Introduction
Radio frequencies
The radio frequencies for the Bluetooth function of the FOMA
t
erminal are as f
ollows:
2.4 FH 1
2.4 : Indicates radio facilities that use 2400 MHz
frequencies.
FH : Indicates modulation is t
he FH
-
SS system.
1 : Indicates t
hat an estimated interference distance is 10
meters or less.
: Indicates that all radio frequencies 2400 MHz through
2483.5 MHz are used, and t
hat the frequencies for
mobile object identifiers shall not be avoided.
Cautions on Using Bluetooth Devices
Bluetooth operates at radio f
requencies assigned to the
in
-
house radio stations f
or mobile object identifiers that have
to be licensed and are used in production lines of
a factory,
specific unlicensed low power
radio stations, and amateur radio
stations (hereafter, referred to “another radio station”) in addition
to scientific, medical, industrial devices, or
home electric
appliances such as microwave ovens.
1. Before using t
his product, make sure that “another radio
station” is not operating nearby.
2. If radio interference between this product and “another radio
s
tation” occurs, move immediately t
o another place or turn off
power to avoid interference.

Notes on handling Wireless LAN (WLAN)
Wireless LAN
Do not use W
ireless LAN in a place where magnetized
by electric product, AV, OA equipment, etc. or where
e
lectromagnetic wave is generated.
⿠If magnetism or electrostatic noise affects your mobile phone,
n
oise may be increased or communication may not be available
(especially when using microwave oven, it may affect your
m
obile phone).
⿠Using near TV or radio may cause poor reception or TV screen
m
ay be disturbed.
⿠W
hen multiple wireless LAN access points exist near y
our
mobile phone and t
hey use the same channel, search may not
be performed correctly.
Radio frequencies
T
he radio frequencies for WLAN devices are written on battery
p
ack compartment of your mobile phone. Label description are
a
s follows:
2.4 DS/OF 4
2.4 : Indicates radio facilities that use 2400 MHz
frequencies.
DS/OF : Indicates modulation is t
he DS
-
SS/OFDM system.
4 : Indicates t
hat an estimated interference distance is 40
meters or less.
: Indicates that all radio frequencies 2400 MHz through
2483.5 MHz are used, and t
hat the frequencies for
mobile object identifiers shall be avoided.
To use on airplane, confirm with airline company
in advance.
