the
Built-in DVD-RAM drive is used for a long time. This may cause data read/write to be done
incorrectly.
While the cleaning frequency varies depending on the usage environment and frequency of
the Built-in DVD-RAM drive, it is recommended to clean the lens once for two months by
using the attached lens cleaner. See the next chapter for details of the cleaning.
Cleaning of disk
While a disk is used for a long time, the data side may be covered with dust and/or dirt. This
may cause data read/write to be done incorrectly. See the next chapter for details of the
cleaning.
