Description
Only brief descriptions are provided. For detailed information about each function and dialog box, refer to the Reference manual or the context sensitive on-line help.
Tip
If you do not need to use the menu system, you can hide it. This allows more space for the echo presentation.

Use Menu on the top bar to hide or show the menu.
When the menu system is hidden, it appears temporarily on the left or right hand side of the screen if you move the cursor to that position.
The choices in the this menu depends on which view in the display presentation that is currently "active". The menu may therefore change from one view to another. The screen capture may not show you all the menu choices.
•  Visual Objects
Visual Objects is an "on/off" button used to open the Visual Objects menu. The Visual Objects menu controls which graphical elements that are shown in the different views. These graphic elements include markers, vectors and targets that are tracked. The majority of the functions are "on/off" buttons to enable or disable these graphic elements in the various views.
•  Cosmetics
Use the functions on the Cosmetics menu to turn "cosmetic" elements in the sonar presentation on or off. The majority of the functions are on/off buttons to enable or disable "cosmetic" elements in the sonar views. This function is not available in all the views.
•  Motion
In selected views you can control how the vessel symbol shall "behave" in the presentation. The way the vessel moves in the presentation can be chosen either true or relative.
•  Transparency
When you open an information pane, you will see that it is transparent. This transparency allows you to see the echo data behind the pane, but it may also reduce the visibility of the information in it. The transparency can be adjusted.
•  View Range
Use View Range to expand the range shown in the relevant views to any percentage of the original Range setting. This function can be used if you wish to move your ship symbol to the bottom of the view. You can then expand the range without adding zoom.
•  Display Gain
Use the Display Gain function to increase or decrease the strength of the echo presentation.
•  Panel Backlight
The buttons on the Operating Panel have built-in backlight to improve visibility on a dark bridge. Use Panel Backlight to control the intensity of the lights.
•  Colour Threshold
The Colour Threshold function allows you to reduce or increase the number of colours. This will provide a filtering effect that removes the weakest echoes.
•  Screen Brightness
The intensity of the light given off by the display presentation can be adjusted. You can use this function to increase or decrease the light from the screen to match the ambient light.
•  Display Options
The top bar gives you fast access to key functionality and navigational information. It provides buttons to hide or show the menu, to monitor data recording, to open the Messages dialog box, and to open the context sensitive on-line help. Which navigation elements to see on the top bar is selected in the Display Options dialog box. It controls the location of the menu. You can also select which tooltips to appear when you move the cursor over the echo information.
–  General
The General page in the Display Options dialog box controls the location of the menu. You can select which navigational information to be shown on the top bar. You can also choose to see Coordinated Universal Time (UTC) at the bottom of the presentation.
–  Tooltip
When you move the cursor over the echograms in the display presentation, small "tooltips" are shown to provide additional information. The Tooltip page controls which tooltips that are shown.
–  Track Line
In order to maintain a visual presentation of your vessel’s previous movements, you can draw these with a line. This line is drawn after the vessel symbol in the sonar views, and visualizes your past movements. We refer to this line as the Track Line. The track line provides a line representing the previous positions of your own ship. Use the settings on the Track Line page to define the length (in minutes) for the track line.
–  Vertical View Orientation
The Vertical View Orientation page allows you to decide whether the vertical views should be presented from right to left, or from left to right.
–  Off Centre
When the vessel symbol is moved away from the centre of the view, more space is made available for the echo presentations. If you keep the same range setting, this added space causes a "zoom" effect. The distance from the vessel to the outer edge of the search area is the same, but it is "stretched" out. You may not want this to happen.
–  Current Flow
A current sensor can be connected to the SU90 system. This can for example be an acoustic Doppler current profiler (ADCP). The information from this sensor is presented in the applicable views. Use the Current Flow page to define key settings for the presentation of the sensor data.
•  Colour Setup
The Colour Setup dialog box controls the presentation colours used by the SU90 system. This includes the palette ("skin"), the number of colours in use, and the colour scale when no TVG has been selected for the presentation
•  Docking Views
Each operating mode is presented with a set of views. These are placed at different positions with different sizes. With the Docking Views function you can move and re-size the views in the display presentation.
