• Set the Gain value using the " +/- " switch using the tables
below as a guideline. Right and left Gain settings are
polarized for direction as shown in Table 6.
NOTE: Gain values depend on many more factors than just
speed, and therefore are best set automatically or by
an experienced operator.
NOTE: Test the response at a sensitivity (Sensi) of five,
because the Sensi setting will scale the Gain settings
(Section 5.1.1). If the booms are not reacting quickly
enough a higher Gain setting will make the boom
respond faster. If the booms are too jerky or unstable,
you must lower the Gain setting or improve the boom’s
mechanical damping.
