Precautions for Using a Wireless LAN

• Do not use a wireless LAN if there is electromagnetic interference from other equipment. Doing
so may cause an accident due to the other equipment malfunctioning from the electromagnetic
interference.
Wireless uses radio waves to exchange information instead of an Ethernet cable. The wireless LAN
radio waves pass through barriers such as walls within a fixed area, so the following problems may
occur:
Leak of Personal Information
• Information such as IDs, passwords, credit card numbers, and the contents of e-mails, etc.,
may be stolen by a third party.
Illegal Access to the Network
• Data and systems may be corrupted or manipulated by a virus.
• An imposter may access information illegally.
• Confidential information may be accessed illegally.
To minimize the possibility of these problems occurring, it is recommended to check the functions built
into the wireless LAN devices, such as the projector and wireless LAN access points, and to specify
security settings.
