Does anyone know if it's true that you can press buttons and flash lights and copy a zgemma h2s remote onto a one for all universal URC6440, sounds mad I know but I've seen a few posts saying it works but can't find anything else on the web to say this, it's for my dad so thankful for any help I can get,he's used to the sky remote and finds the zgemma remote complicated or if anyone is using this remote with there zgemma box any instructions would be appreciated , thanks.
