Two types of optical block assembly: XDH-421(RP) (A-1837-582-A) and XDH-422(RP) (A-2218-177-A) are available. Check the
package version of your PDW-HD1550 (referring to

For package version 1.63 or later: XDH-422 (RP) (A-2218-177-A) is recommended. It can also be XDH-421 (RP) (A-1837-582-
A).

For package version earlier than 1.63: XDH-421(RP) (A-1837-582-A)

To replacement to the XDH-422(RP) (A-2218-177-A), package version 1.63 or later is required.
When the XDH-422(RP) (A-2218-177-A) is attached to a firmware drive unit other than above and the optical drive system is
adjusted, a message “ADJUSTING...FAILURE” appears during the LD IL adjustment.

Package version 1.63 or later is compatible with both types of optical block assembly shown above.
