The bias set value is displayed by hexadecimal notationin the 64 steps.
Display range of set value 80 to bF
Default value (center value) of setting is displayed as“9d”. When the value larger than the default value isdisplayed, it means that the higher bias value is set to themachine. When the value smaller than the default valueis displayed, it means that the smaller bias value is set tothe machine.

When the mode display appears on the LCD, and when thePLAY key is pressed in the STOP mode, the LCD shows thecenter value at first. Then the display changes to the set valuewhich is set by the automatic adjustment when thedisc starts rotation.
2 Focus bias control by the manual control
The focus bias value can be set to any desired value bypressing the F. Skip key or B. Skip key during the focusbias check mode.
The 64 steps can be set in the range from 80 to bF.(Center value: 9d)
Make an attempt to change the focus bias using theF.Skip key or B.Skip key while observing the RFwaveform on an oscilloscope, and confirm that the RFsignal is maximum at the default value (the value beforestarting the manual operation).When the maximum amplitude is confirmed at the defaultsetting, the automatic adjustment works satisfactorily
2) Tracking Balance
When the machine enters the tracking balance checkmode, the following display appears on LCD.
Tracking balance set valueTracking balance
The servo circuit of this model is designed to be adjustment-freeand is automatically adjusted inside IC. However, the adjustmentconditions inside IC of the focus bias, tracking balance andtracking gain can be monitored using the test mode.
1. How to Start the Test Mode.
1) While the main power is OFF, set the OPEN/CLOSEswitch (S801) to the CLOSE (ON) position.
* Alternately, shorting the short land near S801 puts theswitch (S801) to the CLOSE (ON) position.
2) Insert the AC plug to the power outlet.3) Press PLAY key , then power on, all LCD light turn on.4) While all LCD light turn on, keep pressing the PLAY
MODE key and short the TEST LAND (TP1) more thanone second.
5) When all LCD lights turn on in step 4), it indicates testmode has started up.
Note) • Once test mode is started, OPEN/CLOSE switchcan not be accepted.
2. Focus Search Mode
The focus search operation can be checked using this mode.
How to start the focus search mode:Press the STOP button when the machine is stopped (STOPmode).If the STOP button is pressed again, the focus searchoperation is stopped.When a disc is inserted while the machine is in the focussearch mode, the disc does not rotate (focus servo is notlocked ON) but the search operation is repeated.
3. Focus Bias, Tracking Balance and TrackingGain Check
Selection of either the focus bias check mode, trackingbalance check mode or the tracking gain check mode can bemade by pressing the PLAY MODE key. As the PLAYMODE key is pressed, the check mode changes in thefollowing order.
Check mode OFF ™ Focus Bias ™ Tracking Balance™ Tracking Gain
When the mode display appears on the LCD, and when thePLAY key is pressed in the STOP mode, the LCD shows thecenter value at first. Then the display changes to the set valuewhich is set by the automatic adjustment when thedisc starts rotation.

Tracking gain Tracking gain set value
The tracking gain set value is displayed by hexadecimalnotation in the 16 steps.
Display range of set value: 40 to 4FDefault value of setting (center value): 48
1 Tracking gain control check by the manual control
The tracking gain can be set to any desired value bypressing the F. Skip key or B. Skip key during thetracking gain check mode.
The 16 steps can be set in the range from 40 to 4F.(Center value: 48)
When any attempt is made to change the tracking gainusing the F. Skip key or B. Skip key while observing theTEO waveform on an oscilloscope, the tracking gainchange can be confirmed as follows.
a) Traverse waveform amplitude change
• Test point: TEO & VC
When the tracking gain is changed during the traversemode, the waveform amplitude change can beconfirmed.
Note) The manual control of the focus bias, tracking balanceand tracking gain can be operated only when the testmode has started up. Microprocessor performs all itemswith automatic adjustment during the normal CDplayback mode so that the manual operation is notpossible. Even when the level setting is made during themanual operation in the test mode, the set values arereset when the machine exits the test mode, and themanually set values are not memorized too.
4. Display of Jitter Change Value
The jitter value is displayed during the focus bias checkmode.The “00” display is equivalent to the jitter amount when aglass disc is played back. The display value shows the actualjitter deviated from the “00” value. The jitter value isdisplayed in the 256 steps from 00 to FF.
