How to fight interference Interference is normally identified in the sensor views by readings "jumping" up and down, and deviating from their expected values. Some times you may even be provided with steady readings that are obviously wrong. To fight this disturbance, you can use the Interference Filter provided by the Receiver dialog. Receiver on page 150 When the interference filter is switched on it will remove interference (noise and false echoes) from other echo sounders and sonars in the vicinity of your own vessel. You can also adjust the Detection Threshold (DT) parameter to fight interference. 1 Click the Setup icon under the Main menu to open the Setup sub-menu. 2 Click Receiver to open the Receiver dialog. Receiver on page 150 3 4 5 Activate the Interference Filter, and try different values. Normal ranges up to 1500 meters: If you experience poor reception with the sensors in the sea, try to increase the detection threshold until the data reception appears completely random. If you have interference problems while no sensors have been deployed, try to decrease the detection threshold until you have a stable data reception. c Long ranges above 1500 meters: Initially, use the same strategy as for normal range. Simultaneously, the messages are stored in a number of logging files on the hard disk. If you experience abnormal behaviour, and wish to consult your dealer and/or Simrad, these logging files are very useful. 1 Click the Display icon under the Main menu to open the Display sub-menu. 2 Click Screen Captures to open an operating system folder.
