C120W with AirMar P66 Not Recording Speed

ProLine23Sport,

The DSM30 is incorrectly responding with a list of 1kW transducers to select from rather than a list of 600W transducers to select from. Should a DSM Reset have been commanded from the Fishfinder settings and should the list of 600W transducers (will include the P66) not be displayed, then it would indicate a fault within the DSM30's circuitry necessitating that it be sent to Raymarine’s Product Repair Center to be bench checked / serviced or replaced with a CP370.
