■ Precautions for radio signals

● The wireless LAN card WLI2-CF-S11has been approved for conformity

to the engineering standards as the wireless facility for a radio station
with the low power data communication system based on the Wireless
Telegraphy Act. Therefore, use of this LAN card does not require any
radio station license.

● Never use the WLI2-CF-S11 near the magnetic field around a

microwave oven or in an area where static electricity and/or radio noise is
generated. The radio signals may not be normally transmitted in these
areas.

* When the WLI2-CF-S11 is used near a wireless printer buffer

(BUFFALO's RYP-G or similar products by other manufacturers) that
use radio signals around 2.4 GHz, the processing speed of both
devices may be adversely affected.

● As the WLI2-CF-S11 has been approved for conformity to the

engineering standards, the following may be regarded as unlawful.

• Disassembling/remodeling the WLI2-CF-S11

• Removing the approval label from the rear of the WLI2-CF-S11

● When it is necessary to set a radio channel other than the initial setting in

the WLI2-CF-S11, use the same frequency band as the following
equipment or wireless stations

• Industrial, scientific, or medical equipment

• Radio station for mobile identification used such as on a manufacture
line in a factory

① On-premise radio station (requiring a license)
② Specific low power radio station (requiring no license)

● Operating the WLI2-CF-S11 may cause interference with the above

equipment or radio stations. Thus, take precautions for the following
points

1 Before using the WLI2-CF-S11, verify that no on-premise radio

station for mobile identification or no specific low power radio
station is operating near the WLI2-CF-S11.

2 If an event of interference should be taken place by the WLI2-CF

-S11 with an on-premise radio station for mobile identification,

immediately change the frequency for this product to prevent the
interference.

3 If you notice any trouble such as an event of interference caused by

the WLI2-CF-S11 with a specific radio station for mobile
identification, contact your nearest sales representative.

■ WEP (Wired Equivalent Privacy) - Recommendation

of Encryption

Since the wireless LAN card communicates using radio waves, radio
packets could be intercepted and analyzed outside. To ensure transmission
security, it is recommended to set a password called 'WEP' in the radio
packets during communication.

This card allows two types of WEP; 40-bit WEP and 128-bit WEP. Setting
128-bit WEP (13 alphabetic characters or 26 hex digits) assures higher
security. However, when communicating with a wireless LAN product
compatible only with 40-bit WEP (5 alphabetic characters or 10 hex digits),
it is necessary to set the 40-bit WEP in this product.

※ For the WEP (encryption) setting in the AirStation, refer to the manual

included in the AirStation.
