I have a 1 4 all remote model urc-7544

Hello, follow this link to download the manual and the codes for your remotes:
http://www.sparky-uk.com/one-for-all-digital-4-urc-7544-universal-remote-control-7-p.asp
just right click and save as on the download links.

if this does not work you can try the search method,
you do this by either holding down the device button eg: TV or if you have one the "magic" button for three seconds, a light should then flash twice to say you have done this correctly.
then press the keys 991 then the power button.
you must now press the channel up key (ch+) possibly upto 150 times while the remote cycles through every code.
Once your tv or device switches off stop pressing the ch+ key and press the power button to make sure it switches back on,
(if you press ch+ too many times you can go back by pressing ch-)
When complete press the magic or device key again to save the settings (light should flash twice to confirm)

Many thanks
Mark
