Sigma BC1200 wireless problem


Joop de Wit

I bought a Sigma BC1200 wireless computer. It was working OK for about
2 weeks. Then it stopped working.
The strange thing is that all items seem to be working OK:
- The pickup at the wheel ticks and the LED flashes when pressed
- The received at my handle bar also flashes showing that it receives
a signal.
- My computer shows the time and the stopwatch is working, it only
does not react on the pulses. I have cleaned the contacts, reset the
computer by taking out the battery, exchanged the computer with
another one: no dice.

Anyone any idea what can be wrong?

In France, bought the thing in Oz. A bit far for guarantee claims...
