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.
