display shown on the screen. We suggest you try both settings and see which one is
better for you. (The reverse display is not affected by the Data Reset command.)

Data input keys
These keys are used to move through submenus in the TRIM function.
The Subtrim menu is used to make small changes or corrections in the neutral
position of each servo. We recommend that you center the digital trims before
making subtrim changes, and that you try to keep all of the subtrim values of as small
as possible. Otherwise, when the subtrims are large values, the servo’s range of
travel is restricted.
The recommended procedure is as follows: zero out both the trims (TRIM RSET
menu) and the subtrims (this menu). Next, mount the servo arms and set up your
linkages so that the neutral position of the control surface is as close to where it
should be as possible. Finally, use a small amount of subtrim to make fine
corrections.

If you’re unhappy with a subtrim value, you may reset
it to zero by pressing the (+) and (-) keys
simultaneously.
