Set the value so that noise just disappears from the screen. The setting range is -32
to +32 (default: +32).
Note: The setting range is 0 to +31 (default: +12) when the [MODEL] setting is set to

When using the number keys, the indication is first selected as a whole. At this time,
you can toggle between plus "+" or minus "-". Press the 8 key for "-", press the 2 key
for "+". If single digits are highlighted, toggle is not possible. In this case, press the
