• 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

5 discs are set before setting the aging mode. This mode makes
the setting of these discs more easy.

*2 Self protection function during errors:

Function which voluntarily corrects errors which occur during nor-
mal operations by retries.
If this function is not provided, all operations will be stopped with-

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

*3 Aging cycle count function:

Functions which displays the number of agings carried out on the
Fluorescent indicator tube  in numbers. One aging cycle consists
of five discs.
