This function cannot completely identify the failure of the transducer. Use this as a guide to see when the
transducer is operating normally.
When there is a chevron in the vicinity of the frequency used after checking the waveform, the operation of
transducer is good.
When there is no chevron in the vicinity of the frequency used after checking the waveform or is flat, the
transducer may be defective.
Take a picture of the bad waveform and contact us or your distributor. (Contact information is on the back cover)
