I just bought a new wireless Cateye computer for my Rans V-rex, and then noticed in the setup instructions that the maximum distance between the computer and the transmitter is supposed to be no more than 70 cm, or about 27.5 inches. On the V-rex it's several inches more than that, as I suppose it would be on any recumbent -- even more on a LWB. It does work, at least initially, but now I'm wondering if I'm going to be replacing the batteries about once a week since it's operating at the extreme edge of its range. Can anyone comment on whether this is going to be a problem? Do wireless computers work okay on bents?
