Customizing The Image - Simrad NSO evo3S MPU Operator's Manual

MAP Genesis. You can sign in and transfer files at a later time when the unit is connected
to the internet.

Customizing the image

Use the menu to customize the image. When the cursor is active, some options in the menu
are replaced with cursor mode features. Select the clear cursor option to return to the normal
menu.
Range
The range setting determines which water depth that is visible on the screen.
Ú Note:
Setting a deep range in shallow water may cause the system to lose track of the
depth.
Frequency
The unit supports several transducer frequencies. Available frequencies depend on the
transducer model that is configured for use.
• A low frequency, for example 50 kHz, will go deep. It generates a wide cone but is more
sensitive to noise. It is good for bottom discrimination and wide area search.
• A high frequency, for example 200 kHz, offers higher discrimination and is less sensitive to
noise. It is good for separating targets and for higher speed vessels.
Gain
The gain controls the sensitivity. The more you increase the gain, the more details are shown
on the image. However, a higher gain setting may introduce more background clutter. If the
gain is set too low, weak echoes might not be displayed.
A manual and an automatic gain mode are available. By default, the gain is set to Auto.
Color
Strong and weak echo signals have different colors to indicate the different signal strengths.
The colors used depend on which palette you select.
The more you increase the color setting, the more echoes are displayed in the color at the
strong return end of the scale.
Source
Ú Note:
Available only if multiple sources with the same capability are available.
Used to specify the source for the image in the active panel.
You can display different sources simultaneously, using a multi-panel page configuration.
Menu options for each panel are independent.
Ú Note:
Using transducers at the same frequency can cause interference.
For source setup information, refer to the NSO evo3S MPU Installation Manual.
Measuring distance
The cursor can be used to measure the distance between the positions of two observations
on the image.
1.
Position the cursor on the point from where you want to measure the distance
2.
Select the measure menu option
Ú Note:
The measure option is not available unless the cursor is placed on the image.
3.
Position the cursor on the second measuring point
