Note:  Eliminating the interference on frequencies used for marine communications and navigation due to 
operation of the radar. 
All cables of the radar are to be run away from the cables of radio equipment. 
(Ex. Radiotelephone.  Communications receiver and direction finder, etc. ) 
Especially inter-wiring cables between scanner unit and display unit of the radar should not be run 
parallel with the cables of radio equipment.
