Product Conformance
The wireless LAN unit equipped with your computer is in conformance with federal
requirements. No license is required for use of the device.
Notice of Radio Interference
The wireless LAN unit equipped with your computer operates at 2.4GHz that is also
used for microwaves, science or medical devices, other similar radio stations
(hereafter called “other radio stations”), etc.
•Prior to using the wireless LAN function with your computer, confirm that no
“other radio stations” are operating nearby.
•If interference with “other radio stations” is experienced, change the current
channel set to your computer or move your computer. If it fails, stop operating your
computer.
PC Disposal or Transfer
Before you dispose or transfer your computer, you should erase the data from hard
disks.
To remove the data from the hard disk of your computer, you will need to:
•“Delete” the data by placing it in the Recycle Bin.
•Empty the Recycle Bin.
•Format the hard disk drives.
•Recover the system.
The above procedures do not completely delete all data from the hard disk drives.
When a file is deleted, the disk location where it was stored is marked as unallocated
space available for new data. It means that the old data is still there and can be
recovered. It allows for malicious persons to recover the “deleted” data and misuse it.
To avoid the data spillage, you must thoroughly erase all the data from the hard disks.

xii
The following measures are recommended for permanent data deletion:
•Use special software or paid services for thoroughly erasing data.
•Hammer, or strongly magnetize, the hard disk to destroy the stored data.
Before you transfer your computer, delete any software in your computer including
the operating system or applications to avoid conflict with the software agreement(s).
Other Precautions
•Periodic back-up copies of your important data should be made to protect your data
in the event of hard disk failure or loss of the data. Use other storage devices for the
backup.
For Your Health
•Take regular breaks of ten to fifteen minutes after every hour of continuously
viewing the screen to relieve your eyes.
•Adjust the brightness for comfortable viewing. (Brightness level of about 500 lux is
recommended.)
•Avoid using your computer in an environment where sunlight or indoor lighting
reflects off the screen.

Notice of Computer Security
The Windows operating system on this computer provides the Security Center, which
manages the security features of the computer. It provides the status of the following
security functions and enables you to change the settings.
•Firewall
•Automatic Updates
•Virus Protection
Be sure to confirm that the three functions are “ON” to ensure the safety of the
computer.
To open the Security Center, click start – Control Panel – Security Center.
Firewall
The firewall function blocks unauthorized connection to this computer through the
Internet or a network.
Automatic Updates
The automatic updates function periodically detects new security programs to be
installed and automatically installs them.
Virus Protection
The Norton AntiVirus software, which automatically checks the virus infection, is
preinstalled in this computer. To protect the computer against new viruses and other
security threats, the virus definition file of the software must be updated. The virus
protection function monitors whether the definition file is latest. On your computer
with the preinstalled Norton AntiVirus software, however, the software monitors the
definition file and notifies you when the file needs to be updated.
When the Windows setup is finished, be sure to complete the Norton AntiVirus
wizard and LiveUpdate to update the definition file. (You must establish the
connection to the Internet for the update.)
After completing the Norton AntiVirus wizard and LiveUpdate;
* The Virus Protection in the Windows Security Center always displays as ON
regardless of the definition file status. Since the preinstalled Norton Antivirus
software manages virus check on your computer, be sure to perform the
LiveUpdate.

xiv
* You can enable the LiveUpdate automatically to run and update the file if any
updates are detected. (Refer to the Virus Protection section in the Appendixes.)
* You will have the message “Your computer might be at risk” at the bottom right of
the screen when one of the Firewall and Automatic updates is set to OFF.

xv
Notice of Security with Wireless Devices
Wireless LAN provides data transfer by means of electric waves instead of LAN
cables between communicating devices such as personal computers and a wireless
LAN station. Wireless LAN has an advantage of simple and ubiquitous LAN
connection in the ranges where electric waves are available. Since electric waves can
penetrate through walls and reach everywhere, wireless LAN without proper security
settings includes some security threats and can produce the situations mentioned
below.
•Eavesdropping
Malicious third parties can intercept the transmission and monitor your mail to
steal personal information such as an identification number, password, and credit
card number.
•Intruding
Malicious third parties can connect to a personal or office network without
authorization and illegally perform the following:
•Obtaining access to confidential customer records or sensitive corporate
information (Information leakage)
•Faking the original information (Spoofing)
•Altering the monitored original data and transmitting (Falsification)
•Spreading computer viruses resulting in the destruction of data or systems
(Destruction)
Although wireless LAN cards and wireless LAN stations (Access Points) have
security measures against the threats above, no security settings may have been
configured at the time of your purchase.
All security features must be configured according to reference manuals of the
wireless LAN devices, which results in reducing vulnerability to the attacks described
above.
Use the wireless devices with a clear understanding that wireless LAN includes
vulnerabilities that could allow attackers to simply bypass security features.

xvi
Security measures are important for all users to understand for a safe use of wireless
LAN. SHARP encourages all users to configure the security settings with their own
judgment and responsibility.
