Page 7: Important Information
DSM25 can also display temperature, distance traveled, and/or speed. This manual contains important information for installing and operating your DSM25. To get the best results in operation and performance, please take the time to read this handbook thoroughly. Raymarine’s Technical Services representatives or your local dealer will be available to answer any questions you may have. -
Page 8: Emc Conformance
If the transducer cable is accidentally removed while the DSM25 is powered on, remove power from the sounder module, replace the transducer cable, and then return power to the module. As a safety feature, the DSM25 only recognizes that the transducer is connected at power-up. -
Page 9: Product Disposal
The following illustration shows typical cable suppression ferrites sometimes used with Raymarine equipment. To ensure EMC compliance, always use these ferrites, if supplied by Raymarine for use with this equipment. If not supplied by Raymarine, a ferrite is not required for use with this equipment. -

Technical Accuracy The technical and graphical information contained in this handbook, to the best of our knowledge, was correct as it went to press. However, the Raymarine policy of continuous improvement and updating may change product specifications without prior notice. As a result, unavoidable differences between the product and handbook may occur from time to time. -
Page 11: Chapter 1: Overview
This handbook describes how to install the DSM25 Digital Sounder Module and operate it using the A65 display unit. The DSM25 emits and receives sonar signals from a transducer mounted in the water, then interprets and transmits the data to the A65 installed on the console. -
Page 12: What The Sounder Displays
1.2 What the Sounder Displays When you first view the Fishfinder application on the A65, an image representing the echoes received by the DSM is displayed. As time passes this image scrolls from right to left and becomes a record of the data collected. The images at the right hand side of the display are therefore the most recent. -
Page 13: How The Fishfinder Works
Chapter 1: Overview 1.3 How the Fishfinder Works The Fishfinder application uses the DSM25 to process sonar signals from a suitable transducer and provide a detailed underwater view. The transducer located on the bottom of the boat 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. -
