Introduction
Wireless LAN (WLAN) uses radio waves to
communicate information. Therefore, it has
an advantage of freely connecting to the LAN
within the service area. On the other hand, if
security setting is not set, it is possible for a
malicious third party to intercept the
communication contents or hack. It is
recommended to set security setting at your
own risk and judgement.
Wireless LAN
Do not use wireless LAN near magnetic devices
such as electric 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.
Radio frequencies
The radio frequencies the WLAN-installed
devices use are indicated on the battery
storage section. The following are the
descriptions:
①
2.4: This radio equipment uses the 2400 MHz
band.
②
DS: The modulation system is the DS-SS
system.
③
OF: The modulation system is the OFDM system.
④
4: The estimated coverage distance is 40 m or
less.
⑤
: All radio frequencies
between 2400 MHz and 2483.5 MHz are used
and the frequencies for mobile object identifiers
shall not be avoided.
Available channels vary depending on the country.
For use in an aircraft, contact the airline beforehand.
There are restrictions on the use of wireless LAN in
some countries or regions such as France. If you
intend to use Wi-Fi overseas, check the local laws
and regulations beforehand.

Cautions on using 2.4 GHz devices
WLAN-installed devices operate at radio
frequencies assigned to the in-house radio
stations for a mobile object identifier (radio
stations requiring a license) used in
production lines of a factory, specific
unlicensed low power radio stations (radio
stations requiring no license), and amateur
radio stations (radio stations requiring a
license) in addition to industrial, scientific,
medical devices or home electric
appliances such as microwave ovens.
1. Before using this device, make sure that
the in-house radio stations for a mobile
object identifier, specific unlicensed low
power radio stations and amateur radio
stations are not operating nearby.
