  • Page 19: How To Adjust The Gain

    1. OPERATIONAL OVERVIEW How to Adjust the Gain The GAIN knob adjusts the sensitivity of the receiver, which can hide noise and other unwanted echoes. A high gain setting increases signal strength and can show exces- sive noise, as well as smaller, hard to detect echoes. A low gain setting eliminates noise and gives a clearer picture, however smaller echoes may also be removed.

  • Page 21: Noise And Interference

    1. OPERATIONAL OVERVIEW Noise and Interference Ultrasonic noise and interference can make it difficult to see the echoes you want to see on the screen. Depending on the cause, your sonar can “adjust” the picture, either by suppressing noise and interference, or by changing the transmission rate. The following sections cover the more common causes of noise and interference.

  • Page 22: Sidelobe Echo/False Echo (Horizontal Mode)

    1. OPERATIONAL OVERVIEW 1.8.3 Sidelobe Echo/False Echo (Horizontal Mode) While the ultrasonic wave is emitted only in the direction set by the TILT control, some emissions are directed outside the main beam. These are called sidelobes. The ener- gy of the sidelobe is weak in comparison to the main beam, but when the water is rel- atively shallow and the seabed is hard, strong echoes are detected by the sidelobes.

  • Page 23: Interference From Other Equipment

    1. OPERATIONAL OVERVIEW 1.8.5 Interference from other equipment While observing the sonar picture, you may encounter occasional or intermittent noise and interference. These are mostly caused by on-board electronic equipment, engine or propeller noise, or electrical noise from other sonars being operated nearby. Typical interference is displayed on-screen in a manner similar to the figure below.

  • Page 24: How To Erase Weak Echoes

The current tilt setting always appears at the top-center of the display, which gives you a clear image of the angle for the scan beam.

  • Page 29: How To Use The Sector Function

    1. OPERATIONAL OVERVIEW 1.13 How to Use the Sector Function In some cases, you may want to restrict the scanning beam to a specific sector in re- lation to your ship.
