The CONNECT system is able to de-
tect both internal faults and faults due
to overheating.INTERNAL FAULTS
If the system detects an internal fault
on a certain module (audio, telephone,
etc…), the system will “freeze” the
last available screen and it will start di-
agnostics.
For a set period of time the system
monitors the involved module for
troubleshooting. If time-out expires
with no result, the system will adopt
the best repair action (e.g.: resetting
involved module hardware).OVERTEMPERATURE
FAULTS
If the temperature of a CONNECT
system hardware module (audio, tele-
phone, CD player, etc..) exceeds the
max. limit, the involved module will
detect overtemperature and the dis-
play will show a dedicated warning
message.
The involved module will automati-
cally be limited or disabled. In extreme
cases the system is turned off auto-
matically until regular operating tem-
perature is restored. The display will
show the screen in fig. 176.

ing message.

In case of excessive overtempera-
ture, a warning message will inform
the user that the auto-off procedure
has been activated. The system can be

Soft Mute function
When the MUTE function (audio sys-
tem) or NAV MUTE (navigator) is
turned on or off, the volume lowers
or highers gradually (Soft Mute func-
tion). The Soft Mute function is also
turned on pressing one of the six pre-
set keys 1 ÷ 6 fig. 1, key 11-fig. 1or
key 12-fig. 1for tuning radio stations. To turn off the NAV MUTE function
press the “NAV” key 20-fig. 1at
length: the volume will gradually in-
crease (Soft Mute function) returning
to the value set previously.
With the NAV MUTE function on, all
the other navigator functions are us-
able and if traffic information is re-
ceived with the TA function on or an
emergency alarm is received the mes-
sage ignores the MUTE function.PROTECTION AGAINST
OVERHEATING
The components of the telematic
system are protected against over-
heating. The device stops it from
working when the temperature of the
module exceeds the established limit.
In this case the function activated by
the module that has reached the tem-
perature limit is switched off and the
display shows a warning message for
the user.
To resume the interrupted function,
the user should wait for the temper-
ature of the module to fall below the
limit; this condition will be indicated
by the message going off from the dis-
play followed by the reactivation of the
function.
Conversely, to exit the screen with
the message immediately and activate
a different function, press “ESC” 23-
