Sigma computer problem

Try to get sensor and the thing on the fork (forgot the name) as close
as possible without them hitting.

Hi,

I have a Sigma 1600 bike computer. Over all it works pretty well but
I've been having some trouble with the sensor. Sometimes it gets knocked
and won't register anymore. You'd think it would be simple to fix (or I
did) but it seems to be very very picky and after 30 mins of trying
(fiddling around) I've not been able to get register again! Very
frustrating.

Would anyone have any handy hints on what I could be doing wrong with
what should be a very simple procedure?

Thanks in advance

you have the manual??
I guess you do, but here it is anyway
5mm gap max

Bluenose:

Further to other's comments, you need to check first whether the proble
is with the gap between the sensor and the magnet. To do this, you ca
remove the magnet from the spoke and wave it close to the sensor to se
whether computer registers anything. If yes, you need to decrease th
gap between the two piece as much as possible. You may need tryin
different parts of the fork/stays to find the optimal spot. I
necessary, you may need to stack something underneath the sensor t
raise it further out

If you don't get a signal when you bring the magnet near the sensor (i
the first test), then the problem is likely to be with the hardware. I
could be a broken line, broken sensor, bad contacts between the hea
unit and its mount (Sigmas are notorious for their failure due to th
"press and turn" mounting) or even a faulty head unit. In these cases
the warranty could help if there is no sign of abuse

I bought a BC1200 about 2 months ago, and it went crazy after 10 days.
had to return it

Good Luck! Amir

Just to proove that if your sample size if big enough you'll
get every sort of opinion:

We've had two of these computers (on 2 bikes) and apart from
having to clean the contacts after stuffing the 'head' into
a sweaty glove for a week, had no trouble what-so-ever.

I'm a big fan of pulling the magnet off the wheel and waving
it near the sensor. This tends to solve all the computer
problems I've seen, oh and replacing the battery.

Mine had a problem with its buttons. Once the problem showed up
computer started to rest itself over and over and over. And the mod
button worked intermittently. Computer was not subjected to bad weathe
or any harsh use yet. Removing and playing with the mount didn't help

One bad experience was enough for me! Does Sigma give me a loyalty fe
to buy my opinion? I think not. :

you got it working yet?
