CD ADJUSTMENT

1) Cautions on adjustments
In this product the single voltage (3.3 V) is used for the regulator. The reference voltage is the REFO1 (1.65 V) instead of the GND.
If you should mistakenly short the REFO1 with the GND during adjustment, accurate voltage will not be obtained, and the servo’s misoperation will apply excessive shock to the pickup. To avoid such problems:
a. Do not mix up the REFO1 with the GND when connecting the (-) probe of measuring instruments.
Especially on an oscilloscope, avoid connecting the (-) probe for CH1 to the GND.
b. In many cases, measuring instruments have the same potential as that for the (-) probe. Be sure to set the measuring instruments to the floating state.
c. If you have mistakenly connected the REFO1 to the GND, turn off the regulator or the power immediately.
Before mounting and removing filters or leads for adjustment, be sure to turn off the regulator.
For stable circuit operation, keep the mechanism operating for about one minute or more after the regulator is turned on.
In the test mode, any software protections will not work. Avoid applying any mechanical or electrical shock to the mechanism during adjustment.
The RFAGC and RFO signals with a wide frequency range are easy to oscillate. When observing the signals, insert a resistor of 1k ohms in series.
The load and eject operation is not guarantied with the mechanism upside down. If the mechanism is blocked due to mistaken eject operation, reset the product or turn off and on the ACC to restore it.

2) Test mode
This mode is used to adjust the CD mechanism module.
To enter the test mode.
press [4] + [6] > Reset
To exit from the test mode.
Turn off the ACC and back up.
Notes:
a. During ejection, do not press any other keys than the EJECT key until the loaded disc is ejected.
b. If you have pressed the [RIGHT] key or [LEFT] key during focus search, turn off the power immediately to protect the actuator from damage caused by the lens stuck.
c. For the TR jump modes except 100TR, the track jump operation will continue even if the key is released.
d. For the CRG move and 100TR jump modes, the tracking loop will be closed at the same time when the key is released.
e. When the power is turned off and on, the jump mode is reset to the single TR (91), the RF amp gain is set to 0 dB, and the auto-adjustment values are reset to the default settings.

ERROR CODE LIST

If a CD memory device is inoperable, or operation of such media is stopped by an error, the error mode is established and a cause of the error is displayed by an error code.

Code	Classification	Error code to be displayed	Details and possible causes
10	Servo	Carriage Home NG	The pickup cannot move toward the inner track. The CRG cannot move from the inner track. --> Defective HOME SW; Failure in CRG movement.
07	Servo	TOC reading NG	TOC information cannot be read. --> The partial disk or TOC content is illegal.
11	Servo	Focus NG	Focusing not available > Disc placed upside-down; Stains on the disc; excessive vibration.
17	Servo	Setup NG	The laser output cannot be adjusted. Focus can be easily lost. > Scratches or stains on the disc; excessive vibration.
15	Servo	RF NG	The digital signal from the disc cannot be detected. > A CD-R/RW disc that does not contain data loaded.
12	Servo	Spindle Lock NG Subcode NG RF-amp NG	Spindle not locked. Subcode not readable. Proper RF AMP gain not obtained. > Defective spindle; Scratches or stains on the disc; excessive vibration. > A CD-R/RW disc that does not contain data loaded, or in a rare case, disc placed upside-down. > RF signal error.
30	Servo	Search Time Out	Failed to reach a target address. And, the search became a timeout. > Carriage/Tracking error; Scratches on the disc; Stains on the disc
50	Mechanism	Load NG Eject NG	Disc loading/ejection not completed > A foreign object inserted in the mechanism; Disc jammed.
51	Mechanism	Failure in retried turning for ejection	Disc could not be ejected even after disc turning had been retried. > A foreign object inserted in the mechanism; Disc jammed.
