SAFETY INFORMATION

CAUTION:USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

- Safety Precautions for those who Service this Unit. When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable results.

Caution: 1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept. 2. During repair or tests, do not view laser beam for 10 seconds or longer.

CAUTION

WARNING

Where in a manufacturers service documentation, for example in circuit diagrams or listsof components, a symbol is used to indicate that a specific component shall be replaced onlyby the component specified in that documentation for safety reasons, the following symbol shallbe used:

This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repaircomplex products such as those covered by this manual.Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty.If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do soand refer the repair to a qualified service technician.

This product may contain a chemical known to the State of California to cause cancer, or birth defects or other reproductive harm.Health & Safety Code Section 25249.6 - Proposition 65

WARNING!The AEL (accessible emission level )of the laser power output is less than CLASS 1 but the laser component is capable of emitting radiation exceeding the limit for CLASS 1.A specially instructed person should do servicing operation of the apparatus.

Laser diode characteristicsWave length : 785 nm to 814 nm

Maximum output : 1 190 W(Emitting period : unlimited)

Additional Laser Caution

Transistors Q101 in PCB drive the laser diodes.When Q101 is shorted between their terminals, the laser diodes will radiate beam.If the top cover is removed with no disc loaded while such short-circuit is continued, the naked eyes may be exposed to the laser beam.

DANGERDanger of explosion if battery is incorrectly replaced.Replace only with the same or equivalent type.

7 Make sure screws and soldering scraps do not remain inside the product.

Please check that neither solder debris nor screws remain inside the product.

8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.

Damaged power cords may lead to fire accidents, so please be sure that there are no damages.If you find a damaged power cord, please exchange it with a suitable one.

9 There should be no spark traces or similar marks on the power plug.

When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.

a Safe environment should be secured during servicing.

When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely.

5.2 DIAGNOSIS FLOWCHART

- How to detect the cause of the trouble involving the PND unit and the Main unit

If the Main unit returns to the normal operation after replacing the PND unit, the PND unit is defective, basically.If the Main unit returns to the normal operation after replacing the Main unit, the Main unit is defective.

The cases are shown as in the following.

[Case] When the PND unit and Main unit do not start; Connect only PND unit to PC to check if the PND unit starts up by pressing the power switch. -> When the PND unit starts up, the Main unit is defective. -> When the PND unit does not start up, the PND unit is defective.

[Case] When the source sound is not generated; -> The Main unit is defective.

[Case] When the guide sound is not generated; Replace the PND unit to check if the sound is generated. -> When the sound is generated, the PND unit is defective. -> When the sound is not generated, the Main unit is defective.

[Case] When RGB_LED does not light up; Replace the PND unit to check if it lights up. -> When it lights up, the PND unit is defective. -> When it does not light up, the Main unit is defective.

- How to detect the cause of the trouble involving the GPS IF unit

[Case] When TMC signal became unreceivable; Replace the TMC unit to check if it becomes receivable via the air. -> When receivable, the TMC unit is defective. -> When not receivable, check if the P901on the main unit is damaged. If the P901on the main unit mentioned above is; -> Damaged, replace the fuse. -> Not damaged, connect the TMC to check the high-side switch output of the GPS IF unit. If the voltage of the high-side switch output mentioned above is; -> not 14.4 V, the GPS IF unit is defective. -> 14.4 V, the PND unit is defective.

[Case] When GPS became unreceivable; Replace the GPS antenna to check if it becomes receivable. -> If the GPS is receivable, the GPS antenna is defective. -> If the GPS is unreceivable, replace the PND unit to check if the GPS becomes receivable. If the GPS becomes; -> Receivable, the PND unit is defective. -> Unreceivable, the GPS IF unit is defective.

[Reference] How to operate the Main unit without PND unit1. Connect the sensing pin DSENS in the main unit to the GND.2. Discharge BUP sufficiently before pressing the Eject button to start the Main unit.(RGB_LED blinks.)

[Reference] How to check the battery.1. Charge the battery fully.2. Start only PND unit to measure the duration of time until each Caution indicated below appears.3. Compare the measured duration times with the Table 1.

5.3 ERROR CODE LIST

- Error MessagesIf 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.

(CD-R/RW)

50 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.
