Will the Airmar TM275LHW-12 p transducer plug directly to the input of the TZT3 19F and work properly? I’m noting some confusing directions in the install and operating manual of the MFD concerning 1KW transducers.
TZT3 internal sounder has the need 12 pin connection. It should be connected while power is off. After it has been turned on the transducer ID chip should tell the sounder what model it is and it should reflect "TID" or with the model number in the transducer setup in the internal fish finder menu. It should rock and roll very easily for you.
