Cautions Regarding Wireless LAN Connections

Because not all the combinations of the product and wireless LAN devices have been checked for operation, the
operation of the product in combination with all the wireless LAN devices is not guaranteed.

Cautions about Security

Important Cautions about Your Privacy Protection
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 authorization, 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.
Unauthorized 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)
Security Settings
The wireless LAN card and access point have a security settings function to deal with these problems. You can
reduce the possibility these problems will occur by performing security settings before use.
Even with security settings, there is a possibility the security can be breached using particular
methods.
We recommend that you have full understanding regarding security problems and perform security
settings at your own judgment and liability.
Security settings are performed immediately after purchase (Initial setting: WPA2-PSK).
Limitations
You cannot stop the transmission of radio waves. If you need to stop the transmission of radio waves, turn off
the TM printer.
