FCC Radiation Exposure Statement
The available scientific evidence does not show that any health problems are associated
With using low power wireless devices. There is no proof, however, that these low
power wireless devices are absolutely safe. Low power Wireless devices emit low
levels of radio frequency energy (RF) in the microwave range while being used.
Whereas high levels of RF can produce health effects (by heating tissue), exposure to
low level RF that does not produce heating effects causes no known adverse health
effects. Some studies have suggested that some biological effects might occur, but such
findings have not been confirmed by additional research. PC-MM20 has been tested
and found to comply with the Federal Communications Commission (FCC) guidelines
on radio frequency energy (RF) exposure. The maximum SAR levels tested for the PCMM20 has been shown to be W/kg at Body.

been disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
Wireless LAN Precautions
• Disable the integrated antenna and do not communicate with wireless LAN in
specific environments where radio-susceptible equipment is nearby, on airplanes,
in hospitals, for example.
• Disable the integrated antenna and do not communicate with wireless LAN in
crowded places for prevention of cardiac pacemaker interference.
• Maintain a space of at least 8.66” (22cm) between a cardiac pacemaker and an
active wireless LAN antenna.
• Never disassemble or alter the wireless LAN unit.
• Do not remove the certification label on the wireless LAN unit.
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 card 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.
xi
PC Disposal or Transfer
Prior to the disposal or transfer of your computer, you should erase the data from
hard disks.
To remove the data from your hard disk drive, you will need to:
• “Delete” the data by placing it in your recycle bin.
• Empty the recycle bin.
• Format the hard drives.
• Recover the system.
The above procedures do not completely delete all data from your hard disks.
When a file is deleted, the disk location where it is stored is marked as unallocated
space available for new data. However, the old data is still there and can be recovered
unless new data is written. Because of the reason, malicious persons can recover the
“deleted” data and misuse it. To avoid the data spillage, users must thoroughly erase
all the data from the hard disks.
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
Be sure to delete the software, such as operating system(s) or applications, on your
hard disk when transferring your computer, 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.
(Data loss or alternation can be caused by: malfunction, repair or misuse of your
computer: improper change of the battery pack: damage by static electricity or
electrical noise.)
xii
• Your computer is integrated with a magnet on the right side of the display. Be sure
to keep magnetic cards and floppy disks away from the right side of your
computer to prevent the data on the cards or floppy disks from being erased.
Magnet
• This computer has a sensor on the right side of the keyboard that responds to the
magnet. If the magnet gets close to the sensor:
• The backlight will be turned off.
• The system may enter the standby or the hibernate mode depending on the
setting. (See Chapter 3.)
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.)
• Do not use your computer in an environment where sunlight or indoor lighting
reflects off the screen.
• Position the display slightly below eye level and give a space of 15.7” (40cm)
through 23.6” (60cm) between you and the display.
xiii
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 includes some security threats and can produce the situations mentioned below
without proper security settings.
• Eavesdropping
Malicious third parties can intercept the transmission and monitor your mail to
obtain 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 purchase.
All security features must be configured according to reference manuals of the
wireless LAN devices, which results in reduced opportunities for the situations
described above.
Use with a clear understanding that wireless LAN includes vulnerabilities that could
allow attackers to simply bypass security features.
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.
