Select the range option and then the auto option in the menu.
Custom range
This option allows you to manually set both upper and lower range
limits.
Set a custom range by selecting the range menu option and then
the custom option.
Ú Note:
Setting a custom range puts the system in manual range
mode.
Frequency
The unit supports several transducer frequencies. Available
frequencies depend on the transducer model that is configured for
use.
You can view two frequencies at the same time by selecting dual
Sonar panels from the Home page.
Sensitivity
Increasing sensitivity shows more detail on the screen. Decreasing
sensitivity displays less. Too much detail clutters the screen.
Conversely, desired targets may not be displayed if sensitivity is set
too low.
Ú Note:
Auto Sensitivity is the preferred mode for most
conditions.
Auto sensitivity
Auto sensitivity automatically adjusts the sonar return to the
optimal levels. Auto sensitivity can be adjusted (+/-) to your
preference while still maintaining the auto sensitivity functionality.
Colorline
Allows the user to adjust the colors of the display to help
differentiate softer targets from harder ones. Adjusting the Colorline
can help separate fish and important structures on or near the
bottom from the actual bottom.
