Telit Mobile Terminals S.p.A. SAT551 Manuel D’Utilisation

11 

Cradle 
 
The cradle connects your Telit Sat 550 telephone to the car kit allowing 
you to use it with the micro telephone or in hands-free mode. When 
connected to the amplifier using a coaxial wire, the cradle amplifies the 

audio output, removes the echo, charges the Sat 550’s battery and keeps 
it charged, and connects the telephone to the vehicle IO devices. 
 
Amplifier 
 

The amplifier (ODU) connects the external Globalstar antenna to the car 
kit. This must be housed in the passenger compartment or the boot of the 
vehicle, so as not to interfere with the normal use of the vehicle. It must 
also be so positioned that it is easily connected to the cradle (using the 5 m 
coaxial wire provided) and the magnetic external antenna (using the 2 m 

coaxial wire provided). 
 
Micro telephone 
 
The micro telephone (included in the pack) allows you greater privacy 

during a conversation than when using the hands-free mode. The use of 
the micro telephone automatically disables the hands-free feature.  
 
Note: It is possible to change from a private conversation to the 
hands-free mode, by simply replacing the micro telephone in its 
cradle. To end a call, the 

e key must be pressed on the Sat 550. 

 
Loudspeaker and Microphone 
 
The loudspeaker is fitted with a 2.8 m wire for connecting it to the cradle 
via the 3.5 mm stereo jack. When installing, position the loudspeaker at 
least 1 m from the microphone and 

not facing it.
