63 Important Information*1 1 MB = 1,048,576 bytes*2 A segment of the main memory is allotted automatically depending on the computer’s operating status. The size of the VideoMemory cannot be set by the user.*3 1 GB = 1,000,000,000 bytes. Operating system or some application software will report as fewer GB.*4 Data transfer speeds indicate values measured by Matsushita Electric Industrial Co., Ltd. The data transfer rate of DVD per 1Xspeed is 1,350 KB/s. The data transfer rate of CD per 1X speed is 150 KB/s.*5 Performance of CD-R, CD-RW, DVD-RAM, DVD-R, DVD-RW, +R, +R DL, and +RW cannot be guaranteed depending on writingstatus and recording format. Also, some data cannot be played back depending on the disk, settings, and environment beingused.*6 In the case of DVD-RAM, only non-cartridge disks or removable cartridge disks can be used.*7 DVD-R is compatible with 4.7 GB (for General) playback. DVD-R (for Authoring) playback is compatible with disks recordedusing Disk-at-Once recording.*8 If an unbalanced disk (e.g., a disk with which the balance has been displaced from the center) is inserted, the speed may becomeslower if there are large vibrations while the disk is rotating.*9 Depending on the disk, the writing speed may become slower.*10 A 16,777,216 color display is achieved by using the dithering function.*11 Display may be impossible using some connected external displays.*12 Some devices cannot be used depending on the port type.*13 Operation has been confirmed for Panasonic SD memory cards with up to 2 GB capacity. The transfer rate using the SD memorycard slot on this computer is 8 MB per second (this is a theoretical value, and differs from actual speeds). The transfer rate is 8MB per second even if you use an SD memory card that supports high-speed transfer rates. Does not guarantee connection/operation of all SD devices. Does not support MultiMedia card. Do not insert MultiMedia card.*14 Only a RAM module designed for DDR2 (PC2-3200) can be added (Panasonic : CF-BAV0256U / CF-BAV0512U).JEDEC standard 214 pin Micro DIMM cannot be used. PC2100 / PC2700 172 pin Micro DIMM cannot be used.*15 Does not guarantee operation of all USB-compatible peripherals.*16 The AC adaptor is compatible with power sources up to 240 V AC adaptor. This computer is supplied with a 125 V AC compatible AC cord.*17 Varies depending on the usage conditions, CPU speed, etc. Measured value when the power saving function on the USB2.0 USBRoot Hub is set to on.
