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 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.

1. Turn ON the power of the unit. Press the 

[   OPEN/CLOSE]

2. Change the 

[COMMAND MODE]

 switch (S901) on set to 

[CD1]

.

3. Press the 

[AGING START]

 button of the remote commander

for aging mode (J-2501-123-A).

4. When the disc set mode is set, the 

[     ]

 and 

[   ]

 LEDs blink.

5. Rotate the 

[DISC/CHARACTER]

 dial. The slits (No. 60, 120,

180, 240, 300) for setting the discs will come forward. Insert
the discs into these slits. Do not set the discs in other slits.

6. Set whether the self-protection function during errors is

equipped with the unit. Press the 

[REPEAT]

 button. If “RE-

PEAT” is displayed on the fluorescent indicator tube, it means
the function is provided. If “REPEAT” is not displayed, it
means the function is not provided.

7. Press the

· button.

8. The

· LED blinks, the aging mode is set, and aging is

started.

9. If errors occur during aging, the error number will be displayed

on the fluorescent indicator tube. (Refer to the following table
for the details of the errors.)

10. Aging will be repeated as long as no errors occur.
11. After each aging cycle, the number displayed on the fluores-

cent indicator tube will increase.

12. To release this mode, press the

1/

u

button.

form chucking.

2. Remove the power cord from the outlet.
3. To set ADJ mode, connect the ^¡ pin of IC501 (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
^¡ pin of IC501 (ADJ) is connected to ground after turning on the
power.
• Direct search (movement of sledding motor) is not performed

during accessing

• Ignored even when GFS becomes L
• Ignored even when the Q data cannot be read
