Check the motor and replace any faulty component. (See the Service Manual for information 

on replacing the motor) 

Check the wiring of the interconnection cable between the scanner and the radar processor. 

Checking these connections is especially important if the installer removed the connectors for 

easy routing when installing the scanner cable.

How to reduce noise and interference 

If other electronic equipment on the vessel is being affected by noise interference from the radar, 

check that the radar is actually the source of the problem by switching it off, running the other 

electronic equipment for a while to see if the noise interference has disappeared, and then 
switching the radar on again.  

If the radar is causing the noise interference, check that: 

 

the affected piece of equipment and/or the antenna is not located within the radar beam.  (See 
the section "Install the radar" for information about the optimum installation height and the 

radar beam width) 

 

the cables supplied with the equipment have been installed correctly.  In particular, check for 

loose connections and loose or missing shield meshwork at the cable ends 

 

the covers of the scanner and radar processor box are securely screwed and/or fastened in 
place, so that the internal shielding is effective 

 

each piece of radio equipment is grounded to the closest ground location, and that other 
devices are grounded to the closest ground location on the hull 

 

the radar cabling has not been bundled with the VHF radio cabling and/or with the direction 

finder cabling. The radar cabling must always be separate. 

 

12.5

 

Make sure the power is present and correctly wired 

Check the in-line fuse. 

Re-verify that the correct system voltage is being used for the radar processor box model and 
that the power is properly wired.  If the radar processor has incorrect power, the system may not 

initialize properly or the radar processor may be damaged. 

 

12.6

 

Confirm the equipment installed 

1.  Confirm the type of navigator used with the radar (6000i, etc). 

 

Serial number:___________________ 

 

Software version:_________________ 

2.  Confirm that the NMEA Port 2 interface option is set to RADAR. 

3.  Confirm the type of radar installed: 

 

2 kW dome 

 

4 kW dome 

 

6 kW open array 

 

10 kW open array 

 

25 kW open array 

4.  Make sure the voltage input and radar processor are correct for the system being installed, as 

follows: 

 

2 kW - 12 V DC - Radar Processor NS004780 

 

4 kW - 12 V DC or 24 V DC - Radar Processor NS004781 

 

6 kW - 12 V DC or 24 V DC - Radar Processor NS004782 

 

10 kW - 24 V DC - Radar Processor NS004783 

 

25 kW - 24 V DC - Radar Processor NS004784.
