Nice work! How did you stumble on this?Edmund said:Those R15 owners with RF remotes and antennas, plug them in and do the following:
2. press and hold MUTE & SELECT for two blinks
3. enter 9-6-1
4. press CH UP
5. enter the last 6 digits of your receiver ID #
6. press SELECT
You should now be able to control the receiver by RF.
