Precautions about Bluetooth
®
•
The Bluetooth
®
function of the product conforms to
the domestic standards of Japan and FCC standards
and EC directives, and has been certified.
•
The 2.4 GHz band used by wireless LAN (Wi-Fi
®
) and
Bluetooth
®
devices is shared 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
®
devices used.
