Subject: Upgrading the unit for improving the compatibility with amplifiers of
other companies that are conformable to the IEEE1394 standard.

Symptom: The DVD-5900 is incapable of reproducing sound signals via the
IEEE1394 connection when it is connected to other company's amplifiers that are
conformable to the IEEE1394.
Solution: Upon claim please apply the following modification to your
customer's unit for improving compatibility with other manufacturer's models that
are conformable to the IEEE1394.
Caution:
After upgrading, the DVD-5900s is capable of playing back audio signals after
connecting other company's amplifiers that are conformable to the IEEE1394.
However, please keep in mind that it does not guarantee the complete
compatibility in performance, function and the quality.
Note: When performing the upgrade, it is necessary to have a Personal
Computer, Check Jig (Amplifier conformable to the IEEE1394) and others that
are exclusively used for upgrading.
