■ 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.
