Why is the bike computer displaying no or incorrect speed?
No speed displayed:
– Is the computer correctly fastened into the bracket?
– Are the contacts on the bracket/bike computer oxidized/corroded?
– Has the sleeve been pushed over the magnet?
– Has the clip-on cover (bearing the word SIGMA) been mounted facing outwards (this can possibly make the gap between the magnet and the sensor too large)? – Image of power magnet
– The gap between the magnet and the transmitter is too large max. 5 mm for the standard magnet and max. 12 mm for the power magnet.
– Is the magnet still magnetized? To test, hold the magnet against a metal object. If the magnet is not attracted to the object, it is no longer magnetized.
– For ATS and/or STS bike computers, check the battery status of the speed transmitter.Incorrect speed displayed:
– Are two magnets attached to the spokes?
– Is the magnet correctly positioned? The magnet should always be positioned parallel and centrally to the transmitter.
– Is the wheel size correctly set? To set the wheel size, please see the operating instructions or the section “Entering the wheel size”.
– For STS speed transmitters and bike computers with automatic second bike detection, is the speed transmitter set to the right bike? -
Are additional accessories needed to transmit and evaluate the trip data?
The trip data can be manually input directly into the software or automatically transmitted using the optionally available docking station.
The docking station not only enables you to automatically transmit data but also to conveniently configure your bike computer via your PC.
It can be purchased from the SIGMA online shop at www.sigma-data-center.com or in store from your specialist retailer.
-
Can I change the battery myself without voiding the warranty?
All SIGMA SPORT bike computers come with a battery compartment, which can be opened and closed by the user with the aid of a coin or a tool (supplied). When changing the battery, always note the position of the O-ring placed on the cover to ensure that the bike computer remains watertight.
-
Why is my display reacting more and more slowly/getting darker and darker?
The bike computer’s display can change in very high or low temperatures. In very high temperatures, the display gets darker; in very low temperatures, the display reacts more slowly. As soon as the temperature has cooled down or warmed up, the display returns to the original state. The display’s temperature range is -10°C to +50°C.

Maintenance and care of your SIGMA product
Your SIGMA SPORT bike computer is a measuring instrument that must be handled carefully.
After a prolonged period of use, especially if the bike and/or bike computer is/are stored outside, the contacts on both parts should be checked for corrosion. In the event of slight corrosion, you should carefully clean the contacts. Store your bike computer in a cool, dry place. After a prolonged winter break, we advise you to check the batteries in both the computer head and the transmitter(s). Although the power consumption during storage is extremely low, temperature fluctuations can impair the battery quality. When changing the battery, always use branded goods.
When cleaning the bike, remove the bike computer from the bracket. When using a high-pressure washer, avoid spraying the bike computer at close range. Ideal scenario: remove the bike computer from the bracket.
