...it seems. Bought an A4+ recently, basic 4-functions analogue wireless. Does appear to work OK for me except for one thing. It shuts down into power-saver mode after a few hours, and does not wake up even when you start riding. Unless you press a button that is. Problem is, I ride a lot at night when I can't look at the computer, even though it's in place on the bike, so I don't think to press the button at the start. So the odometer doesn't increment and my monthly tally is going to be way out... I was about to complain, first to Wiggle, then to VDO, but I thought I'd better RTFM first, not wanting to make a fool of myself, and sure enough it says: So it's doing exactly what it says on the tin, I appear to be stuffed. If the receiver switches itself off, it can't start up even if it receives a pulse from the wheel. I'll just have to remember to press a button every time I start out. Unless someone knows of a workaround. What I want is, not to go into this sleep mode until a much longer time has elapsed - say, a week. Rather that and use the battery up a bit faster. I know I should have stuck with wired, that's what everybody recommends. But I like the tidiness of the wireless option. I have a VDO 'C+' series, the more pricey one with a digital transmitter, on a different bike: this works fine and doesn't have this problem. But the "C+"s don't seem to be so easy to come by at the moment, so I went for the cheaper option.
