A heater can melt the equipment's power cord, which can cause fire or electrical shock. Use the proper fuse. WARNING ELECTRICAL SHOCK HAZARD Do not open the equipment. [. . . ] Then, the Vertical 1 display appears, and the vertical bearing marker is displayed in the horizontal display, with "V" at the tip of the marker. If both vertical displays are activated, "1" or "2" is inscribed at the tip of a vertical bearing marker. 3. 4. 2 Auto train You may scan the vertical bearing mark in the sector of OFF, ±12°, ±24° and ±36°. Press and hold down the [AUTO TRAIN] key while pressing the [V1] or [V2] key to choose auto train sector desired. Selected sector appears in large characters for five seconds for your confirmation. The auto train starts. Auto train mark Auto train sector Vertical bearing mark 1 Figure 3-6 Auto train 2. VERTICAL MODE 3. 5 Display Range The [RANGE] control selects the detection range. The range selected is momentarily displayed in large characters at the center of the vertical 1 display. Range is always displayed at the lower left-hand corner of the vertical 1 display. Below are the default ranges (in meters). Range Setting Range 1 200 2 400 3 600 4 1000 5 1600 6 2000 7 3000 8 4000 1. Press the [H/V] key to show the gain and range indications of the vertical mode in yellow. Note: Ranges may be preset as desired on the PRESET, MEMORY CARD menu. For further details, see V-SCAN RANGE on page 8-5. 3. 6 Measuring the Range Operate the trackball to place the trackball mark on the vertical 1 (or vertical 2) display. The range to the location selected is shown at the top left corner.

VERTICAL MODE 3. 7 Eliminating Weak Echoes Echoes from targets such as bottom and fish return to the transducer in order of distance to them, and when we compare their intensities at the transducer face, those from nearer targets are generally stronger when their reflecting properties are nearly equal. The sonar operator will be quite inconvenienced if these echoes are directly displayed on the screen, since he can not judge the actual size of the target from the size of echoes displayed on the screen. It compensates for propagation loss of sound in water; amplification of echoes on short range is suppressed and gradually increased as range increases so that similar targets are displayed in the similar intensities irrespective of the ranges to them. The FSV-24 has three TVG functions, NEAR, MEDIUM and FAR, and they mainly compensate for propagation loss on short, middle and long ranges respectively, centered at the ranges as shown in Figure 2-9 on page 2-8. The TVG is also used to suppress unwanted echoes and noise which appear in a certain range area on the screen such as sea surface reflections and cruising noise.
