1. You should conform to the regulations governing
the product (safety, radio and noise, and other
regulations), and should keep the safety during
servicing by following the safety instructions
described in this manual.

2. Before disassembling the unit, be sure to turn off
the power. Unplugging and plugging the connectors
during power-on mode may damage the ICs inside
the unit.

3. To protect the pickup unit from electrostatic discharge
during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY".

4. After replacing the pickup unit, be sure to check the
grating.

5. Be careful in handling ICs. Some ICs such as MOS
type are so fragile that they can be damaged by
electrostatic induction.

For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:
Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

- Error Messages

If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of
the error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from
the users and also for facilitating trouble analysis and repair work in servicing.

(1) Basic Indication Method

1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN
(minutes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO
remains in blank as before.

2) Head unit display examples

Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

8-digit display 6-digit display 4-digit display

ERROR-xx ERR-xx E-xx

(2) Error Code List

Code Class Displayed error code Description of the code and potential cause(s)

10 Electricity Carriage Home NG CRG can't be moved to inner diameter.

SERVO LSI Com- CRG can't be moved from inner diameter.

munication Error -> Failure on home switch or CRG move mechanism.

Communication error between microcomputer and SERVO LSI.

11 Electricity Focus Servo NG Focusing not available.

-> Stains on rear side of disc or excessive vibrations on REWRITABLE.

12 Electricity Spindle Lock NG Spindle not locked. Sub-code is strange (not readable).

Subcode NG -> Failure on spindle, stains or damages on disc, or excessive vibrations.

A disc not containing CD-R data is found.

Turned over disc are found, though rarely.

CD signal error.

17 Electricity Setup NG AGC protection doesn't work. Focus can be easily lost.

-> Damages or stains on disc, or excessive vibrations on REWRITABLE.

30 Electricity Search Time Out Failed to reach target address.

-> CRG tracking error or damages on disc.

44 Electricity ALL Skip Skip setting for all track.

Mechanism

CD On Mech Error Mechanical error during CD ON.

-> Defective loading motor, mechanical lock and mechanical sensor.

A0 System Power Supply NG Power (VD) is ground faulted.

-> Failure on SW transistor or power supply (failure on connector).

Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors).

Unreadable TOC does not constitute an error. An intended operation continues in this case.

Upper digits of an error code are subdivided as shown below:

1x: Setup relevant errors, 3x: Search relevant errors, Ax: Other errors.

Jump Switching

*) • After the [Eject] key is pressed keys other than the [Eject] key should not be pressed, until disc ejection is complete.

• When the key [2] or [3] is pressed during the Focus Search, the power supply should be immediately turned off (otherwise the lens
sticks to Wall, causing the actuator to be damaged).

• In the case of TR jump other than to 100TR, the function shall continue to be processed even if the TR jump key is released. As for
the CRG Move and 100TR Jump, the mechanism shall be set to the Tracking Close mode when the key is released.

• When the power is turned on/off the jump mode is reset to the Single TR (91) while the gain of the RFAMP is reset to 0 dB. At the
same time all the self-adjusting values shall return to the default setting.
