For example, if the DPT (depth) sentence is set ON but the fishfinder's
transducer is designed to sense temperature and speed only, the depth value
will be transmitted as zero. If you also have an ST60 Depth instrument
installed, there may be confusion between the zero depth sent by the fishfinder
and the actual depth sent by the ST60. Turning OFF the DPT sentence disables
the reading from the fishfinder.
The factory default for all NMEA sentences is transmission ON. Disable the
sentence by selecting the OFF soft key. The following table displays the
available NMEA sentences and their meanings.

The messages will not stop transmitting until after ENTER is pressed. Consult
your NMEA instrumentation documentation to determine which strings
should remain ON.
Note: TheL760/RC Plus outputs the same depth value for DBT and DPT, re-
gardless of the Depth Offset value in Sonar Setup.
