PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

This set employs a laser. Therefore, be sure to follow carefully the instructions below when servicing.

WARNING!!
WHEN SERVICING, DO NOT APPROACH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION. BE SURE TO OBSERVE FROM A DISTANCE OF MORE THAN 30cm FROM THE SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.

Caution
 Invisible laser radiation when open and interlocks defeated avoid exposure to beam.

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

CAUTION
Use of controls or adjustments or performance of procedures other than those specified here may result in hazardous radiation exposure. This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label is located on the rear exterior. precaution to replace the Optical block (OPTIMA-720AIE) Body or clothes electrostatic potential could ruin the laser diode in the optical block. Be sure to ground the body and workbench, and use care
the clothes do not touch the diode. After the connection, remove the solder shown in the right figure.

CD TEST MODE

  1. How to Activate CD Test Mode
  2. Connect the 62-pin (test) of IC701 (LC72358N-9910) on MAIN C.B to the 31-pin (VDD) by cable.v
  3. Connect the wire of ACC (red) and BACKUP (yellow) of the power supply/speaker connector to DC+12V, then connect Ground (black) to -.
  4. When CD test mode is started, all displays will be lighted as shown in the following figure. 1-2 How to cancel CD Test Mode
  5. Disconnect the cable of 62-pin (test) and 31-pin (VDD) of the MAIN C.B
  6. IC701 (LC72358N-9910) and switch on the power.

CD Test Mode Functions

MODE Keys to operate Display Operations Contents
Start Mode   All lightented   • Start TEST MODE
Search Mode RANDOM TOC READING •  Continual Focus Search (The pickup lens

respeats the full-swing up-down motion)

  • NOTE 1

| • Confirm APC circuit

• Laser current measurement

• Confirm focus error waveform

Play Mode| REP 1| TRACK No.

Playing Time Indica- tion Revel/Ing Indication

| •  Normal Play Back

•  Focus search is contiuned if TOC cannot be read

| • Focus servo

•  Traking servo

• CLV servo

• Sled servo

Traverse Mode| INT| Track no. & Playing Time Indication| •  Pause Status| • Traking servo OFF
Thread Mode|  | All lightened| •  Pick up Move to outer most track

•  Pick up Move to inner most track

| • Thread servo

• Confirm mechanism operation

Gain Switch| 1

(Preset Button)

| All lightened| •    Step 1 : For CD/CD-R

•  Step 2 : For CD-R RF Gain is up against Step 1

•  Step 3 : For CD-R Laser Power Up against Step 2

| • Step 1 to 3 are cyclic

• “Error 03” is indicated if the Disc does not Step 1 match.

  • Do not insert a Disc when confirming the Search Mode
  • Press the PWR button when cancelling Search Mode. Test Mode will be restored when PWR button is pressed once again.
  • Insert the “Test Disc” when operating all modes except search mode.
  • NOTE 1 : There are CD operations are disabled owing to the protection circuit being operated when heat builds up in the driver ICif the focus search is operated continually for more than 10 minutes.
  • In cases, the power supply should be switched off  for 10 minutes until heat has been reduced and then re-started.
