1st Restore Defaults to get the unit to factory defaults and test  ...

If this issue persists try adjusting the Sensitivity  ... itís not uncommon to need a different Sensitivity selection for different frequencies  ...

A good general rule for 2d Sonar Sensitivity is to increase Sensitivity until there is too much clutter on the screen and then back it off a little  ...

Also when moving sensitivity up the screen does not change no returns or clutter? Maybe I've got the wrong transducer for the 440/490 frequency. It's a xtm 9 25 t.THANKS!
