Note about security

This section describes security concerns when using a wireless LAN by using the Radio
Frequency module that can be installed in this product.

Security is important for the protection of the user's privacy

A wireless LAN has the advantage that information can be exchanged by using radio waves
instead of a cable. However, radio waves are not confined to a cable and can be received in a
fairly wide area and through obstacles such as walls, so if security is not used, the following
problems may occur.
Communication data can be received by stealth.
A third person can receive private communication data by intercepting the radio waves
intentionally. Such a person could receive items such as the following:
• Personal information, such a an ID and password or credit card number
• The contents of e-mail.
• Data which is communicated between the PC and printer.
Illegal access
A third person can access the network and cause damage such as the following:
• Personal information and secret information can be removed.
• Invalid information can be sent as if it were from a legitimate user of the network.
• Intercepted communication contents can be re-written and sent.
• Data and the system can be destroyed by an electronic virus.
