I didn't bother using the special cover  - and I haven't had any radio 
interference problems. I think the "bubble" cover is for wedging in an
older modem. The toshiba modem works just fine.  I have used it with
a variety of telecommunications programs.

I do read the toshiba bbs regularly - and the RFI complaint has come up a 
few times. A solution was also suggested.  Radio Shack sells some magnetic
toroids that you can loop your phone cord and power cords through. They
are supposed to be really cheap - and they completely cut out the unwanted RFI.
