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.
However, 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.
