1.8 Clutter
Low level noise can cause your display to look “cluttered” with unnecessary dots. These are

clutter.

as appropriate using S or T, then press the ENT key.
4. Select [Clutter] using S or T, then press the ENT key. This
will open a pop-up window.

dual transducer configuration go to the next step.

[7].
