Notes When Using a Wireless LAN

International Travel Precautions
Wireless LAN units are based on the specifications of the country of
purchase.
The wireless LAN unit is designed to conform to the channel and
frequency limits of the country it is intended to be used in. If the wireless
LAN unit is used outside the country of purchase, check with a local
dealer for more information.
Wireless Telegraphy Act Regulations
The following acts are prohibited by the Wireless Telegraphy Act.
•
Modifying and disassembling (including the antenna)
•
Removing the label of conformance
•
IEEE 802.11a (5 GHz band) external use
Notes on Security when Using Wireless LANs
(Important information on customer rights (maintaining privacy))
The advantage of using a wireless LAN over a LAN cable is that, because
information is exchanged using radio signals, you can easily connect to
the network if you are within range of the radio signals.
A disadvantage of this is that within a certain range, the electromagnetic
signals can pass through barriers such as walls, so that if security
countermeasures are not implemented in some way, problems such as the
following may occur.
•
Communicated data can be intercepted
A third party may be able to receive wireless transmissions without
authorisation, and they could obtain personal information from these
transmissions such as IDs, passwords, or credit card numbers, or they
could intercept the contents of personal e-mail messages.
•
Unauthorised access to the network
A third party could access an individual or intra-company network
without permission and carry out any of the following activities.
•
Retrieve personal data or other secret information (information
leakage)
•
Pose as another user and send inappropriate data (impersonation)
•
Overwrite the contents of intercepted data and resend it
(falsification)
•
Introduce a computer virus which could cause data loss or system
crashes (damage)
Initially, the possibility that such problems could occur through settings
concerning the security of the wireless LAN product and by using the
product are decreased, because the wireless LAN card and the access
point have security measures to deal with these problems. We recommend
that you use this product after making security settings using your own
judgment and assuming full responsibility, and with your full
understanding of problems that may occur if you do not make any security
settings.
