Homologation functionality 

 
For homologation use the Designkey samples are programmed with a special 
software which allows to set the RF transmission in following modes : 
 
1 ) Constant carrier high frequency 
2 ) Constant carrier low  frequency 
3 )   1 kBit Modulation 
4 ) 10 kBit Modulation 
 
The following diagram shows how to activate the different homologation modes.
