The servo circuit of this model is designed to be adjustment-free and the adjustment value and disc distinction (CD-DA, CD-R and CD-RW) etc. is
adjusted by the IC. Therefore the adjustment is performed at each TOC reading. The adjustment conditions in the IC of each servo can be monitored
in this test mode.
1. How To Start The Mode
Starting method of the test mode differ depending upon the type of disc being used. This is because the adjustment values of each
servo also differ depending upon the type of disc.
When using the CD-DA or CD-R
1) Short-circuit TEST LAND and OPEN/CLOSE SW land.
2) Insert the AC plug to the power outlet and install the CD-DA or CD-R disc.
3) Press the PLAY and STOP buttons in this sequence and read the TOC.
When using the CD-RW
1) Short-circuit the TEST LAND and OPEN/CLOSE SW land.
2) Insert the AC plug to the power outlet and install the CD-RW disc.
3) Press the PLAY, STOP and DSL buttons in this sequence and read the TOC. The LCD should display “CD-r” at this point.
Note 1: If the TOC cannot be read, “ERR” has appeared on the LCD. The following step 2 and 3 can be verified even if the “TOC” cannot be
read.
Note 2: By repeatedly pressing the DISPLAY/ENTER button all the LCDs light up and the “TOC” display is repeated.
Note 3: By repeatedly pressing the DSL button the LCD “CD-r” and “CD-d” are repeated.
When the LCD displays “CD-d” ™CD-DA, CD-R is selected.
When the LCD displays “CD-r” ™CD-RW is selected.
Note 4: The test mode is canceled by disconnecting the AC plug and remove the soldering of short land.
2. DISC distinction (confirmation of the FE waveform)
This mode enables you to perform a confirmation of the disc distinction.
Confirmation method
Press the DSL button and select “CD-d” or “CD-r” (Refer to Note 3).
1) Install the disc.
2) Press the MODE button.
The LCD will change as follows:
Example: Test disc: TCD-782, DISC type select: CD-d Judgment value: 68, Measurement value: 37 CF
* All numerical values are displayed in HEX.
What disc the IC has selected can be understood according to the judgment value.
The decision standard of IC is as follows.
The state of the FE waveform can be also understood from this judgment.
Judgment value Measurement value
0 < Judgment value< 10
10 < Judgment value< 32
32 < Judgment value< C8
C8 < Judgment value

3. Confirmation of Sled movement
By pressing the F.SKIP or B.SKIP button continuously during the TEST MODE, it is possible to transfer the pick-up to either the outer
side or inner side.
4. Confirmation of the RF level
Test point: RF and VC (Vref)
Test disc: TCD-782
Confirm that the RF waveform is as shown below.
VOLT/DIV: 200mV
TIME/DIV: 0.5us
5. Confirmation of Tracking balance
Test point: TE and VC (Vref)
Test disc: TCD-782
Press the DSL button while playing the test disc and confirm the TE waveform is as shown below.
VOLT/DIV: 200mV
TIME/DIV: 2ms
6. Confirmation of each servo
It is possible to confirm the adjustment value of each servo by repeatedly pressing the MODE button while the disc is playing.
The switchover sequence is as stated below.
Confirmation mode off ™Focus Bias (FB) ™Tracking Balance (TB) ™Tracking Gain (TG) ™Tracking Error Offset (TEO) ™
Focus Gain (FG) ™Focus Error Offset (FEO) ™Confirmation mode off
Example: Tracking Error Offset (TEO) Adjustment value: 03
