You can make a warranty claim in relation to material and workmanship defects. The warranty does not cover batteries, wear-and-tear parts, wear caused by commercial usage, or accidents.You are only entitled to make a warranty claim if the SIGMA product itself has not been opened without authorization and the receipt of purchase is provided.

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.

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.

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.

Your bike computer can be switched from km/h to mph in the settings menu (under the function “unit”).

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.

All SIGMA SPORT bike computer accessories are available on the market. If your retailer does not stock the replacement you can find the product number in the accessories list and order it from your retailer.

For information on how to change the bike computer/transmitter battery, please see the set-up 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®).

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.

The bike computer measures the voltage of the button cell under a defined load. It can then calculate the cell’s residual capacity based on the voltage dip under this load. The “Low Bat” message is activated when the total capacity falls below approx. 25%.

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.

The speed is displayed up to 199.8 km/h with a wheel circumference set at 2,095 mm.

– Measure the wheel diameter in mm or cm and multiply this by 3.14.
– 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.

The following tire sizes are already pre-programmed into the PURE 1:
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.

The DATA CENTER software can be downloaded from the SIGMA online shop at www.sigma-data-center.com.

No, the new Topline 16 docking station (product no.: 00168) is required for the PURE 1/ATS.

The bike computers come in ‘deep sleep mode’. This prevents undesired energy consumption during storage. To activate the bike computer, press and hold the SET button on the back of the housing for at least five seconds.

The bike computer switches off automatically after five minutes (sleep mode activated) providing that no speed signals are received and no buttons are pressed.

PURE 1 ATS
If the PURE 1 ATS is in the handlebar bracket and the antenna icon is visible on the display, the auto-start/stop function is active.

On setting off, the computer will automatically wake up from sleep mode and switch on. If no antenna icon is visible, you must press a button.

PURE 1
If the PURE 1 is in the handlebar bracket, the computer will automatically wake up from sleep mode and switch on when you set off.

You can use the set-up instructions to help you attach your bike computer.

Set-up videos for the individual computers are however also available.

All SIGMA SPORT products are spray-resistant so that they can also be used in the rain. The bike computer is not suitable for use when swimming and is not machine washable!

To turn on the bike computer please hold the SET-button on the back of the device for five seconds.

– Multiply the wheel diameter in mm or cm by 3.14.
– Measure the distance travelled in one complete turn of the wheel.

Information on how to attach the bike computer (attachment of the handlebar bracket/magnet/wireless transmitter) can be found in the set-up instructions. Set-up videos are also available on our website.

PURE 1 ATS
When using wireless bike computers, avoid ‘cross-over set-ups’ (wireless transmitter attached on the right, bike computer attached to the left of the handlebars).
The wireless transmitter and bike computer should always be attached to the same side.

Please make sure your smartphone supports the required NFC connectivity. Turn on NFC on your bike computer. Open the SIGMA LINK app on your smartphone and choose the bike computer you want to connect. To transfer data please hold your smartphone next to your smartphone’s NFC chip. Be sure not to use any covers on your phone.

Accessories are available in the SIGMA Webshop.
