Noise Filter

(Advanced)

Noise Filter adjusts the sonar Noise Filter to limit interference on the display

from sources such as your boat engine, turbulence, or other sonar devices. The Noise

Filter menu choice is available when User Mode is set to Advanced (see Setup Menu

Tab: User Mode).

NOTE: The Off setting removes all filtering; Low, Medium and High settings add progressive

filtering of the sonar returns. In some deep water situations, the High setting may actually

hinder your unit’s ability to find the bottom.

To change the Noise Filter setting:

1. Make sure you are in Advanced User Mode, then highlight Noise Filter on the

Sonar main menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Noise Filter

setting. (Off, Low, Medium, High1, High2, High3, Default = Low)

Max Depth

(Advanced)

Max Depth adjusts the maximum depth of operation. The performance of your

Fishing System can be tuned to the maximum depth you will be fishing in by setting the

Max Depth. When a maximum depth is set, your Fishing System will not attempt to

acquire sonar data below that depth, thus increasing overall performance. When

Max Depth is set to Auto, the Fishing System will acquire bottom readings as needed

(within the capacity of the unit). If the bottom is deeper than the Max Depth setting, the

digital depth readout will flash, indicating that the Fishing System cannot locate the

bottom. The Max Depth menu choice is available when User Mode is set to Advanced

(see Setup Menu Tab: User Mode).

To change the Max Depth setting:

1. Make sure you are in Advanced User Mode, then highlight Max Depth on the

Sonar main menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Max Depth

setting. (AUTO, 10 to 600 feet, 3 to 240 meters [International Models only],

Default = AUTO)
