A larger track window will enable the system to track a large target more easily, but the system will be more susceptible to background noise. Smaller targets may be ignored if there is a lot of noise in the area, as the system will track the strongest echo within the track window. · Wind direction: The wind marker is show in the outer area of the echo presentation as a white arrow. This arrow can be manually adjusted for indication of the wind or current direction, or automatically show the wind direction if a wind sensor is connected. It is only a read-out of the current wind speed providing that a wind sensor is connected. This menu is used to select the display modes to be activated by the four Mode buttons on the Sonar Operating Panel. The four upper display modes in this menu will always be the four modes provided by the four Mode buttons in the order they are sorted. · External sync: This function makes it possible to eliminate interference from other Simrad sonars on board your vessel. If the sonars are connected together, you can use these settings to synchronise their transmissions. · Scientific output: This is an optional functionality designed to be used when the sonar is used for scientific purposes. When enabled, the sonar will provide special information on an ethernet port. · Fish alarm: This function makes it possible to set up the sonar to warn you when a school of fish are detected inside the selected sector. The selected sector is displayed with white dashed lines in the horizontal sonar picture. · User setting: This function is used to store the parameter settings for different type of fisheries, or individual user related settings. 302656/A 19 Simrad SH40 · Default setting: Click this button to retrieve the factory settings. 20 302656/A Common procedures COMMON PROCEDURES This chapter presents how to perform the most common procedures on the SH40 sonar.

If you experience problems you think are caused by noise, try to find out which system that causes the noise, and contact your dealer for advice. Cavitation As the propeller blades move through the water, low pressure areas are formed as the water accelerates around and moves past the blades. The faster the blades move, the lower the pressure around it will become. As it reaches vapour pressure, the water vaporizes and forms small bubbles of gas. [. . . ]
