3 : From end of TOC read to end of last track playback
4 : From end of last track playback to end of first track playback

# : DISC No.

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
reproducibility.
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.

1. Turn ON the power of the unit, set disc to disc table, and per-

form chucking.

2. Remove the power cord from the outlet.
3. To set ADJ mode, connect the TP4 (ADJ) of the MAIN board

to ground, and connect the power cord to the outlet.

In this mode, table rotation and loading operations are not per-
formed because it is taken that the disc has already been chucked.

The same operations are also performed in the following when the
TP4 (ADJ) is connected to ground after turning on the power.
• Direct search (movement of sledding motor) is not performed dur-

ing accessing

• Ignored even when GFS becomes L
• Ignored even when the Q data cannot be read
• Focus gain does not decrease

To set this mode, connect the TP5 (AFADJ) on the MAIN board to
ground, and connect the power cord to the outlet.

When this mode is executed, all title memos recorded will be erased.

• When this button is pressed, “line # No. #” will be displayed. However,
