• 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.

Special Functions in Aging Mode

1. Disc setting mode:

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 dur-
ing normal operations by retries.
If this function is not provided, all operations will be stopped
without retiring. It is suitable for checking errors with low re-
producibility.
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.
