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 opera-
tions. 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.
