Supported BLUETOOTH version and
profiles

Profile refers to a standard set of functions
for various BLUETOOTH product features.
See “BLUETOOTH section” in
“Specifications” (page 37) for the
BLUETOOTH version and profiles supported
by this receiver.

Effective communication range

BLUETOOTH devices should be used within
approximately 10 meters (33 feet)
(unobstructed distance) of each other. 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

• Locations where a wireless LAN is

installed

• Around microwave ovens that are in use

• Locations where other electromagnetic

waves are generated

Effects of other devices

BLUETOOTH devices and wireless LAN
(IEEE 802.11b/g/n) device 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:

• Use this receiver at least 10 meters

(33 feet) away from the wireless LAN
device.

• Turn off the power to the wireless LAN

device when using your BLUETOOTH
device within 10 meters (33 feet).
