hey, i just bought a wireless shimano flightdeck computer about 2 weeks ago and the bike shop i got it from put it on for me it worked good until now. i took the wheel off and put it back on and all of a sudden its not displaing the speed. the magnet and the sensor havent moved and if so i cant tell where to move them back, the bike store i bought it from is far away so wont be able to get it htere for a while. i dont know what to do help me out.

I do not have a wireless flightdeck, but I think the problem might be that the unit is turned off.

According to the manual " To activate the trip distance group, press Mode button to (TIM) and press ST/SP button to activate."

I hope this is a simple fix for you. Let us know.

that does start the trip distance and everything but thats not the problem, the speed period isnt showing, the clock and the stopwatch works but when i spin the wheel the speed just says 0.0, i dont know this really sucks.

I had a similar problem. Make sure that the mph/kph indicator is flashing. If not, you need to press the left button until it flashes. That should activate the system properly.

between the magnet and the sensor, often times during the removal of a wheel the sensor will get pushed aside just enough so that the two are no longer close enough.

Just on the off chance. The head unit goes into a sleep mode when not in use. To 'wake' it, just press the 'B' button briefly to wake up the unit. The display will then show all read outs briefly followed by a display of which bike no. it's set to (if it's a 6501 head unit) followed by the gear display and then the default display. The speed should be displayed as the unit is activated..

Just a thought.

Couple of things to check - first, as already suggested, check the distance between the sensor and the magnet - I generally try to keep that from 3-5mm. Next, check the radial position of the magnet on the spoke relative to the sensor (if I remember correctly, there are indicators on the sensor which show you where the magnet is supposed to go). Next, check the angle of the sensor relative to the display head - you want the sensor to point at the underside of the display head - also, make sure there isn't too much separation between the display head and the sensor (not generally an issue unless you have a large bike, or mount the sensor near the hub). Finally - if all that fails, try replacing the battery in the sensor - maybe the unit sat on the shelf for a while or something, and the battery is dead...
