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 as 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. 6

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 as 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.
