That's interesting. The Dish version of the 6.4 IR/UHF Pro remote is silver in color.
The switch in the battery compartment is to change the UHF band. Leave that on A, don't mess with that.
There should be a color key that plugs into the bottom of the remote (front side). I can't see from your pics. The key will be one of the following colors:
Green with the marking 1
Green with the marking 1 UHF Pro
Blue with the marking 2 UHF Pro
Black with no marking or possible the marking UHF
Silver with no marking or possible the marking UHF Pro
If you pull/slide the key out of the remote bottom, you should see a different color or marking on the other side. We are looking for the Green color with the marking 1 on it - sliding that into the remote (facing front) will select IR mode for the remote.
Here is a link to the manual that shows all the different keys =
[Link: my.dish.com]It only shows the Dish versions, which should be the same as the Bell equivalent.
If you don't have a Green IR key on either side of the key installed (and they didn't leave you with the extras - I'm sure they didn't). Try ordering that IR remote I linked to earlier for $22.85.
Lastly, with a working IR remote, go to your System Info screen, press and hold the REC button on the IR remote, this should change the control from a blue UHF box to a green IR box.

All this means nothing however. Someone has to program the Control4 system to work the Bell box.
