Find dvd code to use universal remote control on technika 108?

codes for devices are different from one universal remote to another,there is sometimes a codescan feature in universal remotes that allows you to try every code available to that remote if you have tried all the listed codes in the remote manual and none work . if none of this works, you have to try another universal remote until you find a brand that works for your device. there are smart remotes that can learn new devices, but you have to have the original device remote to teach it and these remotes are more expensive.
