[Authentication] to confirm the radio frequencies the WLAN-installed
devices use. The followings are the descriptions:
①
① 2.4: This radio equipment uses the 2,400 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 2,400 MHz
and 2,483.5 MHz are used and the frequencies for mobile object
identifiers can be avoided.
Available channels for the handset's wireless LAN are between 1 and
13. Note that other channel access points cannot be connected.
Available channels may vary depending on the country.
For use in an aircraft, contact the airline beforehand.

z 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 low power radio stations (radio stations requiring no
license), and amateur radio stations (radio stations requiring a
license) in addition to industrial, scientific and 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 low power radio
stations and amateur radio stations are not operating nearby.
2. If the device causes harmful radio interference to the in-house
radio stations for a mobile object identifier, immediately
change the radio frequency or stop use, and contact the
number listed in "General Inquiries" on the last page for
crosstalk avoidance, etc. (e.g. partition setup).
3. If the device causes radio interference to specific low power
radio stations for a mobile object identifier or amateur radio
stations, contact the number listed in "General Inquiries" on
the last page for further details.
z Cautions on using 5 GHz devices
In the 5 GHz frequency band, three bands of 5.2 GHz/5.3
GHz/5.6 GHz band (W52/W53/W56) are available.
y W52 (5.2 GHz band/36, 40, 44, 48 ch)
y W53 (5.3 GHz band/52, 56, 60, 64 ch)
y W56 (5.6 GHz band/100, 104, 108, 112, 116, 120, 124, 128,
132, 136, 140 ch)
Using 5.2 GHz/5.3 GHz band wireless LAN (W52/W53) outdoors
is prohibited by the Radio Law.
