When the X-70A 3D is turned on, the Fish I.D. feature is automatically turned on, also. To turn the

Fish I.D. feature off, press the MENU key, then press the key adjacent to the “Fish ID” label. This moves the check mark from the “ON” to the “OFF” box. The unit returns to the sonar display with Fish ID off. To turn the Fish I.D. feature on again, repeat the above steps. The menu immediately disap- pears and the sonar screen returns. In the 2D mode, ech- oes will continue to scroll

across the screen, however, the surface clutter at the top will no longer be displayed. Any targets the microcomputer determines are fish will be dis- played as fish symbols.

Remember, the Fish I.D. feature can’t be used when the X-70A 3D is in the manual mode.
