SONAR OPERATION
PAGES
Turn the unit on by pressing the PWR/LIGHT key. If the sonar screen is not showing, press the PAGES key. A menu similar to the one at right appears. Press the left or right arrow key to highlight the Sonar label. This gives you four selections: Full Sonar Chart, Split Zoom Sonar Chart, Split (Dual) Frequency Sonar Chart, or Digital Data only. Once the de-
sired menu is selected, press the EXIT key to erase the menus.
Full Sonar Chart
This is the default mode used when the unit is turned on for the first time or when it’s reset to the factory defaults. The bottom sig- nal scrolls across the screen from right to left. Depth scales on the right side of the screen aid in de- termining the depth of targets. The line at the top of the screen represents the surface.The bot- tom depth and surface tempera-
ture (if equipped with a temperature sensor) show at the top left corner of the screen. The FasTrak™ display shows just to the right of the scale. This changes all echoes into short horizontal bars, replicating a flasher sonar. The zoom bar on the far right shows the area that’s zoomed when the zoom is in use. (See the Zoom section for more information.) The frequency of the transducer in use shows at the bottom of the screen.
