Indications of Errors during Startup
If an error is detected during the boot sequence, the following requirements must be met:
• Master muting should not be canceled.
• An error status should be notified to the user.
The indication method differs, depending on where an error was generated. See the table below.
Note: If there are several errors whose error codes are to be indicated on the LCD display, those error codes are added.
Example: USB + DIT = 0x0008 = 0x000C
