Before switching to operation mode, check all connections between PA and TCVR. 

 

  

We are now back in the 

Main display

, bar 

graphs defined, antennas preprogrammed, 
CAT  was  set.  We  are  ready  to  go  to  the 
operation mode. 

Press the black 

STBY/OPER

 button on the 

front panel. 

 

 

 

 

 

We are now in OPERATE mode.  

Note the light indicator on the touch  
Screen has changed to
