audio
device, it is connected automatically. Con-
nection involves first searching for a Blue-
tooth ®
audio device and then authorizing it.
You can authorize up to fifteen Bluetooth ®
devices.
i If you authorize a mobile phone that sup-
ports Bluetooth ®
audio, the A2DP and
AVRCP Bluetooth ®
audio profiles are con-
nected automatically.
The mobile phone is then entered:

supports two Bluetooth ®
profiles at the
same time, COMAND functions may
behave as follows:
R when connecting to the Internet, play-
back is stopped on the Bluetooth ®
