Zoom Level

(Sonar Zoom View Only)

Zoom Level sets the magnification level for the Sonar Zoom View, and is only
available on the X-Press™ Menu when the Sonar Zoom View is active. 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.
