12.3 Hands-free profile
Yet another operating option is the
hands-free profile
(HF profile) in
the
BT profiles
menu.
Note:
Please note that, with the selection of the
HF profile
,
using the BT technology will increase the battery discharge
rate of your mobile and therefore reduce the number of
operating hours.
In the
HF profile
, the connection is established via the GSM network
of your mobile. The name of your network operator will, however, only
be displayed on the mobile.
Incoming calls are displayed on the Twin-Phone. The mobile phone ring
tones and the Twin-Phone will also sound. The same applies to inco-
ming SMS.
Apart from the SMS function, all other main menu functions are availab-
le when the
HF profile
is selected. When using the phone book, you
can only access the
internal phone book
. The
external phone
book
function is not available.
The
HF profile
also provides the option to disconnect any connection
between the Twin-Phone and mobile via the menu of your mobile pho-
ne.
12.4 Auto profile
In the
auto profile
, the Twin-Phone independently selects a profile.
The Twin-Phone will search for options to establish a connection in the
following order: first, it will check whether a SIM card has been inserted
in the integrated card slot. Then, it will search for an option to establish
a connection using the SAP technology. Finally, it will check whether it
is possible to establish a connection in the
HF profile
.
If a SIM card is inserted in the Twin-Phone, the
auto profile
will auto-
matically open the
SIM card profile
and will stop searching.
It is advisable to select the
auto profile
if, for example, a user with an
SAP-compatible mobile and another with an HFP-compatible mobile use
the Twin-Phone in turn. The pre-selected
auto profile
will automati-
cally enable the suitable profile after the phone is switched on.
If only one person uses the Twin-Phone, they choose their preferred
profile (
SIM card, SAP profile
or
HF profile
), which will be enabled
every time the phone is switched on (unless the profile has been chan-
ged). In the future, this will allow a connection to be automatically es-
tablished between the Twin-Phone and the mobile once the devices
have been paired.
13. Bluetooth connections
You can access the menu
BT connections
in the main menu by pres-
sing the OK key. This submenu is required for pairing or connecting
your mobile with and/or to the Twin-Phone. Here, pairing means to
establish the very first connection through identification. The BT con-
nections menu comprises four submenus:
Establish BT connection,
Paired devices, Disconnect BT
and
Bluetooth setup
.
If you use your SIM card with the Twin-Phone, you will not need the
functions available in the
BT connections
menu. This function will not
be available when the SIM card is inserted.
Note:
For security reasons, it is not possible to pair your mo-
bile phone with and/or establish a new connection to the
Twin-Phone via your mobile’s menu. This is the only way to
ensure that no other user within the same reception zone,
e.g. a passenger in certain traffic conditions (traffic jam),
can connect their mobile to your Twin-Phone.
13.1 Establishing a BT connection in HF profile
The submenu
Establish BT connection
indicates whether a BT con-
nection to a mobile was established. The
BT connections
menu will
only be enabled if you have activated the
HF profile
or
SAP profile
via the Twin-Phone menu
BT profiles
.
Pairing
Use this submenu for pairing the phone with another BT device. This
means that both devices will detect the respective identifier signal of its
respective counterpart to automatically establish a connection in the
future.
a) Select
Establish BT connection
in order to pair the Twin-Phone
with your mobile.
