39 Getting StartedUseful InformationTroubleshootingAppendix*6 Data transfer speeds indicate values measured byPanasonic Corporation. The data transfer rate of DVD per 1Xspeed is 1,350 KB/s. The data transfer rate of CD per 1Xspeed is 150 KB/s.*7 Performance of CD-R, CD-RW, DVD-RAM, DVD-R, DVD-RDL, DVD-RW, +R, +R DL, and +RW cannot be guaranteeddepending 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/+R DL (dual layerdiscs) and Ultra-Speed CD-RW. Does not support 2.6 GBDVD-RAM.*8 If an unbalanced disc (e.g., a disc with which the balancehas been displaced from the center) is inserted, the speedmay become slower if there are large vibrations while thedisc is rotating.*9 Only non-cartridge type or removable cartridge type can beused.*10 DVD-R is compatible with 4.7 GB (for General) playback.DVD-R (for Authoring) playback is compatible with discsrecorded using Disc-at-Once recording.*11 Depending on the disc, the writing speed may becomeslower.*12 Does not support writing to High Speed +RW.*13 A 16,777,216 color display is achieved by using the ditheringfunction.*14 Display may be impossible using some connected externaldisplays.*15 Only for model with wireless LAN.*16 Only for model with Bluetooth.*17 Some devices cannot be used depending on the port type.*18 Only for model that supports TPM.For information on TPM, click (Start) and input“c:\util\drivers\tpm\README.pdf” in [Start Search], and pressEnter, and refer to the Installation Manual of “TrustedPlatform Module (TPM)”.*19 This slot is compatible with High-Speed Mode. Operation hasbeen tested and confirmed using Panasonic SD/SDHCMemory Cards with a capacity of up to 32 GB.Operation on other SD equipment is not guaranteed.*20 Only a RAM module designed for DDR2 (PC2-5300) can beused (Panasonic : CF-BAK1024U, CF-BAB2048U).172 pin Micro DIMM used in CF-T5/CF-W5 series cannot beused.*21 Does not guarantee operation of all USB-compatible periph-erals.*22 Use a condenser-stereo microphone.*23 The AC adaptor is compatible with power sources up to240 V AC adaptor. This computer is supplied with a 125 VAC compatible AC cord. 20-M-1-1*24 Measured using MobileMark™ 2007 (LCD brightness :60 cd/m2 ).Varies depending on the usage conditions, or when anoptional device is attached.When Economy Mode (ECO) is enabled, the operating timebecomes approximately 20% shorter than when it is dis-abled.When using the optional battery pack (CF-VZSU52W), oper-ating time will be almost halved.*25 Varies depending on the usage conditions, CPU speed, etc.It may take a long time to charge a fully discharged battery.When using the optional battery pack (CF-VZSU52W) :Approx. 4 hours (Power off)/Approx. 5 hours (Power on)*26 Approx. 0.9 W when the battery pack is fully charged (or notbeing charged) and the computer is off. V AC>Even when the AC adaptor is not connected to the computer,power is consumed (Max. 0.5 W) simply by having the ACadaptor plugged into an AC outlet.*27 Rated power consumption. 23-E-1*28 Average value. May differ depending on models.*29 Operations of this computer are not guaranteed except forthe pre-installed OS and the installed OS by using the Prod-uct Recovery DVD-ROM (included).Some parts of the software in the Product Recovery DVD-ROM may not be installed depending on a model.*30 Must be installed before use.*31 Only for model that supports TPM.Must be installed before use.*32 Only for model with fingerprint reader.Must be installed before use.*33 The Product Recovery DVD-ROM is required.*34 For startup methods, refer to “Hardware Diagnostics”(Î page 32).*35 These are speeds specified in IEEE802.11a+b+g+n stan-dards. Actual speeds may differ.
