This section gives an overview of the Extension menu: how to enter the
menu and how to change parameter values.
The Extension menu holds internal parameters and communication
parameters required to achieve the best possible heading accuracy on the
GC80/85 Gyro compass.
The Extension menu is grouped in 8 main categories, named A-1 through
A-8. Each of these main categories has several sub-categories where
parameter values may be set.
All values in the Extension menu are stored in the nonvolatile memory of
the compass.
The Extension menu should not be accessed by unauthorized
personnel. Incorrect parameters may result in irregular operation of
the GC80/85 Gyro compass!
The extension menu can be accessed when any display is shown in the
LCD.
