Important notes

Close the windows and reduce all out-
side noise as much as possible when
you use hands-free operation.

A brief disconnection from the cellular
network is not a malfunction, as this
can occur when the network switches
areas. The phone will automatically try
to sign on to a network again.

If the message “Locked. Please enter
code” appears, enter the unlock code
to enable all telephone functions
(page 96).

If a menu other than the telephone
menu is displayed on the COMAND
screen, the display will change if an
outgoing call is sent out via the multi-
function steering wheel.In the following situations, it is not possible
or not yet possible to use the telephone:

The telephone is already unlocked but
is not or not yet registered in the net-
work.
The message “No Service” appears.
The telephone will try to register into
an existing network. If the network is
available, the telephone will be ready
for use.
The above message also appears 
if the network is no longer available
due to weak signals

if you try to make a call (message
appears for 8 seconds)

The message “Telephone is being acti-
vated. Please wait.” appears.
COMAND prepares the telephone for
use. Select other system functions, e.g.
radio, by pressing the corresponding
button or wait until the telephone is ac-
tive.

One of the two messages “No telepho-
ne” or “Telephone not connected” ap-
pears.
