(D) The VRM (Variable Range Marker) consists of an

adjustable range ring with range readout. It can be used for any

type of distance marking relative to the vessel. To adjust the

marker, locate the cursor on the marker ring, press

Select and

move the cursor with the Select button depressed. When the

button is released, the variable range marker radius will be

moved to the new cursor position.

(E) The Compass Card is shown as short yellow lines for every

10th degree along the outermost circle of the sonar view. A

triangle symbol indicates each 45th degree. It has labels

indicating North, East, South and West. It is updated when the

heading of own ship has changed more than 1 degree, if the

display mode is Bow up.

(F) The Vertical Ring shows the selected range of the vertical

slice as a full circle in the horizontal presentation. This is an

indication of which distance a target should be presented in the

vertical view. The Vertical Ring will only be visible in those

modes that support a vertical slice. In other modes, the button

will give no response.
