Main menu
The Main menu is located at the top of the menu structure. It offers the most common functions for efficient use of the SU90 system. Unless you hide the entire menu system, the Main menu is visible at all times, even if you close the secondary menus.

How to open
By default, the Main menu is open. It is placed on the right side of the SU90 presentation.
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.
Below the Main menu you find the icons for opening (and closing) the secondary menus. Select an icon to open the relevant menu, and reselect the icon to close the menu.
•  User Settings
The User Settings dialog box allows you to save the current user settings (your current selection of operational parameters), and to retrieve factory or previously saved user settings.
•  Range
The Range function allows you to specify the maximum distance from the transducer to the outer edge of the sonar beam. The range value shown and selected is by default only applied to the currently selected view.
•  Gain
The purpose of the Gain function is to adjust the echo level in the SU90 presentations. By adjusting the gain you can control how much amplification the SU90 system applies to the received echoes. The setting is by default only applied to currently selected echogram. It is identified with a thick border.
•  Tilt
The Tilt function allows you to control the vertical angle of the sonar beams.
•  Bearing
The Horizontal view in the SU90 presentation covers the entire xxx sector. For the other views you must define the horizontal direction of the beam. Use Bearing to adjust the horizontal angle referenced to the vessel heading.
