Security Precautions when Using Wireless LAN (If
equipped)
Wireless LAN allows information to be exchanged between wireless access points instead of using a network cable,
which offers the advantage that a WLAN connection can be established freely within an area in which radio waves can
be transmitted.
On the other hand, the following problems may occur if security settings are not configured, because radio waves can
pass through obstacles (including walls) and reach everywhere within a certain area.
Secretly Viewing Communication Contents
A third person with malicious objectives may intentionally monitor radio waves and gain unauthorized access to the
following communication contents.
• Personal information including ID, passwords, and credit card numbers
• Contents of email messages
Illegal Intrusion
A third party with malicious intent may gain unauthorized access to personal or company networks and conduct the
following illegal actions.
• Extracting personal and confidential information (information leak)
• Entering into communication while impersonating a specific person and distributing unauthorized information
(spoofing)
• Modifying and retransmitting intercepted communications (falsification)
• Transmitting computer viruses and destroying data and systems (destruction)
Wireless LAN cards and wireless access points contain built-in security mechanisms to address these problems and to
reduce the possibility of these problems occurring by configuring the security settings of wireless LAN products when
the product is used.
We recommend that customers take responsibility and use their judgment when configuring the security settings and
that they ensure that they fully understand the problems that can occur when the product is used without configuring the
security settings.
