Reception interference caused by
Bluetooth devices

(IEEE802.11b/g/n) devices use the same
frequency band (2.4GHz). If you use
Bluetooth devices near a wireless LAN
device, reception interference may occur or
the communications speed may lower.
Also, you may hear noise or have a
connection problem. Communication may
be interrupted or sound may be lost while
streaming data, etc. In these cases, do the
following:
･
Keep the terminal and Bluetooth device
to be connected wirelessly 10 or more
meters away from a wireless LAN device.
･
Within 10 meters, turn off the Bluetooth
device to be connected.
