capabilities for various BLUETOOTH
product capabilities. The unit supports
the following BLUETOOTH version
and profiles.
Supported BLUETOOTH version:
– BLUETOOTH Specification version
3.0

Note
• To be able to use the BLUETOOTH function,
the BLUETOOTH device to be connected must
support the same profile as the unit. Even if the
device supports the same profile, the functions
may differ depending on the specifications of
the BLUETOOTH device.
• The audio/music playback on the unit may be
delayed from that on the BLUETOOTH device
because of the characteristics of the
BLUETOOTH wireless technology.
Effective communication
range
BLUETOOTH devices should be used
within approximately 10 meters
(unobstructed distance).
The effective communication range may
become shorter under the following
conditions.
– When a person, metal object, wall or
other obstruction is between the
devices with a BLUETOOTH
connection

GB
– Locations where a wireless LAN is
installed
– Around microwave ovens that are in
use
– Locations where other electromagnetic
waves occur
Effects of other devices
BLUETOOTH devices and wireless
LAN (IEEE802.11b/g/n) use the same
frequency band (2.4 GHz). When using
your Bluetooth device near a device with
wireless LAN capability,
electromagnetic interference may occur.
This could result in lower data transfer
rates, noise, or inability to connect. If
this happens, try the following remedies:
– Connect the unit and a BLUETOOTH
device at least 10 m away from other
wireless LAN devices.
– Turn off the power to the wireless LAN
equipment when using your
BLUETOOTH device within 10 meters.
Effects on other devices
The radio waves from the unit may
interfere with the operation of some
devices. Since this interference may
result in malfunction, always turn off the
power on the unit and the BLUETOOTH
device in the following locations:
– In hospitals, on trains, in airplanes, at
gas stations, and any place where
flammable gasses may be present
– Near automatic doors or fire alarms
Notes
• The unit supports security functions that comply
with the BLUETOOTH specification to ensure
secure connection during communication using
BLUETOOTH wireless technology. However,
this security may be insufficient depending on
the setting content and other factors, so always
be careful during communication using
BLUETOOTH technology.
