PRINCIPLE OF OPERATION This Color Video Sounder determines the distance between its transducer and underwater objects such as fish, lake bottom or seabed and displays the results on a 5.6-inch color screen. It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per second. When a sound wave strikes an underwater object such as fish or sea bottom, part of the sound wave is reflected back toward the source.

2.BASIC OPERATION 2.1 Turning the Power On/Off Turn the [MODE] switch clockwise to turn the power on. The unit starts with the settings used before it was turned off last time. To turn the power off, turn the switch fully counterclockwise. 2.2 Adjusting Brilliance Use the [BRILL] key to adjust the brilliance. The selected brilliance level is shown on the display as below. There are six levels of brilliance including off. BRILL:0 2.3 Display Mode Selection, Description 2.3.1 Display mode selec

2.3.2 Display mode description 200K, 50K (high frequency, low frequency) mode The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse the wider the detection area. Therefore, the 50KHz frequency is useful for general detection and judging bottom conditions, while the 200KHz frequency is useful for detailed observation of fish schools. DUAL frequency mode This mode provides the 50KHz picture on the left-half of the screen and the 200KHz on the right

ZOOM mode (high or low frequency) Three types of zoom displays are available: marker zoom, bottom-lock expansion, bottom zoom. The zoom mode to be used can be selected on the main menu with ZOOM MODE. This mode expands selected area of the normal picture to Normal full vertical size of the screen on the left-half window. You display may specify the portion to expand with the VRM (Variable Variable range Range Marker), which you can shift with [ ]or [ ]. The marker(green) area between the VRM and

2.4 Adjusting Gain The [GAIN] control adjusts the sensitivity of the receiver. Adjust it so that a slight amount of noise remains on the screen. Generally, use a higher gain setting for greater depths and a lower setting for shallower waters. Note: The [GAIN] control is inoperative when the automatic mode is active. Gain too high Gain proper Gain too low 2.5 Automatic Operation Automatic operation is useful when you are preoccupied with other tasks and do not have time to adjust the disp

2.6 Selecting Picture Advance Speed The picture advance speed determines how quickly the vertical scan lines run across the screen. When selecting a picture advance speed, keep in mind that a fast advance speed will expand the size of the fish school horizontally on the screen and a slow advance speed will contract it. 1.Press the [BRILL] and [AUTO] keys together. The display should look something like the one below. The fraction shown on the display denotes number of scan lines produced per
