* NOTE Damage to the CI+ module and
Smart Card
The CI+ module is designed for use in the
home. The CI+ module can overheat and be
damaged by continuous exposure to high out-
side temperatures.
Make sure that the CI+ module is not
#
subject to high temperatures for exten-
ded periods of time.
If the CI+ module is damaged, no
encrypted channels can be received.

The CI+ module is not available in all coun-
tries.
A CI+ module (Common Interface Module), which
is not included in the scope of delivery, is used to
decrypt HD programmes according to the CI+
standard.
In some countries, an additional smart card is
required, which is inserted into the CI+ module
(see the manufacturer's operating manual).
The CI+ module is connected in the CI+ box in the
glove compartment.
To insert the smart card in the CI+ module: if
#
required (country-dependent), insert the
smart card into the CI+ module slot.
%
The CI+ box is designed for operation at tem-
peratures between 0 °C and 65 °C. At oper-
ating temperatures that are higher or too low
a message appears in the multimedia system
and the CI+ module is switched off automati-
cally. If the CI+ module is switched off, no
encrypted channels can be received.
