Logitech Duo probs when adding new mouse?

Hi
I have the Logitech Cordless Elite Duo (wireless keyboard and mouse) and it has one receiver for both.
I am getting the Logitech MX700 and I was wondering if there would be intereference between the original receiver (now only for the keyboard) and the new receiver (for the MX700)...

Any help would be great.
Thanks

Don't hold me to it, but I believe that because the two products are multi-channel and encrypted, that they should not interfere with one another.

the MX700 also has a channel switch, which you need to put the mouse and reciever on the same channel (which you should obviously pick a different frequency than your keyboard)

Ah ok!
channel switch solves it, thanks
