Chapter 2: Document and product information Chapter contents • 2.1 Document information on page 10 • 2.2 CHIRP Sonar overview on page 11 • 2.
2.1 Document information Further information This document contains important information related to the installation of your Raymarine product. The document includes information to help you: For detailed operating instructions, refer to the handbook that accompanies your multifunction display.
2.2 CHIRP Sonar overview 2.3 CHIRP DownVisionTM overview Sonar interprets signals from the transducer and builds up a detailed underwater view. The transducer sends pulses of sound waves into the water and measures the time it takes for the sound wave to travel to the bottom and back. The returning echoes are affected by bottom structure and by any other objects in their path, for example reefs, wrecks, shoals or fish.

Chapter 4: Cables and connections Chapter contents • 4.1 General cabling guidance on page 20 • 4.2 Cable routing on page 20 • 4.3 Connections overview on page 21 • 4.
4.1 General cabling guidance 4.2 Cable routing Cable types and length Cable routing requirements for the transducer cable. It is important to use cables of the appropriate type and length • Unless otherwise stated use only standard cables of the correct type, supplied by Raymarine. • Ensure that any non-Raymarine cables are of the correct quality and gauge. For example, longer power cable runs may require larger wire gauges to minimize voltage drop along the run.
4.3 Connections overview 4.4 Transducer cable connection Use the following information to help you identify the connections on your product. The transducer can be connected directly to a DownVision sonar module or a DownVision variant multifunction display.

Chapter 5: Pre-installation test Chapter contents • 5.
5.1 Testing the transducer Transducer operation should be checked before installation. 1. Connect the transducer to the sonar module’s transducer connection. 2. Fully submerge the transducer in water. 3. Power up the sonar module and the multifunction display connected to it. 4. Open a Fishfinder application page on your multifunction display. 5. Check that accurate depth and temperature readings are displayed in the Fishfinder application. 6.
Chapter 6: Mounting Chapter contents • 6.1 Dead rise angle on page 26 • 6.2 Mounting the transducer in a hull with a dead rise on page 27 • 6.3 Mounting the transducer in a hull without a dead rise on page 28 • 6.
6.1 Dead rise angle The dead rise angle is the angle of the vessels hull from the centerline. 4 Slope of hull 5 Dead rise angle 25 degrees maximum 1. Calculate the dead rise angle. 1 2. 3. 4 4. 3 2 D12955-1 1 Waterline 2 Centerline 3 Dead Rise Angle 4 Parallel with waterline 5. The dead rise angle should be measured on the outside of the hull from the location that the transducer is to be mounted using an angle finder or similar device.
6.2 Mounting the transducer in a hull with a dead rise When mounting the transducer in a hull that has a dead rise angle the transducer should be mounted following the steps below. Important: Do NOT remove the label attached to the transducer cable as it contains important information. 1 2 3 4 16. With a person inside the vessel, place the top half of the dead rise block over the threaded tube. 17.
6.3 Mounting the transducer in a hull without a dead rise When mounting the transducer in a hull with a flat bottom (no dead rise) follow the steps below. Important: Do NOT remove the label attached to the transducer cable as it contains important information. 2 1 Do NOT overtighten. Overtightening can cause damage to the transducer and hull which may result in water leaking into the hull. 15. Remove any excess adhesive sealant. 16.
6.4 Cored fiberglass hull mounting If installing in a cored fiberglass hull the transducer should be mounted in a non-cored section. Before installing in a cored section of the hull the area around the hole must be adequately strengthened to ensure it is not damaged when tightening the transducer. Important: Installation in a cored hull should only be carried out by a competent marine installer.
