AMU Use

3.4.6. Running RESUME and UPDATE
3.4.6.1. Canceling running
All the operating modes LEARN, IMPROVE, MONITOR and UPDATE can be stopped and
started at any time without significant effect on monitoring performance, by pressing the
CLEAR button (and providing the correct password). Subsequent restart of AMU can be
achieved by selecting RESUME from the main menu, which will cause AMU to continue in its
incomplete mode at the point of interruption. Thus, if it is necessary to stop AMU for any
reason, it can be restarted without affecting any existing data.
3.4.7. Advanced use
It is possible to customize the behavior of AMU by adjusting various settings. As usual a
valid password must be supplied before the Edit Settings menu can be entered.
The following table summarizes the settings that can be changed together with their
significance. It is recommended that the original values of each setting be recorded prior to
changing them. After changing certain settings it may be necessary to relearn the motor.
