BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostat-

During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.

NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc refl ective surface by the objective lens in the optical
pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher

than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be

Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
• Strong
viscosity
Unleaded solder is more viscous (sticky, less prone to fl ow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
