  • Page 7: About This Manual

    Target audience This manual is intended for all inexperienced and new users of the Simrad SN90. We assume that you are familiar with the basic acoustic principles of sound in water. We also expect that you have some experience with sonar operation.

  • Page 8: Simrad Sn90

    Before you turn on the SN90, make sure that you have sufficient water depth to lower the transducer! Caution You must never turn on the SN90 when the ship is in dry dock. The transducer may be damaged if it transmits in open air. When the SN90 is not used When you do not use the SN90, turn off the entire system.
  • Page 9 If the transducer is lowered when you turn off the SN90, it is automatically retracted to its upper position. Note If you turn off the SN90 by means of the on/off switch on the Processor Unit you may damage the software and the interface settings used to communicate with external devices.
  • Page 10 Simrad SN90 Quick Start Guide • Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean the transducer. • Do not step on the transducer cables. • Do not damage the transducer cables, and avoid exposure to sharp objects.

  • Page 11: System Description

    System description The Simrad SN90 is a directional high frequency fish finding sonar. Due to the high resolution and long range, the SN90 has proven to be a very efficient tool for both trawlers and purse seiners. Display (The second display is optional.)

  • Page 12: Using Sn90 On Trawlers

    The high frequency bandwidth makes the SN90 ideal for species like pollock, cod and saith. During the search phase, a forward looking SN90 is a very efficient tool for all trawlers. Since the transducer is placed in the vessel’s bow, the SN90 will not suffer from the acoustic noise generated by the hull, machinery and propellers.
  • Page 13 The transducer installation removes the chance to get tangled up or Inspection beams damaged by wires, and greatly reduces the risk of being damaged by objects in the water. Note The SN90 can be delivered with a hull unit. 381297/C...

  • Page 14: General Safety Rules

    Safety is important. The safety precautions must be followed at all times during installation and maintenance work. WARNING The SN90 operates on 115 VAC and/or 230 VAC at 50/60 Hz. This voltage is lethal! You must never work alone on high-voltage equipment! The hull unit is powered by a 3-phase high voltage.

  • Page 26: Getting To Know Presentation Modes And Views

    Context The SN90 presents the echo data in different views. All information from each ping is shown in all the views simultaneously. Each view uses its individual transmit frequency, and you set up the different views with different operating parameters. The behaviour of the echoes in each view is controlled by your course and speed combined with the movements of the target(s).
  • Page 27 • Relevant information about a priority object can be found in the lower left corner of the view. The SN90 transmits in a swath with maximum horizontal opening angle 160°. By means of the function, you can change this opening angle to Horizontal Tx Sector 90, 120 or 160°.
  • Page 28 Simrad SN90 Quick Start Guide At the bottom of the SN90 presentation, select a suitable presentation mode, and activate the Plane view.
