Notes on using Bluetooth
functions
■
Frequency band
Bluetooth functions of the au cell phones use frequencies
®
in the 2.4 GHz band ranging from 2.402 GHz to 2.480 GHz.
Bluetooth
This product uses the 2.4 GHz band.
FH-SS is used as the modulation scheme.
The interference distance is about 10 m
or less.
• The bands of mobile unit identification
devices cannot be avoided.
■
Precautions about Bluetooth
• The Bluetooth function of this product conforms to the
®
domestic standards of Japan, FCC standards, and EC
Directives, and has been certified.
• The 2.4 GHz band used by Bluetooth
by various other devices. For this reason, Bluetooth
device use technologies for minimizing effects from
other devices using the same radio frequency band. In
some cases, however, the communication speed and
connectable range may be decreased, or disconnection
may occur, due to interference by other devices.
• The communication speed and connectable range vary
depending on the distance between communication
devices, obstacles and the Bluetooth

■ Bluetooth
precautions
®
The frequencies used by the Bluetooth
product are in the 2.4 GHz band. In this frequency band,
other similar wireless stations, in-plant wireless stations
for mobile unit identification that require a license for use,
such as factory production lines, specific smallpower
wireless stations that do not require licenses, amateur
wireless stations (collectively called "other wireless
stations" from here on) are operated in addition to home
electrical appliances such as microwave ovens, devices for
industrial, scientific and medical devices.
1. Before using this product, make sure that "other wireless
stations" are not in operation nearby.
2. In the event that instances of radio wave interference
have occurred between this product and "other wireless
stations", immediately either relocate this product or stop
operation of the device (stop emission of radio waves).
3. If you are unclear on any points or are troubled by
anything, contact an au shop or Customer Service
Center.
