Switching on the telephone and the car kit 
 

The telephone and the car kit switch on automatically when the vehicle‘s 

ignition is switched on (if the white wire has been connected). For information 

on operating the Sat 550, consult its instruction manual. 

If the Sat 550 is correctly placed in the cradle, the display will show the 

symbol

Note: Do not switch the telephone on when  its use is forbidden or 
when the unit could cause interference on dangerous situations.  
 
 

 

 

 
 
 

 

 

 

 
 

 

 
Hands-free mode 
 
Once the Sat 550 has been placed in the cradle and switched on, calls can 

be made and received in hands-free mode immediately. 

For best  results in communication, we suggest you speak towards the 

microphone. The caller’s voice will be heard over the external speaker.  

 
Note: Always pay maximum attention to driving while having a 
conversation.  
Before making a call the vehicle must be stopped in a stopping zone.
