The 850 is not a CCP programmable remote. You have to use the stand alone editor. The 350 is 418 MHz while the 350i is 433 MHz. In reality it is the RFX antenna in the 350i that is 433 MHz.

As stated above, when you setup RF in the Editor, you can select IR Only, RF Only, or IR and RF for EACH device. You could setup the Cable Box, DVD player, and other other equipment under the TV for RF only, and place an emitter on each device. You can go one step further and assign each emitter port to specific devices. If you were in your Cable activity for instance, and you press channel up, it would ONLY send the signal to the emitter port you assigned to the cable box. While you are still within your Cable activity, and you press volume up, it will only route to the emitter port you assigned to your TV or AVR (this assumes you set up your volume punch through and have assigned the emitter port for that device controlling volume).

Also, if you do not have an emitter on the TV, but do have an emitter on the other equipment, you can assign those devices to RF Only, and assign the TV to IR Only. You would leave the Main page set to IR and RF. Once you have everything assigned, the remote will know where to send the signal where ever you are on the remote.
