2. Correction of Errors
[When due to tape deck]
Stopped while tape aging operation with the “  ” displayed state.
[When due to CD]
Press  x ,  DISPLAY , and  Z  together to display the error code.
• Display of number of mechanism errors
Move the stick to the left and right to display “CDM Err Count *”.
* is the number of mechanism errors.
• Display of mechanism error
Move the stick to the left and right to display “CDM E**D##$$%%!!”.
Move the stick up and down to send the error number.
**
: Error number 00 is the latest error.
The larger the number, the older will the error be. (Maximum 9)
##
: FF is the mechanism error after mechanism initialization ends.
$$
: Judge from the first digit of the error number. (Don’t care the second digit.)
When the error number is 1 or 2, it indicates mechanism error in tray loading between the stocker position and behind it.
%% : Judge from the first digit of the error number. (Don’t care the second digit.)
When the error number is 2, it indicates mechanism error in the up/down movements of the stocker.
!!
: Judge from the first digit of the error number. (Don’t care the second digit.)
When the error number is 2, it indicates mechanism error during switching of the clamper and mode.
• No DISC error display
Move the stick left and right to display “No Disc Count *”.
* means the number of no discs.
• No DISC error display
Move the stick left and right to display “No E**D##$$%%00”.
Move the stick up and down to send the error number.
**
: Error number 01 is the latest error.
The larger the number, the older will the error be. (Maximum 3)

VIDEO CD COLOR-BARS MODE
On this mode, the data of the color-bars signal as a picture signal and the 1kHz sine wave signal as a sound signal are output by the
mechanism control microcomputer (IC502) for video CD signal check. When measurement of the voltage and waveform on the VIDEO
board, perform it in this mode.
For reference, the color-bars signal can be observed at J302 (VIDEO OUT) and the sound signal can be observed at J101 (VIDEO/MD
(AUDIO) OUT) using an oscilloscope.
1.
Connect the lead wire to both ends of the land of SL503 of the VIDEO board.
2.
Press the  ?/1  button to turn ON the power. Press  FUNCTION  button to select CD.
3.
After 2 or 3 seconds later, connect the lead wire.
4.
After measuring, remove the lead wire connected.

Precaution
1. Clean the following parts with a denatured alcohol-moistened
swab:
record/playback heads
pinch rollers
erase head
rubber belts
capstan
idlers
2. Demagnetize the record/playback head with a head demagne-
tizer.
3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound to the
parts adjusted.
5. The adjustments should be performed with the rated power sup-
ply voltage unless otherwise noted.

5. The adjustments should be performed in the order given in this
service manual. (As a general rule, playback circuit adjustment
should be completed before performing recording circuit adjust-
ment.)
6. The adjustments should be performed for both L-CH and R-CH.
7. Switches and controls should be set as follows unless otherwise
specified.
