Notes:
• When the "I" cursor reaches the "+" end, it
jumps back to "–". At the same time, COARSE is
incremented by one step to enable a continu-
ous adjustment. The reverse takes place when
the "I" cursor reaches the "–" end.
• When L or M is kept pressed for a second
or more, the "I" cursor moves faster.
