4-4. Aging Mode
Aging Mode
• Mode which repeatedly changes and plays back discs automati-
cally in the unit.
• It will repeat aging as long as no errors occur.
• If an error occurs during aging, it will stop all servos, motors, etc.
instantaneously, display the error number, and stop operations. How-
ever, the stopping conditions differ according to whether the unit is
equipped with the "self-protection function during errors" described
later.
The function serves to maintain the state of the unit when errors
occur.

Special Aging Mode Functions
The aging mode is provided with the following convenient functions
• Disc setting mode (*1)
• Selection of presence of protection function during error (*2)
• Count function of aging cycle (*3)
*1 Disc setting mode:
5 discs are set before setting the aging mode. This mode makes
the setting of these discs more easy.

mal operations by retries.

ibility.
If this function is provided, and errors can be corrected by retries,
aging will be continued without stopping.
