It was so hard to find the codes for this remote on the internet, so when I manage to recover the manual, I decided it was time to share it. This no-frills remote control can be bought at around SGD$3 in the budget shops in Singapore. I have verified that the codes works for Supertel URC2002-P but not the URC-24B and RM-1001 (supports 10 Remotes), do feedback to me if it works for you so that I can update the status.
E.g. To program TV1 for Sony, press SET and TV1 simultaneously, press 129. The LED should go off if the correct code is entered, else you will see the LED turned on or blinks. Test by pressing the POWER button while pointing the remote to the TV.
