Telephone - Mercedes-Benz 212 Sedan E-Class Service Manual

Telephone

Suitable mobile phones can be connected to the
vehicle's audio system via the standard Bluetooth
interface in vehicles with basic telephony, or via a
universal interface in vehicles with the optional
comfort telephony, code (386) (suitable mobile
phones must support the Hands Free Profile (HFP) 1.0
or 1.5).
In both variants the mobile phone can be operated
from the multifunction steering wheel and via the
buttons on the relevant audio unit.
Basic telephony via Bluetooth interface
During Bluetooth operation, the mobile phone is not
connected to the external vehicle antenna and is not
recharged.
There is read access to the phone book of the mobile
phone if it supports the Bluetooth Phonebook Access
Profile (PBAP). Otherwise the entries in the phone
book of the mobile phone can only be transferred to
the audio unit by means of business cards.
Shutdown behavior
The mobile phone cannot be switched on or off via
Bluetooth. The mobile phone remains on even when
the data bus is idle. Calls are ended when the ignition
key is removed, in order to ensure that any connec-
tions continuing unnoticed are terminated.

Comfort telephony via universal
interface
The universal interface is located in the center console
and connects the mobile phone to the vehicle via a
suitable cradle. Integrating the mobile phone into the
on-board electrical system via the cradle has the
advantage that the external vehicle antenna can be
used and the battery of the mobile phone can be
recharged by the on-board electrical system.
Operating the phone via the universal interface allows
the phone book to be transferred to the audio unit. The
entries can be downloaded both from the memory of
the mobile phone and from the SIM card.
Shutdown behavior
The shutdown behavior of a plugged-in mobile phone
when the ignition key is removed depends on the
behavior of the cradle associated with it. Generally,
new cradles do not shut down.

behavior can be found at:
