How to Adjust the Speaker Settings

The optional speaker is available for use with your CH-500/CH-600. By connecting a
speaker, you can "hear" fish echoes, which allows you to move about your ship freely
while fishing.
You can change the following settings for the speaker: output frequency, output band-
width, harmonic pattern and doppler shift filter.
In most cases, these settings are done during the first voyage after installation, and
require almost no adjustment once set.
