16. RADAR OVERLAY
5. [INT Reject] reduces radar interference. Radar interference can occur when your vessel is in the area of another radar that operates in the same frequency band (3 GHz) as own radar. The interference is seen on the screen as a number of bright spikes either in irregular pattern or as dotted lines that extend from the center of the edge of the picture. When this type of interference appears on the screen, use the interference rejector.
Four settings are available, [1], [2], [3] and [OFF]. The higher the setting the greater the degree of interference rejection. Turn the rejector off when no interference is present, so as not to miss small targets.
6. [Initiative Range], when checked, sends the current ECDIS range to the RCB. For example, the current ECDIS range is 4 NM. Then, “4 NM” is sent to the RCB and the RCB sends echo data within that range to the ECDIS. If multiple ECDIS units are in the system, only one ECDIS can have [Initiative Range] checked, so all EC-
DIS displays are synched. If unchecked, the radar sends echo data corresponding to the previously set ECDIS range.
7. Click the [RCB Detail Settings] button to show the [RCB Detail Settings] dialog box. Set each item as shown on the next page. The dialog box has two divisions,
[Common] and [Individual]. The [Common] settings apply to all the radars connected to the ECDIS via the Radar Connection Box. The [Individual] settings apply to the radar currently feeding echo data to the ECDIS via the Radar Connection
Box.
Note: For FURUNO radars, it is recommended to use the settings set on the radar in order to match the radar overlay picture with the radar picture.
