In addition to these two screens, the A-2000 also uses audible tones to signal fatal errors.
These are especially useful if a hardware failure prevents the display from working. Each
audible error code consists of a long tone followed by one or more short tones, and finally
another long tone. The specific error condition is indicated by the number of short tones:
