DSM25s are intended for recreational depth finding and fish finding purposes. Echo sounder systems require an appropriate Raymarine transducer unit and inter-connecting cable. Depending on the type of transducer connected, the 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. For full details on system integration, please refer to the handbook supplied with the A65 display. Safety Notices This equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so can result in personal injury and/or navigational inaccuracies. In particular: WARNING: Electrical Safety The DSM25 contains high voltages. Adjustments require specialized service procedures and tools only available to qualified service technicians ­ there are no user serviceable parts or adjustments. The operator should never remove the cover or attempt to service the equipment. Make sure the power supply is switched off before making any electrical connections. WARNING: Transducer Cable Removing the transducer cable from the rear of the sounder module while it is switched on can cause sparks. Only remove the transducer cable after power has been removed from the A65 display unit, which supplies power to the DSM. As with any electronic device, be sure the sounder module is mounted where it is well ventilated and free from gasoline fumes. 8 DSM25 Owner's Handbook 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. CAUTION: Ultrasonic Energy The transducer transmits ...
