to enable all telephone functions
(page 78).

function steering wheel.In the following situations, it is not possible
or not yet possible to use the telephone:

is not or not yet registered in the net-
work.

an existing network. If the network is
available, the telephone will be ready
for use.

if the network is no longer available
due to weak signals

vated. Please wait.” appears.
