You can physically expand the memory up to 4 GB, but the

 

total amount of usable memory available will be less depend-

*3

ing on the actual system configuration.

A segment of the main memory is allotted automatically

 

depending on the computer’s operating status. The size of the

 

Video Memory cannot be set by the user. The size of Video

memory is allotted depending on the operating system.

1 GB = 1,000,000,000 bytes. Your operating system or some

application software will report as fewer GB.

Data transfer speeds indicate values measured by Matsushita Electric

 

Industrial Co., Ltd. The data transfer rate of DVD per 1X speed is

1,350 KB/s. The data transfer rate of CD per 1X speed is 150 KB/s.

Performance of CD-R, CD-RW, DVD-RAM, DVD-R, DVD-R

 

DL, DVD-RW, +R, +R DL, and +RW cannot be guaranteed

 

depending on writing status and recording format. Also, some

 

data cannot be played back depending on the disc, settings,

 

and environment being used. Does not support writing to

DVD-R DL.

If an unbalanced disc (e.g., a disc with which the balance has been

 

displaced from the center) is inserted, the speed may become

slower if there are large vibrations while the disc is rotating.

Only non-cartridge type or removable cartridge type can be

used.

DVD-R is compatible with 4.7 GB (for General) playback.

 

DVD-R (for Authoring) playback is compatible with discs

 

recorded using Disc-at-Once recording.

*10 Depending on the disc, the writing speed may become slower.

*11 A 16,777,216 color display is achieved by using the dithering function.

*12 Display may be impossible using some connected external displays.
