CP370/B164 issue

Dennis,

Please be aware that resetting the sounder module will change the selected transducer. This will not however prevent the fishfinder from operating, but may adversely affect the performance of the fishfinder. It is unclear from your response whether you have used the previously provided command sequence to correctly configure the Fishfinder application's settings to specify that the sounder module has been interfaced to a B164 transducer. Please ensure that this action takes place following any action to reset the sounder module.

Per my prior response, it is recommended that you try not using the Auto frequency feature and instead command the Fishfinder application page/pane being viewed to use the 50kHz frequency ... I am concerned that the sounder module may be incorrectly using 200kHz rather than 50kHz.
