8.2 HOW TO UPDATE THE DSP FLASH ROM BY PLAYING BACK A CD

[Purpose]
By referring to this section, rewrite the DSP Flash ROM when required. Rewriting is instructed through service information, etc.
By playing back a CD-R on which a DSP program is recorded, using a normal CD player, rewriting is possible.
[Tools to be used]
Please use DVD player based on MTK system (DV-270, 370, 373, 575K, 280, 380, 383, etc. ) ,Mitsubishi system (DV-59AVi,
868AVi, S969AVi, 668AVi, etc. ) or Fujitsu system (DV-343, 444, 545, etc.) DO NOT use DVD player based on ST system
(DV-353, 454, 250, 400, 555K, 260, 363, 464, 466, 563, etc. ) The factory confirmed that DVD players based on ST system
cannot send the correct data to the VSX unit using the update disc.
You can check the base system of our DVD players on the firmware version list at PSN web (Niis)
• Coaxial cable or Optical cable

[Connections]
Connect this unit and a player, as shown in the figure below.
[Preparations]
Burn the DSP flash ROM firmware (.wav file) to a CD-R disc using commercially available burning software.
It is necessary to select the writing format to "For music player", not "For PC data".
Note:
Depending on a burning software, data on a CD-R may not be worked for updating the DSP flash ROM.
If the HDMI indicator does not flash when playing back a update disc by following procedure 5, the disc is not able to use for
updating.
Burn the DSP flash ROM firmware to a CD-R disc, using other burning software. (The burning software that operation check
is finished: Record Now !)
[Note]
• Do NOT disconnect the AC cords of this unit nor the CD/DVD player while rewriting is in progress.
• The "OK" indication displayed after updating means the checksum on the flash ROM is OK.
If the "OK" indication is not displayed, updating has not been completed.
Note that confirmation with audio check or version check is insufficient for checking if updating has been completed.
If you set the unit to STANDBY OFF without confirming of "OK" indication on the FL display, be sure to perform the updating
procedures again.
