How to installing the software
All software is installed from CD-ROM. These are supplied by another disc, respectively. When disc was put in the player,
software is installed automatically. And disc comes out of the player, after fi nished. The sequence to install is “Key
reassignment” fi rst and, next, is “Background”.
Entering Version and region code
Caution: This information is confidential and may not be distributed. Only a qualified service person should reprogram the mono board.
Reprogramming is limited to 25 times.
When the counter reaches 25, reprogramming is not possible anymore and the region code change counter
must be reset by means of the Diagnostic Software.
Reprogramming will be done by way of the remote control.
Put the player in stop mode, no disc loaded.
Press the following keys on the remote control.
<PLAY> followed by numerical keys <2>, <7>, <4>
The display shows “-----------“
Press now successively the following keys
