B&G Zeus2 Glass Helm CPU - Manual (Page 70)

Saving waypoints
You can save a waypoint at a selected location by positioning the cursor on the panel, then
selecting the new waypoint option in the menu.
Viewing sounder history
Whenever the cursor is shown on a sounder panel, the scroll bar is shown at the bottom of
the panel. The scroll bar shows the image you are currently viewing in relation to the total
echosounder image history stored.
If the scroll bar is on the far right side, it indicates that you are viewing the latest soundings. If
you position the cursor to the left side of the screen, the history bar will start scrolling
towards left, and the automatic scrolling as new soundings are received will be turned off.
You can view echosounder history by panning the sonar image.
To resume normal scrolling, select Clear cursor menu option.
Setting up the Echosounder image
The range
The range setting determines the water depth that is visible on the screen.
Auto range
If you select Auto, the system will automatically display the whole range from the water
surface to the bottom.
Preset range levels
You can select between several preset range levels.
Custom range
This option allows you to manually set both upper and lower range limits.
The echosounder panel can be setup as a single view, or with split view where the left and
the right side presents different images.
Echo frequency
The Zeus 2 Processor unit supports several transducer frequencies. Available frequencies
depend on sounder module and which transducer model is connected.
You can view two frequencies at the same time by setting up a dual echosounder.
Color and gain settings
Gain and Color control images are located in the left side of the echosounder panel. You
select between the control images by selecting the image or by pressing the rotary knob on
an ZC1. Active control will expand and display its name in full. You can then adjust the value
by using the slide bar or by turning the rotary knob on the ZC1.
You can also adjust the image settings from the echosounder menu.
Gain
The gain controls the sensitivity of the echosounder.
The more you increase the gain, the more details will be shown on the image. However, a
higher gain setting may introduce more background clutter on the image. Conversely, if the
gain is set too low weak echoes may not be displayed.
Auto gain
The Auto gain option will keep the sensitivity at a level that works well under most
conditions.
With the gain in auto mode, you can set a positive or negative offset that gets applied to the
auto gain. This is indicated as A-40 - A40.
