8.3.1  PULSE REPETITION FREQUENCY FINE TUNING       
(PRF FINE TUNING) 
 
If radar’s interference patterns are concentrically displayed, increment or decrement the set value by 3 to 4 in 
order to heighten the effect of interference rejection. 
PRF Fine Tuning:
 
Fine-tune the transmitting repetition frequency of the transmitter in the range 90% to 100%. 
This setting cannot be performed simultaneously with the setting of “STAGGER TRIGGER”. 
 
8.3.2  STAGGER TRIGGER 
 
Turn on/off the interference reduction function controlled by the transmission repetition frequency control of 
the transmitter. 
This function is effective when radar interference does not go away. 
This setting cannot be performed simultaneously with the setting of “PRF FINE TUNING”.
