7. DIAGNOSTIC & TROUBLES AND CORRECTING MEASURES
As soon as you power on this product, it starts self-diagnosis function and show you the result, so it
help you not to perform a failure due to the initial system errors.
When you need to perform self-diagnosis function, just push the 'RESET' button, then it will show you
the diagnosis results. (Note : Do not push 'RESET' button while the system operate). Error messages and
trouble shooting methods of diagnosis results are explained as follows.
