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 heightand the radar beam width) the cables supplied with the equipment have been installed correctly. In particular, checkfor 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 inplace, so that the internal shielding is effective each piece of radio equipment is grounded to the closest ground location, and that otherdevices 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 thedirection finder cabling. The radar cabling must always be separate.16.5 Make sure the power is present and correctly wiredCheck the in-line fuse.Re-verify that the correct system voltage is being used for the radar processor box model and that thepower is properly wired. If the radar processor has incorrect power, the system may not initializeproperly or the radar processor may be damaged.16.6 Confirm the equipment installed1. 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 array4. Make sure the voltage input and radar processor are correct for the system being installed, asfollows: 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 NS004784.16.7 Are Range Rings displayed?Yes, range rings are displayed.1. Confirm that the installation set up had been performed.2. Verify that the array is turning. If it's a dome, with the power off, remove the dome cover(weather permitting). Apply power to the system.
