USING THE 150SX

MENU FUNCTIONS

on personal preference. You can select one of

11 sensitivity settings from -5 to +5. A setting of 0 (factory setting) has no effect on the auto-

matic sensitivity control. Increasing the

sensitivity (+1 through +5) enables the unit to display the information from progressively smaller sonar returns. By decreasing the sensitivity bias (-1 through -5), the unit effectively filters small sonar returns.

In murky or muddy water, it is often helpful to reduce the sensitivity. This prevents the display from being cluttered with sonar returns from debris or suspended particles. In very clear or very deep water, it may be helpful to increase the sensitivity since even the smallest sonar return may be of interest to the user.

To adjust Sensitivity, press MENU repeatedly until the Sensitivity heading is displayed. When the Sensitivity menu appears, use the UP ARROW to increase the sensitivity, or the DOWN ARROW to reduce sensitivity. To sequence through the available settings, press and hold either ARROW button. Release the button at the setting you want to change.

After an adjustment is made, the menu disappears and the new sensitivity setting is in affect.

Depth Range. The Depth Range function controls the vertical distance displayed on the graphic area of the display. There are nine depth ranges available. The top of the range is always 0, or the surface of the water. Ranges of 0–15', 0–30', 0–60', 0–120', 0–180', 0–240', 0–360', 0–480', and 0–600' are available. In the metric

version, ranges of 0–5, 0–10, 0–20, 0–40,

0–60, 0–80, 0–110, 0–150, and 0–185 meters are available.The range that positions the bottom depiction closest to the bottom of the screen, will best utilize the available display resolution.

The 150SX automatically adjusts the depth range depending on the depth of the water. The unit tries to maintain the bottom depiction about ²⁄₃
