Use of wireless LAN may be prohibited in
some countries. Please confirm laws and
regulations applicable in the country/region
before use.
2.4 : Indicates radio facilities that use
2400 MHz frequencies.
DS/OF : Indicates modulation is the DS-SS
system.
4 : Indicates that an estimated
interference distance is 40 meters
or less.
: Indicates that all radio frequencies

■Cautions on Using 2.4 GHz Devices
The bandwidth of the WLAN devices is
assigned to the 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), in addition to home electric
appliances such as a microwave oven,
industrial/scientific/medical devices.
1. Before using this device, confirm that
inplant 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, immediately change the radio
frequency or stop using wireless LAN
function, and contact “docomo
Information Center” on the back page
of this manual, then consult about
treatment for prevention of the
interference (for example, installation
of partitions etc.).
3. If this device generates harmful radio
wave interference against in-plant radio
stations for identification of mobile
objects or amateur radio stations, or if
any trouble occurs, contact “docomo
Information Center” on the back page
of this manual.
■Do not use the modified FOMA terminal.
Using a modified FOMA terminal
infringes the Radio Law.
The FOMA terminals are granted technical
regulations conformity certification as the
specified radio equipment under the Radio Law
and bear a “technical conformity mark ” on
the nameplate as evidence of conformity.
Unscrewing the FOMA terminal and modifying
internal components void the technical
regulations conformity certification.
Do not use the FOMA terminal in this state,
which infringes the Radio Law.
■Take special care not to operate the
FOMA terminal while driving.
Holding a mobile phone in your hand while
driving is subject to a fine or other penalties.
However, this does not apply in unavoidable
circumstances when, for instance, responding
to someone who is sick or injured or when
maintaining public order.
