Network Connection Procedure

International Travel Precautions

The wireless LAN card configuration is based on the specifications of the country
of purchase.
Wireless LAN cards have limitations on the channel
they can use, and so you may need to be aware of this if using the wireless LAN
card that is included with the projector in countries other than the country of
purchase.

Notes on Security when Using Wireless LANs

(Important information on customer rights (maintaining privacy))
Because wireless LANs use electromagnetic signals instead of a network cable to
send and receive data, they have the advantage of allowing a device to connect to
the network easily as long as they are within range to receive the 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 followings may occur.
• Communicated data can be intercepted
A third party may be able to receive wireless transmissions without authorisation,
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.
• Unauthorised 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)
Nowadays, wireless LAN cards and wireless access points are equipped with
security measures that address such security problems, so that you can enable
security-related settings for wireless LAN products in order to reduce the likelihood
of problems occurring.
