2. Functions / Properties
2.1 General
- Current/average speed comparison →
If you are traveling at approximately your average speed, nothing is displayed. If you are traveling quicker than your average speed,
(▲) is displayed; if you are traveling slower ( ) is displayed. This information is displayed in almost all functions, except the basic settings.

14.6 Ava Speed 2.175- Service interval The service interval informs you when you have cycled a specified number of kilometers and a bike inspection is due. This service interval can only be enabled/disabled and pre-configured by your specialist retailer. The device comes with the service interval disabled.
2. Functions / Properties
- Battery status → The battery status of the computer head unit is displayed shortly before the battery runs out. " ☐ low / computer" appears on the display. After changing the battery, only the time needs to be re-set.
- Memory chip → Thanks to an inbuilt memory chip, all total values and settings are permanently stored in the bike computer. This means that you do not need to reconfigure any settings (except for the time) after changing the battery.
- PC compatibility → The bike computer is PC-compatible. After purchasing the SIGMA DATA CENTER software and docking station, you can simply and effortlessly log your total and current values on your PC. You can also configure your bike computer's settings on the PC.

2.2 Special functions
- Fuel saving The BC 12.12/BC 12.12 STS calculates the fuel saving you have made on your bike on the basis of your automobile's average fuel consumption. You therefore quickly and easily discover the savings that you have clocked up on your bike. The bike computer calculates how many liters of fuel you have saved.
- Hiding total values during the trip If the BC 12.12 / BC 12.12 STS receives speed signals, all the total functions (distance, time, and fuel consumption) are hidden on the display. If no speed values are received, the functions are once again displayed.
2. Functions / Properties
- Trip Section Counter (TS) This is a separate distance / time counter that is manually started and stopped. The trip section counter makes it possible to evaluate a trip section or interval training session without influencing the total values for the trip.
2.3 STS features
- Synchronization → Attach the BC 12.12 STS to the bracket – zeros flash for the speed. There are two ways of synchronizing the speed:
-
- → Start cycling – the receiver usually synchronizes with the transmitter after 3-4 wheel rotations.
-
- → Spin the front wheel until the speed values stop flashing.
Removing the BC 12.12 STS from the bracket severs the connection.

Simple line drawing of a bicycle with a red circular arrow indicating rotation (no text or symbols)2. Functions / Properties
- Message "Too Many Signals" → Increase your distance from other cyclists (transmitters) and press any button. Synchronization re-starts. (If the transmission connection is lost during your trip and no longer functions, press and hold the MODE 1 button for more than three seconds to start manual synchronization. "Sync. RESET" flashes on the display)

text_image
Too Many Signals Sync. RESET > 3 sec.- Transport mode → When transported on a bike rack or in the car (if clicked into the bracket), the BC 12.12 STS switches to "transport mode" via an integrated movement sensor. "Transport" appears on the display. Press any button to exit this mode.
3. Settings / Deletion
3.1 Settings
The following settings can be configured: language / unit/wheel size/time/fuel/100 km/total distance/ total time / total fuel (liters) / contrast. Clear diagrams of how to set each of these functions can be found in the enclosed leaflet.
3.2 Determining the wheel size
To measure your speed precisely, the wheel size must be set on the basis of your tire size. To do this, you can:
A - Calculate the wheel size using the formula provided in the wheel size chart.
B - Determine the value from the drawings in the wheel size chart.
C – Take the value that corresponds to your tire size from the wheel size chart.
3.3 Deleting the functions
Please see the diagrams for how to delete the functions.
Please note that the trip section (TS) counter, stopwatch, and countdown timer are not deleted with the current trip values.
4. Important Notes / Troubleshooting
4.1 Technical data
4.1.1 Battery indicator / replacement
Please see the enclosed diagrams for how to insert or remove the battery. After changing the battery in the computer head unit, only the time needs to be re-set.

4.1.2 Troubleshooting
No speed:
- Is the computer correctly fastened into the bracket?
- Check the distance between the magnet and the sensor (max. 5mm) (with STS, max. 12 mm).
- Is the magnet correctly positioned?
Incorrect speed:
- Are two magnets attached to the bike?
- Is the wheel size correctly set?
