To make a backup of your personal program list and receiver settings go to

menu -> channel settings -> software manager -> yellow key (System & Channel backup).

Since SW version 02.37: You’ll have to select “channel list” as well as “system settings” to save both.

You’ll get two files on the USB Stick for each backup.

The fileextention for system- and  programmlist- backups is ".si"

To restore your saved settings go to menu -> multimedia -> USB and select your saved settings. Press the red button (update) to load these settings to your receiver.

Since SW version 02.37: go to menu -> software manage and select at "channel list" and "system settings" the option "restore" and select the backup files stored on your USB stick.Wait now until the process is finished.

Principle applies to all upgrade and backup operations: Do not disconnect the receiver from power while upgrade is in progress
