Troubleshooting
Problems with the CC1
Problems with the CC1 as part of a 9770 system may occur in the following areas:
•The CC1 itself
•Setup files (also known as configuration files)
•Peripheral devices connected to the CC1
•DOS operating system
A log is recommended for keeping track of changes made to the system. The log should document the change made, why it was made, the date it was made, and the person responsible for the change. This log will help in troubleshooting any errors that may occur. It also makes it easier to identify errors that might have been caused by the change from other types of errors.
