When Using a Wireless LAN
A wireless LAN (WLAN) uses radio waves
for transmission, and thereby has the
benefit of allowing a LAN connection
anywhere in an area reachable by radio
waves. Conversely, eavesdropping by a
third party or wrongful intrusion are
possible if security settings are not
configured. Users are recommended to
use discretion and configure security
settings before using.
Wireless LAN
Do not use wireless LAN near magnetic
devices such as electrical appliances or AV/OA
devices, or in radio waves.
•
Magnetism or radio waves may increase
noises or disable communications (especially
when using a microwave oven).
•
When used near TV, radio, etc., reception
interference may occur, or channels on the
TV screen may be disturbed.
•
If there are multiple wireless LAN access
points nearby and the same channel is used,
search may not work correctly.
Frequency band
The frequency band used by the WLAN device
is indicated on a label in the battery pack
recess of the terminal. The following figure
explains the indications on the label.
① ② ③ ④
⑤
①
2.4
: This radio equipment uses the
2400 MHz band.
②
DS
: Modulation scheme is the DS-SS
system.
③
OF
: Modulation scheme is the OFDM
system.
④
4
: The estimated interference
distance is 40 m or less.
⑤
: The full band between
2400 MHz and 2483.5 MHz is
used and the band of the mobile
identification device can be
avoided.
•
Available channels vary depending on the
country.
•
For use in an aircraft, contact the airline
beforehand.
•
For use of WLAN in a foreign country, the
country may have limitations on such as
frequencies and locations where you can use
it. Before using WLAN in a foreign country,
confirm the available frequencies, laws,
regulations, and other conditions for use of
WLAN of the country.
