4. Put disk to be checked into the tray.  Close the tray

using either the [OPEN/CLOSE] or [PLAY] button on
the unit or on the remote. The disk will automatically
be distinguished and error rate measurement will
begin.
Fig. c will display:

1

Inserted disk’s inner parameter (For DVD, Layer
0, initial address)

2

Inserted disk’s outer parameter (For DVD, Layer
0, final address)

3

Inserted disk’s Layer 1, initial address.

4

Inserted disk’s Layer 1, final address.

Depending on the contents of the inserted disk, 3
and 4 above may not be displayed.
Once the error rate measurement has started, if the
largest value resulting from the first three measure-
ments has a value of 2000 or less, and all values in
the "Uncorrect" row are 0, the message "CHECK :
OK" will be displayed on area 

5

.

If the largest value is greater than 2000, the mes-
sage "CHECK : NG" will be displayed on area 

5

.

The message "OK" or "NG" will continue to be
displayed without change until the measurement is
stopped. The error rate measurement will continue
to be updated.

5. "Correct" and "Uncorrect" in Fig. c:

(1) For DVDs the following will be displayed:
PO1st-Correct count; PO1st-Uncorrect count;
PI1st-Correct count; PI1st-Uncorrect count;
PO2nd-Correct; PO2nd-Uncorrect count;
PI2nd-Correct count; PI2nd-Uncorrect count;
PO3rd-Correct count; PO3rd-Uncorrect count.
The above ten numerical values will be displayed for
each 80 ECC block.

(2) For CD/VCDs the following will be displayed:
C1-Correct count; C2-Uncorrect count.
The values for these two items will be displayed
every 7350x4 frames.
For VFD, the following will be displayed:
PO1st-Correct count; (C1-Correct count for CDs).

measurement

6. To end the ERROR RATE measurement, press the

[OPEN/CLOSE] button on either the unit or the
remote.  After the display has ceased, press the
[POWER] button on either the unit or the remote to
shut off the power.
