This manual provides detailed operating instructions for the SP70 low frequency fishery sonar.
The Simrad SP70 is a low frequency, long range fishery sonar designed to maximize performance at sea. The system consists of various units including wheelhouse and sonar room components, and supports multiple display modes such as Bow Up, North Up, and True Motion. It features a dedicated operating panel for controlling functions like gain, range, and tilt, as well as a comprehensive menu system for parameter adjustment.
The sonar must never be powered up while the ship is in dry dock because transmitting in open air will damage the transducer.
To prevent inadvertent use of the sonar, you must pull out the mains plug whenever the vessel is in dry dock.
