Contrast
The contrast of the display may be adjusted to 10
levels (10 = highest contrast). The setting is stored
when the system is turned off.
Adjustment is local to the control unit you adjust. At
high temperatures, not all levels are available due to
automatic temperature compensation.

Other relevant settings are described under STANDBY mode in
this chapter.
Response
The Autotune function in the AP26 and AP27 is so refined that
80-85 % of the boats will need no further adjustments of the
steering parameters. On some boats, however, or at particular sea
conditions a fine tuning of the steering parameters may improve
the performance of the autopilot.
The Response control allows you to make this fine
tuning. It can be set to seven levels. Level 3 (default)
has the values of Rudder and Counter Rudder
parameters set by the Autotune function. If no
Autotune is made (not recommended) the level 3
values are the factory default values.
A low response level reduces the rudder activity and provides a
more “loose” steering.
A high response level increases the rudder activity and provides
a more “tight” steering.
A too high response level will make the boat start S-ing.
Range: 1 – 7
Default: 3
