CA1 Course Notes
CA1 Non Volatile Memory Codes
All user setting are contained within the non volatile memory, IC1002 including a number of pre-set
receiver parameters. Although these are pre-set for the model, they can be changed. Under normal
circumstances this would serve no purpose, as the circuitry to preform the various functions may not be
fitted. However, should a data corruption occur, or there is a need to modify the software, the locations
and functions are shown below. At the end of this section an explanation is given on how to set these
codes.
