1 The BEARING CARD is shown in white colour outermost

in the echo ring, and is relative to the ship’s bow. The

bearing card has a stroke for each 10°.

2 The COMPASS CARD is also shown outermost in the echo

ring, but in a yellow colour. Because this compass card is a

replica of the coursereadoutinthe lower right-hand corner,

and always depends on a correct adjustment and

interfacing to the gyro, this readout should never be used

for navigation.

3 The DISTANCE RINGS are shown with white dashed

rings in the horizontal pictures, and white dashed lines in

the vertical pictures. The distance rings and lines divide the

total range into four, to make it easier to calculate the

distance or depth to a target.

4 The CURSOR RING is a yellow dashed ring with a radius

like the distance to the yellow cursor cross. The size of the

ring will change when operating the cursor joystick, and it

can then be used for distance measurements.

5 The CURSOR BEARING is a yellow line from the ship

symbolthroughthe yellowcursor cross, andcanbe used for

bearing measurements.

6 The BOW MARKER is a white dashed line which is an

extension of the bow or the sailing direction. This marker is

useful as a sight for the ship’s manoeuvring.

7 The COURSE LINE indicates the ship’s and targets’

movement as a path after the symbol. The length of the

course line depends on the manoeuvring of the symbol. To

erase the course line, it has to be ”switched OFF” in this

menu.

8 The MINUTE MARKERS are shown as small circles on the

ship’s and targets’ course line. In the audio and echo

sounder modes, they are shown as small lines at the top of

the recordings.

9 The WIND MARKER is indicated in the outermost area of

the echo presentation as an arrow. This arrow can be

manually adjusted in the WIND MARKER menu to show

the wind or current direction.

10 The VERTICAL RING shows the selected range of the

vertical slice as a white circle in the horizontal picture. This

will then be an indication of which distance a target should

be presented in the vertical slice.
