Auto Tilt
This is an "on/off" function. When Auto Tilt mode is activated the beam will automatically change its tilt angle for each transmission ("ping"). The centre of the tilt sector is defined by the chosen tilt angle just before the Auto Tilt mode is started. The chosen tilt sector is shown on the tilt indicator in the Horizontal view using a shaded background. The sector and step settings are made using the Tilt function on the Main menu.
Off Centre
This is the same function as Set New Ship Centre on the shortcut menu. Place the cursor anywhere in the view and press the button. The function moves the vessel symbol to the selected position.
Zoom
Place the cursor anywhere in the view, right-click and select Zoom. Only one zoom level is provided. Select Zoom one more time to restore the original view.
Menu Off
This is an "on/off" function. Unless you need to make frequent changes to the operating parameters, you may want to hide the menu from the display presentation. This gives you more space for echo information.
Audio
Select Audio to turn the audio output on or off.
Own Ship
This is the same function as Place Own Ship Marker on the shortcut menu. Select this function to add a square symbol to the vessel’s current position in the echo presentation. The own ship marker is now regarded as an object. All information about the object is shown in the Objects menu listed as "OSM". Use Delete Own Ship Marker on the shortcut menu to delete the marker from the current view.
Auto Bearing
This is an "on/off" function. Set this function to On to start the automatic search function. In the Auto Bearing mode the ST90 system will automatically search within defined sector limits. The sector is identified in the view using two angular symbols. The sector and step settings are made using the Bearing function on the Main menu.
Screen Recording
This is an "on/off" function. The Screen Recording function allows you to record and save the echo presentation as a video file. Each screen recording you make is saved in .mp4 format on the Processor Unit hard disk. The file name reflects the current date and time.
Select Screen Recording to start and stop the recording from the Operating Panel.
Use the Screen Recording page to define where the video files are saved. This page is located in the Output dialog box.
Delete Oldest Marker
The ST90 offers several different marker types. You can add as many markers as you like. The most common markers can be added using dedicated buttons on the Operating Panel. Other markers are added using the shortcut menu in each view. Each marker is identified with its geographical location.
Select Delete Oldest Marker to use the Operating Panel to remove the oldest marker from the sonar view.
