TM-P60 Technical Reference Guide
• Other equipment that uses the same frequency band used by the Radio Frequency
module that can be installed in this product includes equipment for industry, science
and medical treatment, microwave ovens, HomeRF, and radio and other broadcasting
equipment (both ones that require a license and ones that do not require a license).
• Confirm that radio and other broadcasting equipment are not used nearby before using
this product.
• When trouble occurs, for example, if the Radio Frequency module causes problems such
as radio wave interference, consult your dealer.
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. Please also see “Wireless LAN Security”
in Appendix F.

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.
This product, the wireless LAN card, and the access point have security mechanisms to counter
these problems. If you use the security settings for this product, you can nearly eliminate these
problems.
In some cases, the wireless LAN equipment is not set up before it is sold to the user. Therefore,
to attempt to prevent security problems, always use all the security settings for the wireless
LAN equipment according to the manual.
