Back Space Use the backspace key to delete the last
character or number entered.
Using the scroll
wheel Use the scroll wheel to alter the current value.
Clockwise increases the value, anti-clockwise
decreases the value. The scroll wheel is usually
used for values that highly variable, such as the
center frequency settings.
Directional arrows Use the directional arrows to select discrete
parameters or to alter values by a coarser
resolution than the scroll wheel. Left/down
decreases the value, right/up increases the
value. The directional arrows are usually used
for values that are of a discrete nature, such as
selecting a memory location.
