  • Page 11: System Description

    Whether it is heavy weather, hard bottom, open waters, weak targets - all echoes are handled by the ST90 due to the fully stabilized and very narrow beams combined with the cutting edge signal processing.
  • Page 12 Simrad ST90 Quick Start Guide The centre operational frequency is 19 kHz, but you can select any operational frequency from 14 to 24 kHz in steps of 1 kHz. The cylindrical multi-element transducer allows the omnidirectional sonar beams to be tilted electronically from -10 to +84 degrees. This allows you to automatically track schools of fish, and to observe the whole water volume around the vessel.

  • Page 13: General Safety Rules

    Safety is important. The safety precautions must be followed at all times during installation and maintenance work. WARNING The ST90 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.
