Precautions for Laser Diode Emission Check

When checking the emission of the laser diode during adjust- ments, never view directly downwards as this may lead to blindness.

Precautions for Using Optical Pick-up (LCX-2E)

As the laser diode inside the optical pick-up damages by static electricity easily, solder the laser tap of the Optical pick-up flexible board when handling. Also take the necessary measures to prevent damages by static electricity. Handle the Optical pick- up flexible board with care as it breaks easily.

This MiniDisc player is classi- fied as a CLASS 1 LASER product.

The CLASS 1 LASER PRODUCT label is located on the bottom exterior.

Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

Be careful not to apply force on the conductor when soldering or unsoldering.

Notes on chip component replacement

Never reuse a disconnected chip component.
