Phone List
Update.
The audio system searches for suitable
Bluetooth
® telephones within range
and enters them in the telephone list.
Authorized Bluetooth
® telephones will
be identified by a telephone-symbol in
front of the list entry once the tele-
phone list has been updated. (The sym-
bol will be grayed out if the authorized
phone is not located in the Bluetooth
®
range.)
iOn certain telephones, not only do you have
to activate the Bluetooth® function but your own
device must additionally be made “visible” for
other devices.
Each Bluetooth
® device has a Bluetooth® device
name. It is recommended to give your telephone
a personal name, by which you can clearly recog-
nize your telephone.
iIf the Bluetooth® function on the audio sys-
tem is disabled, the message
Bluetooth not
activated in system settings
appears.
iThe duration of the search procedure de-
pends on the number and type of Bluetooth®
telephones. The search may take a few minutes.
iIf the telephone list is already full (15 en-
tries), you must de-authorize one of the autho-
rized devices. Then you will start the search
again. Otherwise a new device you are looking
for will not appear in the list.
If the audio system does not find your phone, ex-
ternal authorization may be necessary
(
