1/u   button and turn on the power.
The fluorescent display tube displays “ALL ERASE” and all memo-
ries will be cleared.

• 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.

The aging mode is provided with the following convenient func-

tions

• 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.

*2 Self protection function during errors:

Function which voluntarily corrects errors which occur during
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 re-
tries, 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 con-
sists of five discs.
