Version 1.0
The 2006 range DVD Recorder products are repaired centrally.
Defective sets must be identified, labelled and stored for pick-up.
This document gives full instructions for a functional check.
Technical information to repair faulty sets is therefore not provided in this document.
To test in-coming sets the following must be performed:
1. Verify / Reproduce the customer’s problem
2. Verify that set has latest Firmware (see chapter 3) and upgrade if it is not the latest version.
3. Full functional check

Firmware Upgrading & Diagnostic Software
3. Firmware Upgrading & Diagnostic Software
3.1 Firmware Upgrading
A. Preparation to upgrade firmware:
1. Unzip the zip-archive file
2. Start the CD Burning software and create a new CD project (data disc) with the following settings:
File system : Joliet
Format : MODE 2: CDROM XA
Recording mode : SINGLE SESSION (TRACK-AT-ONCE), FINALIZED CD
Note: Long file name is necessary for the preparation of the upgrade disc
3. Place the content of the zip-archive into the root directory of the new CD project.
4. Burn the data onto a blank CDR or CD-RW
B. Procedure to apply the firmware upgrade:
1. Hold the <Record> + <Open/Close> buttons down and Power up the set.
2. The tray opens and set will display:
FORCE DL −>…. INSERT DISC
3. Insert the prepared Upgrade CDROM and close the tray.
4. The set will display:
INIT DSC −> ………. SYS VER −> READ FILES …. DOWNLOAD BE
The whole process takes less than 15 minutes
Note: Do not press any buttons or interrupt the mains supply during the upgrading process, otherwise the set may becomes
defective.
5. When the upgrade is completed the tray will open automatically and the set will display:
REMOVE DISC
6. Close the tray and the set will display:
DONE
7 The set will go into Standby mode.
C. How to read out the firmware version to confirm set has been upgraded:
1. Power up the set.
2. Press <System> button on the Remote control and select {Setup} option
3. Press <Right> button to select {System}
4. The set will prompt you about clearing the Time Shift Buffer
5. Select {Yes} and press <OK> button
6. Press <Down> button several times to select {Version info}
7. Press <OK> button
8. The TV connected to the set will display:
