Bottom Lock
(Sonar Zoom view only)
Bottom Lock changes the mode of the Zoomed view in the Sonar Zoom View. Bottom
Lock continuously graphs the bottom at a constant point on the display regardless of
changes in depth. This "flattens" out the bottom contour, but is effective at showing fish
on or near the bottom.
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)
Cancel Navigation
(only when Navigating)
Cancel Navigation discards the current route and exits Navigation Mode. This menu
choice will only appear when you are currently navigating a route. This will not delete a
previously-saved route.
To Cancel Navigation:
1. Highlight Cancel Navigation on the Sonar X-PressTM menu.
2. Use the RIGHT 4-WAY Cursor Control key to initiate canceling navigation.
3. The Confirm dialog box will appear. To cancel navigation, press the RIGHT
Cursor key once more. To avoid canceling navigation, press the LEFT Cursor key.
4. The Save Current Route dialog box will appear. Use the RIGHT 4-WAY Cursor key
to save the route or the LEFT 4-WAY Cursor key to decline saving the route.
