Cycle power, if the error persists the MCM will need to
be replaced
On the ADM go into the setup screens -> System->

values
Redefine shot with control parameters within the limits
of the system
Select a different shot or modify existing shot data
If you are certain that the shot is within parameters,
try running the Learn Mode routine found in the setup

reduced control parameters is required.
