Allows tuning of the proportional valve response time and speed for manual control (i.e. when you press the manual raise/lower buttons). You may select a value between 1 and 9 (the default value is 5). You should only need to adjust this setting if you find your implement responds either too quickly, or too slowly, when you press the manual raise/lower buttons. The lower the value, the slower the valve will operate, and the higher the value the faster it will operate. A setting of 9 will provide maximum flow at the valve almost instantly, but this may result in undesirable movements and make lowering to a specific depth more difficult.
