Introduction
・
Wireless LAN
Do not use Wireless LAN in a place where magnetized by electric products, AV, OA
equipment, etc. or where electromagnetic wave is generated.
- If magnetism or electrostatic noise affects FOMA terminal, noise may be
increased or communication may not be available (especially when using
microwave oven, it may affect the terminal).
- Using near TV or radio may cause poor reception or TV screen may be blurred.
- When multiple wireless LAN access points exist near FOMA terminal and they
use the same channel, search may not be performed correctly.
・
Frequency bands
Frequency bands for WLAN devices are written on battery pack insert section of
phone. Label description are as follows.
a
2.4 : Radio equipment that uses the 2400 MHz band.
b
DS : The modulation is the DS-SS method.
c
OF : The modulation is the OFDM method.
d
4 : The expected interference distance is 40 m or shorter.
e
: All bandwidths between 2400 MHz and 2483.5 MHz are
used, and the bandwidth used by mobile object identification devices cannot
be avoided.
To use wireless LAN in FOMA terminal in 5.2/5.3 GHz, do not use outside because
of Radio Law.
Available channel varies by countries.
To use in airplane, confirm with airline company in advance.
Cautions on using 2.4GHz devices
In the bandwidth used by WLAN devices, in addition to home electric
appliances such as a microwave oven and industrial/scientific/medical devices,
in-plant radio stations for identification of mobile objects used in production
lines of a factory (a license is required), specified low power radio stations (a
license is not required), or amateur radio stations (a license is required) can be
in operation.
1. Before using this device, confirm that in-plant radio stations for
identification of mobile objects, specified low power radio stations or
amateur radio stations are not in operation in your neighborhood.
2. If this device generates harmful radio wave interference against in-plant
radio stations for identification of mobile objects, change the using
frequency promptly or stop using wireless LAN function, and contact
"General Inquiries" on the last page of this manual, then consult about
treatment for prevention of the interference (for example, installation of
partitions etc.).
3. In addition, if you have any problems such as this device generates radio
wave interference against specified low power radio stations for
identification of mobile objects or amateur radio stations, etc., contact
"General Inquiries" on the last page of this manual.
・
FeliCa reader/writer function of FOMA terminal uses weak waves requiring no
licenses for radio stations.
・
It uses 13.56 MHz frequency band. When using other reader/writers in your
surroundings, keep FOMA terminal away sufficiently from them. Before using
the FeliCa reader/writer, confirm that there are no radio stations using the same
frequency band nearby.
・
FM transmitter of FOMA terminal uses weak waves requiring no licenses for
radio stations.
