Cautions

About handling the optical pickup and the magnetic head.

-The optical pickup and the magnetic head are structured precisely; therefore, they are very fragile. Be careful not to touch them with the edge of the laser power meter. Do not touch the lens.

-The sensor of the laser power meter is a very fine part. Be careful not to touch it to the optical pickup lens.

-Do not loosen or remove the magnetic head installing screw.

-The focus point of the laser reaches to 356°F. Therefore, avoid adjusting using laser power for a long time because the sensor of the laser power meter may be burned.

-Do not allow the write power to even momentarily reach or exceed 6mW. Doing so will result in damage to the optical pickup.

-Do not set the unit to the laser power adjustment mode with the MD loaded. Doing so may result in damage to the MD.

-Laser diode in the optical pickup may be destroyed by the staticelectricity generated in your clothes or body. Be especially careful with the static electricity.
