HI guys 
  
I have recently become the 'fix it' guy for a small string of shops. 
  
They have a brand new AVC791B that was installed by some unknown person  
It appears he changed the default PIN.... 
  
Does anyone know how to reset it to factory? I need to reset the PIN, its not the standard 0000. 
  
Also, I tried the R288 jumper trick, and it doesn't seem to reset. 
  
  
Any tips? 
  
Regards 
matthew
