Hi, My Sigma BC 1009 STS does not seem to pair with the transmitter. Once it is mounted in its bracket the MPH flashes but will not stop flashing and will not display any riding information at all....

If the computer is new return it. If not and you have tried a fresh battery on the sending unit and mounting the sending unit as high as possible on the fork, there's really nothing else to try. Check warranty.

I just bought the lense. The Firmware on my Canon Rebel T1i adjust automatically to my two Canon lenses, but show that I have to download firmware for the Sigma lens. Where do I get that?


There is no update for the Sigma lens since it is inter-related to the update you do for your camera, however you can check if there is any update available for your Canon Camera and it should automatically fix any issues you have with the lens/camera.

Hope this is helpful.

Thank you for contacting FixYa

Real magic by sigma designs dvd station gives error mssg " an instance of the driver may already be in use..." Is this a DMA issue?

Not likely a dma, but but a windows issue. Go the operating panel and then to system and remove all drivers for the device. On re-booting, it will locate a driver and correct the situation. Have the driver disk ready if it asks for it.

My Dell XPS M1330's internal speakers are not working, the audio utility claims that it is producing sound. I am running windows vista, and the sigma tel audio codec is my sound driver.

#1 Flash the BIOS to the most current version. #2 Run diagnostics from the F12 menu (Or Power plus FN key) see if the speakers work in the diagnostic. If they work in diags, there is no hardware issue, only a software issue. If you get no sound in diags, try a pair of headphones, if you still get no sound, then it is a hardware problem. If you only get sound in the headphones, then the microswitch that disables the speakers is stuck. #3 is sound works in diags then you have a problem with the audio driver or speaker configuration (Audio muted etc)

A: For Sigma issue:

The Sigma EF-500 flashes have very small chromed contacts for the batteries. Even though they may not look corroded, they may not power up or conduct enough power to fully cycle up. Use a polishing tip in a dremel or an ink eraser tip to clean the internal wire contacts and the flat contacts on the door. I use dielectric grease on a q-tip to apply a coat to all contacts and cleaned battery terminals to minimise future issues.

It sounds like a CPU chip incompatability issue. Sigma has that problem sometimes but are usually very good about rechipping at no cost (at least for Nikon-mount lenses). What did they say when you asked them?
