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.
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.
Please note that switching from km/h to mph automatically changes the time from 24h format to 12h format. The wheel size is also automatically converted. For information on how to make the switch, please see the operating instructions.

On using quality batteries for one hour per day or 7,300 km per year at an average speed of 20 km/h (batteries available from SIGMA SPORT®).
STS transmitter range
| Speed: | 90 cm |
| Cadence: | 110 cm |
| Heart rate: | 110 cm |
ATS transmitter range:
| Speed: | 70 cm |
If the battery in the wireless transmitter is cold or low, the range may shorten.
Various electrical and electronic components or devices can interfere with transmission. This also applies to battery-powered lights, and in particular LED lights. The pulsing of the LED (fast, regular switching on/off of the LED) can generate a frequency, which can in turn interfere with the bike computer’s transmission.
The frequency generated can be isolated within the LED light so that there is no interference with the transmission.
Sigma LED lights are diode suppressed meaning that they do not generate an interfering electromagnetic field. You can resolve problems by attaching the LED light to the handlebars approx. 10 cm from the bike computer.
A pure voltage measurement (e.g. with a multimeter) without any battery load does not provide precise information about the (residual) capacity of a button cell battery. The battery can still have a voltage of 3 V without load but of only 2.4 V when under load, e.g. if the wireless receiver is operating.
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 to ensure that the bike computer remains watertight.
- Computer is not correctly slotted into the sensor´s bracket.
- Sleeve has moved over the spoke magnet.
- The distance between the spoke magent and sensor is too big.
- Contacts on the bike computer must be cleaned. Bike computer is faulty.
- There is a break in the sensor cable.
- For ATS bike computers, please check the battery status of the speed transmitter.
Incorrect speed displayed:
- Is the magnet correctly positioned? The magnet should always be positioned parallel and centrally to the sensor. A mark on this indicates the area that the magnet has to pass.
- Is the wheel size correctly set? To set the wheel size, please see the operating instructions or the section ‘Entering the wheel size’.
- Measure the distance of a full wheel rotation.
Conduct the measurement as follows:
STEP 1 Stand your bike upright and position the wheel to which you want to attach the sensor so that the valve is directly on the ground. Ensure that the tire is fully pumped up in accordance with its usage conditions. Mark the position of the valve on the ground with a line or adhesive tape.
STEP 2 Push the bike forwards in a straight line until the valve is back on the ground again after a full rotation. Again, mark the position of the valve with a line or adhesive tape.
STEP 3 The distance between the two marks on the ground is your wheel circumference, i.e. your wheel size in millimeters.
16“-18“-20“-22“-24“-26“-27“-27.5“-28“-29“-700C
The wheel circumference (roll circumference of the tire) can also be set manually within a range of 500 mm to 3,999 mm.
