![8Getting StartedPrecautions (Battery Pack)NOTEThe battery pack may become warm during rechargingor normal use. This is completely normal.Recharging will not commence outside of the allowabletemperature range (0 °C to 50 °C {32 °F to 131 °F}).( “Battery Power”) Once the allowable rangerequirement is satisfied, charging begins automatically.Note that the recharging time varies based on the usageconditions. (Recharging takes longer than usual whenthe temperature is 10 °C {50 °F} or less.)If the temperature is low, the operating time is short-ened. Only use the computer within the allowable tem-perature range.This computer has a high temperature mode functionthat prevents the degradation of the main battery in hightemperature environments. If the high temperature modeis enabled in the Setup Utility ( “Setup Util-ity”), a level of 100% in the [High Temperature] modeis about a level of 80% in the [Normal Temperature]mode.The battery pack is a consumable item. If the amount oftime the computer can be run off a particular battery packbecomes dramatically shorter and repeated rechargingdoes not restore its performance, the battery pack shouldbe replaced with a new one.When transporting a spare battery inside a package, brief-case, etc., it is recommended that it be placed in a plasticbag so that its contacts are protected.Always power off the computer when it is not in use.Leaving the computer on when the AC adaptor is notconnected will exhaust the remaining battery capacity.Care should be exercised with regard to the following inorder to avoid the possibility of overheating, fire or damage.Avoid HeatDo not throw the battery pack into a fire or ex-pose it to excessive heat.Keep Articles AwayDo not place the battery pack together with articlessuch as necklaces or hairpins when carrying or stor-ing.Do Not DisassembleDo not insert sharp objects into the battery pack,expose it to bumps or shocks, deform, disassemble,or modify it.Do Not ShortDo not short the positive (+) and negative (-) con-tacts.Avoid Extreme Heat, Cold and Direct SunlightDo not charge, use or leave the battery pack forextended periods where it will be exposed to di-rect sunlight, in a hot place (in a car on a sunnyday, for example), or in a cold place.Do Not Use With Any Other ComputerThe battery pack is rechargeable and was intendedfor the specified computer. Do not use it with acomputer other than the one for which it was de-signed.Do Not Put into a MicrowaveDo not put the battery pack into a microwave ovenor a pressurized chamber.Stop UsingShould the battery emit an abnormal odor, becomehot to the touch, become discolored, change shape,or become in any way different from normal, re-move it from the computer and stop using it.If the battery pack will not be used for a long period of time(a month or more), charge or discharge (use) the battery packuntil the remaining battery level becomes 30% to 40% andstore it in a cool, dry place.This computer prevents overcharging of the battery by re-charging only when the remaining power is less than approx.95% of capacity.The battery pack is not charged when the computer is firstpurchased. Be sure to charge it before using it for the firsttime. When the AC adaptor is connected to the computer,charging begins automatically.Should the battery leak and the fluid get into your eyes, do notrub your eyes. Immediately flush your eyes with clear waterand see a doctor for medical treatment as soon as possible.Do not touch the terminals on the battery pack. The batterypack may no longer function properly if the contacts are dirtyor damaged.Do not expose the battery pack to water, or allow it to be-come wet.Read Me FirstCablesUse of an interface cable longer than 3 m (9.84 feet) is notrecommended.PeripheralsIncorrectly using peripheral devices may lead to a decrease inperformance, an increase in temperature and/or damage yourcomputer. For more information on peripheral devices, refer tothe Reference Manual.](https://usermanual.wiki/Panasonic-of-North-America/9TGCF-735.User-Manual-for-CF-73/User-Guide-401445-Page-8.png)
![9Getting StartedWhen Using Peripheral DevicesPay strict attention to the following points to avoid damage to the computer, peripheral devices, cables, etc.Also, in addition to following this manual and the Reference Manual, carefully read the instruction manuals forthe peripheral devices being used.Use only peripheral devices that conform to the computer’s specifications.Connect the devices properly, paying close attention to the condition and position of the connectors.If a connection cannot be made easily, do not apply undue force; check once more to confirm the conditionand position of the connector (alignment of pins, etc.) .If the connector has holding screws, fasten the screws firmly.Do not carry the computer with cables attached, and do not pull on the cables forcefully.Saving Data on the Hard DiskHard Disk LockWhen the Hard Disk Lock is set to [Enable], it is impossible to read/write data from/to the hard disk when the harddisk is installed in a different computer, since a password is also set for the hard disk. When the hard disk isreturned to the original computer, you can read/write data as before. In this case, however, make the settings in theSetup Utility exactly the same as they were before the hard disk was removed. (Note that this Hard Disk Lockdoes not guarantee the complete protection of data. “Security Measures”)When Disposing of or Transferring Ownership of This DeviceWhen disposing of or transferring ownership of this device, erase all data on the hard disk in order to prevent thetheft of hard disk data. Even if you delete data or initialize the hard disk through normal Windows commands, datacan still be read using special software. In order to erase all data, either have the data erased by a specialist (at acharge) or use the hard disk data erase utility (included) ( page 31). (Note that this hard disk data erase utilitydoes not guarantee that data will be completely erased.)Also, note that if you transfer ownership of this device without deleting commercial software that you haveinstalled to the hard disk, you may be in violation of the licensing agreement for that software.Do not expose your computer to shock.Use care when handling your computer, shock may damage your hard disk or make your software applica-tions and data unusable.Do not power off your computer while software applications are running or hard disk drive indicator ( ) is on.Properly shut Windows* down to avoid problems.Save all valuable data to disks.Backing up data to disks will limit damage should trouble occur to your computer or should you inadvert-ently change or erase data.Use the security function for all important data. ( “Security Measures”)*Windows 2000 : This computer uses Microsoft® Windows® 2000 Professional.Windows XP : This computer uses Microsoft® Windows® XP Professional.Users are advised to purchase the latest versions of virus protection software and use them regularly.We recommend you run the software:• After booting your computer.• After receiving data.We recommend that you check data received on disks or from external sources, such as data downloaded fromthe Internet, e-mail, etc. (For compressed files, uncompress them before running a check).Computer VirusesWireless LANTo prevent theft of data or unauthorized access to the hard disk via a wireless LANIf you plan to use wireless LAN functions, we recommend that you do so only after making the appropriatesecurity settings, such as for data encryption.](https://usermanual.wiki/Panasonic-of-North-America/9TGCF-735.User-Manual-for-CF-73/User-Guide-401445-Page-9.png)


![12Getting StartedConnect your computer to a power outletCAUTIONBe sure the AC adaptor is connected until completing Step 7.When using the computer for the first time, do not connect any peripheral de-vice except the battery pack and AC adaptor to the computer.Handling the AC adaptorDo not twist or pull the AC power cord forcefully.
