I guess it shouldn't. I went through the user manual using the link above but couldn't see any way of pairing the computer with the sensor. Which makes me wonder if there is any coded pairing mechanism at all. Best would be to ask the salesman at your LBS to verify.
the typical range of the wireless is between 60-80 cm, that's under a yard, the wireless won't affect each other. I have a Bell wireless as does my riding buddy, and we never get any interference.
but as mulveyr mentioned, if you have a higher power light with a blinking mode, the blinking does generate interference thatt's picked up by most wireless bike computers.
