CHART SPEED

Chart Speed determines the speed at which the sonar information moves across the display, and consequently the amount of detail shown. A faster speed shows more information in the Sonar Views and is preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, but the bottom and fish details become compressed and may be difficult to interpret. Regardless of the Chart Speed setting, the RTS® Window will update at the maximum rate possible for the depth conditions. Adjust Chart Speed to your personal preference.

To adjust the Chart Speed:

1.Highlight Chart Speed on the Sonar X-Press™ Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Chart Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest, Default = 4)

ZOOM LEVEL

(Sonar Zoom View, 931c DF and 931c models only)

Zoom Level sets the magnification level for the Sonar Zoom View, and is only available on the Sonar X-Press™ Menu when the Sonar Zoom View is active on 931c DF and 931c models. Use Zoom to increase the display resolution to separate sonar returns that are very close together.

To adjust the Zoom Level:

1.Highlight Zoom Level on the Sonar X-Press™ Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Level setting for the Sonar Zoom View. (2x, 4x, 6x, 8x, Default = 2x)

NOTE: The Zoom Preview Box tracks the bottom and cannot be moved by the user.

BOTTOM LOCK

(Sonar Zoom View only)

Bottom Lock changes the mode of the Zoomed view in the Sonar Zoom View.

To turn on Bottom Lock:

1.In the Sonar Zoom View, highlight Bottom Lock on the Sonar X-Press™Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom Lock setting to on. (Off, On, Default = Off).

3.Once you turn on Bottom Lock the Bottom Range X-Press menu choice will be displayed. Bottom Range allows you to control the height above the bottom that is shown in the Zoomed view. (10 - 60 feet, 2-10 fathoms, or 3-20 meters [International Models Only])

SONAR COLORS

Sonar Colors allows you to select which color palette you would like to use for the display.

To change the Sonar Colors:

1.Highlight Sonar Colors on the Sonar X-Press™menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the color palette. (Standard, Gray, Inverse, Green, Default = Standard)
