URC6821: How can I delete a learned key on my Big Button remote?

If you would like to delete a learned function that you no longer require, please follow the procedure outlined below:

1. Press the Device key for the device your learned function operates.
2. Press and hold down the SETUP key until the red LED underneath the POWER key blinks twice (the red LED will blink once then twice).
3. Press 9 7 6. - the LED should blink twice.
4. Press the key to be deleted (e.g. red key) twice.

Additional Information:

• You can delete a learned key by overwriting it with a new learned function.
• If a learned function used in a macro is subsequently deleted, the macro will revert to sending the keys original function.
• If you would like to reset all learned keys in one device mode, after step 1 press the Device key twice.
