: Part Replacement

: Cleaning

  (For cleaning, use a lint-free cloth danpened with pure isopropyl alcohol.)

Use the following table as a guide to maintain the mechanical parts in good operating condition.

1. The laser light having wavelength 650 nm is emitted from the objective lens. BE CAREFUL SO THAT THE LASER

LIGHT DOES NOT ENTER DIRECTLY INTO YOUR EYE.

2. The semiconductor laser may be easily damaged by electrostatic charges. When handling the pickup, take care so that

the electrostatic charge is not generated.

3. The semiconductor laser may be easily damaged by overcurrent. Use the power supply unit which does not give any

spike current when the power is turned on and off.

4. Carefully remove the dust and dirt from the objective lens with the lens blower.

When handling the objective lens, take due care so that it is not contaminated with fingerprint, etc. If the objective lens

is contaminated, impregnate the cleaning paper with a small quantity of solvent (isopropyl alcohol), and gently wipe to

clean.

5. The ozone layer depleting components (ODC) are not used in the production process for the product.

frame.

9. Remove three screws (L) which install the terminal PWB.

10. Remove seven screws (M) and one screw (N) which install the

terminal block.

11. Remove three screws (P) of the display PWB.

12. Remove two screws (Q) of the decorative leg.

13. Push out the middle pin (R) of the setting leg in the direction

opposite to insertion. (Two places)

14. Remove two screws (S) which install the main PWB under the

mechanical unit.

15. Remove three screws (T) which install the volume PWB of the

front panel.
