10 SERVICE PRECAUTIONS

10.1. Recovery after the DVD player is repaired.

· The DVD player requires no recovery process after it is repaired; therefore, there is no necessity of using recovery disc.

10.2. Firmware version-up of the DVD player

· The firmware of the DVD player may be renewed to improve the quality including operationability and playability to the
substandard discs.
Make sure to observe the following rules when performing version-up.
Note:
When FROM or module P.C.B. is replaced, carry out the process of firmware version-up.
· The latest firmware required for version-up can be downloaded from TSN-WEB [Support Information from NWBG-PAVC].
When it is finished, use burning software to make up a version-up disc in the form of CD-R.
Note:
Do not modify the file name of downloaded data at random; keep the original file names for disc burning.
Make sure to select normal format instead of image format.
If you may not be able to complete a downloding from the TSN-WEB page, please obtain the file through your local
Panasonic Service Organization.

or not according to the message appearing on the screen.
