Upper Range

(Advanced: Sonar, Split Sonar, Big Digits and Circular Flasher Views only)

Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split

Sonar, Big Digits and Circular Flasher views. The Upper Range menu choice is available

when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be

accessed from the Sonar, Split Sonar, Big Digits and Circular Flasher views. Upper Range

is often used with Lower Range.

NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower

Range regardless of the manual settings entered.

To adjust the Upper Range:

1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar

X-Press

Menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the

Upper Range setting. (0 to 590 feet or 0 to 237 meters [International Models

only], Default = 0)

For example, if you are only interested in the area between 20 and 50 feet deep,

you should set the Upper Depth Range to 20 and the Lower Depth Range to 50.

The Sonar View will then show the 30 foot area between 20 and 50, and will not

show the surface or the bottom (assuming the bottom is deeper than 50 feet), and

will show greater detail for that area between 20 and 50 feet.
