< Suppressing Noise ([CLUTTER] control)
Use the [CLUTTER] controls to remove fine noise across the screen that

available, one for suppressing high-frequency noise and the other for
suppressing low-frequency noise. Turn the [CLUTTER] controls as
appropriate to suppress screen noise.
The setting "0" disables noise suppression. Normally, use the [CLUTTER]
controls at position 3.
