7.2 

Synchronization 

When AM systems or AM deactivators are installed in relative close vicinity of each other, 
it  is  of  extreme  high  importance  that  the  transmission  bursts  of  all  transmitters 
(transceivers) occur at the same moment. To be able to view and change the position of 
these transmission bursts, the Synchronization screen is available. 

 

 

When the Synchronization screen is open, the transmission burst of this 
deactivator is disabled. As a result of this, the deactivator will not detect 
any  labels!  Make  sure  to  leave  this  screen  to  enable  detection  and 
deactivation of labels again. 

 

When the transmission bursts are not synchronized properly, unwanted deactivations and 
reduced sensitivity will be the result. The Synchronization screen will show exactly if and 
where other system transmission bursts are detected. 

 

Figure 10: Synchronization 

 

We now have two ways of synchronizing the systems; manually or automatically. 

 

 

It  is  advised  to  tilt  the  deactivator  in  a  vertical  position  when 
synchronizing  the  unit,  as  it  will  detect  other  AM  systems  and 
deactivators  better,  making  it  easier  to  properly  synchronize  all  AM 
devices.
