3.Press → to the first number, then press ↑ to change the number to 1.

4.Press → to the second number, them press ↑ to change the num- ber to 5 and press EXIT. The depth indicators now accurately show the water depth from surface to bottom.

Sensitivity & Auto Sensitivity

The sensitivity controls the ability of the unit to pick up echoes. Sensi- tivity can be adjusted, because water conditions vary greatly. A low sensitivity level — from zero to 50 percent — excludes much of the bot- tom information, fish signals and other target information.

High sensitivity levels let you see this detail, but it can also clutter the screen with many undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Colorline and some surface clutter.

Automatic Sensitivity

The default sensitivity mode is automatic. The unit bases the sensitiv- ity level on water depth and conditions. When the unit is in the auto- matic mode, sensitivity is automatically adjusted to keep a solid bottom signal displayed, plus a little more power. This gives it the capability to show fish and other detail.

Situations occur when an increase or decrease in sensitivity is needed. An increase in sensitivity is necessary when you want to see more de- tail. A decrease in sensitivity will clear up the screen when it becomes cluttered by tiny air bubbles caused by boat wakes or wave action.

The control bar used to adjust sensitivity up or down is the same whether the unit is in the automatic or manual mode. In automatic you can adjust sensitivity up to 100 percent, but the unit will limit your minimum setting. In auto, the unit will continue to make small ad- justments, allowing for the setting you selected.

In manual mode, you have complete control over sensitivity with the ability to set it anywhere from zero to 100 percent. Once you select a level in manual, the unit will continue to use that exact sensitivity set- ting until you change it or revert to auto mode.

To adjust sensitivity in auto mode:

1.Press MENUENT.

2.The Sensitivity Control Bar appears. Press ↓ to decrease sensitivity. Press ↑ to increase sensitivity. When it is set at the desired level, press

EXIT.
