This device must accept any interference that may cause undesired operation.
NOTE:The radiated output power of the wireless network device is far below the FCC radio
frequency exposure limits.
Nevertheless, wireless network device should be used in such a manner that potential
for human contact during normal operation is minimized.
In according with 47 CFR Part 15.407(e) U-NII devices operating in 5.15 - 5.25 GHz frequency
bands are restricted to indoor operations only.
This transmitter must not be co-located or operated in conjunction with any other anernna
transmitter.

Notes on security in use of wireless LAN products
The wireless LAN is advantageous to allow LAN connection freely within the radio wave range
because data is transmitted among wireless access points including computers through radio
waves instead of using LAN cables.
On the other hand, since radio waves reach any locations over obstacles (including walls)
within a certain range, the following problems may occur without security.

Stealing communication data
Malicious outsiders may intentionally intercept radio waves to steal communication
data as follows:

Personal information including IDs, passwords and credit card numbers

Mail contents
Invading into network illegally
Malicious outsiders may access to personal and corporate networks without notice to
take the following actions:

Acquiring private and confidential information (information leak)

Make communication as a specific person to spread illegal information (spoofing)

Rewrites intercepted communication data to be transmitted (falsification)

Spread computer virus to destroy data and/or systems (destruction)
Security-related setting to address the above issues is provided for wireless LAN cards and
wireless access points of this product. It is recommended to use the product with the security
setting at your discretion and under your own responsibility after thoroughly understanding the
possible outcome if no security setting is made.
