Using the Sonar Adjustment Menu

Use the Sonar adjustment menu to access the settings and features most

commonly used on the Sonar Page.

To select an adjustment option from the Sonar Page:

1. Press ADJ to open the Sonar adjustment menu.

2. Press up or down on the ROCKER to highlight the option you want to

change, and press ENTER.

3. Use the soft keys to make adjustments.

4. To exit any of the adjustment options, press the Back soft key, or press

QUIT.

To change a Sonar adjustment menu setting:

1. Select an adjustment menu option using the method described previously.

2. Press up or down on the ROCKER to change the setting, range, or

percentage (Off, 1-100%).

3. Press ENTER to accept the change, or QUIT to close the Sonar

adjustment menu.

The Sonar adjustment menu contains the following options:

•

Gain—controls the sensitivity of the sonar receiver. Auto (default) is the

recommended setting. It automatically sets the sonar sensitivity. You can

also set the gain manually. To see more detail on the screen, increase the

receiver sensitivity by selecting a higher gain. If there is too much detail or

if the screen is cluttered, lower the sensitivity (lower the gain) to increase

the clarity of the screen. If Frequency is set to Dual, you can set the Gain

separately for each frequency (50 kHz and 200 kHz).

•

Color Gain—controls what colors are applied to the objects on the screen.

Auto (default) is the recommended setting. It automatically sets the

colors, based on your Auto Color Gain setting. You can also set the Color

Gain manually. If Frequency is set to Dual, you can set the Color Gain

separately for each frequency (50 kHz and 200 kHz).

•

Whiteline—controls how the unit shows information about the bottom

type (hard or soft). With the Whiteline Off, the bottom return shows as red

and contains no information on bottom hardness. With Whiteline set at

Normal or 1-100%, the bottom return becomes white with a red line, in the

default color scheme, indicating where the water meets the bottom. To turn

the Whiteline Off, press the ROCKER down until the setting bar is all the

way at the bottom of the range and reads Off.
