Wireless LAN (WLAN)
■ Wireless LAN (WLAN) uses radio waves to
enable communications between compatible
devices, thus allowing connection to a local
area network from anywhere within range.
However, there is a risk of data interception
by malicious third parties unless security is
established. Users are advised to assess
their responsibilities and accordingly
configure security settings.
• 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 wireless LAN
function of this terminal is indicated on a label
in the battery compartment of the terminal. The
following explains the indications on the label.
2.4/DS4/OF4
2.4
: This radio equipment uses the
2400 MHz band.
DS
: Modulation scheme is the
DS-SS system.
OF
: Modulation scheme is the
OFDM system.
4
: The estimated interference
distance is 40 m or less.
: 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.
When using WLAN overseas, check the
available frequency band, laws, regulations or
other conditions of the country beforehand.
For use in an aircraft, contact the airline
beforehand.
