To check the emission of the laser diode during adjustments, never
view directly from the top as this may lose your eye-sight.

As the laser diode in the optical pick-up is easily damaged by static
electricity, solder the laser tap of the flexible board when using it.
Before disconnecting the connector, desolder first. Before con-
necting the connector, be careful not to remove the solder. Also
take adequate measures to prevent damage by static electricity.
Handle the flexible board with care as it breaks easily.

This set uses optical pick-up KMS-262E in the production, but for
the repair, only the KMS-262A is supplied. As a result, two types
of optical pick-ups are used for this set, and the specified values
for the check and adjustment of the laser power vary depending
on the type. Therefore, in performing the check and adjustment of
the laser power, first make sure the type of optical pick-up. The
type of optical pick-up can be identified as follows.
