2D VIEW OPTIONS

The 2D view has several ad- justments that (with some ex- ceptions noted below) affect the 2D view screen only. To use these options, first press the MENU key, then press the key next to the “2D VIEW OP- TIONS” label. A menu similar to the one at right appears.

DIGITAL BOX OPTIONS

The X-70A 3D can display the depth, speed, surface water temperature, and distance log on all sonar screens, including the 2D, 3D, Bottom Depth View, and FasTrak. (Speed, temperature, and log displays require an op- tional speed/temperature sensor.) When the X-70A 3D is first turned on, only the depth is displayed if the sensor is not connected. You can turn each digital display on as desired or turn all of them off, as desired.

To select the digital displays menu, first press the MENU key. Next, press the key adjacent to the “2D View Options” label. Finally, press the key next to the “Digital Box Options” menu. The screen shown below appears.

Now press the key adjacent to the desired display. For example, to turn the temperature display on, press the key adjacent to the “TEMPERA- TURE” label. Once you do this, the digital display in the corner of the screen will show the temperature in addition to the depth. You can turn each display on or off, individu-

ally.

If you wish to turn all of the digital displays off, simply press the key next to the “DIGITAL BOX” label. Press the CLEAR key to exit from this menu.
