Frequently Asked Questions - BC 16.12 STS Plus CAD SIGMA

How to wake up the computer after delivery?

Hold down the MODE 1 and SET buttons for 5 seconds to exit deep sleep mode.

How to calculate wheel circumference?

Use the formula from the Wheel Size Chart or directly measure your tire circumference. The value must be between 500 and 3999 mm.

What to do if no speed is displayed?

Check that the computer is properly seated in its bracket, that the distance between the magnet and sensor does not exceed 5 mm (12 mm for STS), and that the magnet is correctly positioned.

How to synchronize the STS model?

Place the computer on its bracket and start. After 3 to 4 wheel or crank revolutions, synchronization occurs automatically. You can also spin the front wheel or pedals until the display stops flashing.

How to activate the backlight?

Press the SET and RESET buttons simultaneously to turn the backlight on or off. The backlight turns off automatically after a few seconds of inactivity to save battery.

How to use the stopwatch?

Use the MODE 2 button to access the stopwatch. Press SET to start/stop, and RESET to reset.

How to clear total values?

Total values (total distance, total time) can be reset via the settings menu. Refer to the manual's diagrams for the exact procedure.

How to adjust the display contrast?

Access the Settings menu by holding down the SET button. Use the buttons to navigate to the Contrast option and adjust it to your preference.

What does the 'Too many signals' display mean?

This indicates that the computer is receiving interference from other transmitters. Move away from other cyclists and press a button to restart synchronization.

How to change the battery?

Remove the computer from its bracket, open the battery compartment on the back, replace the old battery with a new CR2032 battery observing polarity, then close. Only the time will need to be reset.

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.

Automatic detection of the second bike

The switchover between bike 1 and bike 2 occurs automatically. You simply need to carry the necessary accessories with you. For the wired device, the universal bracket with appropriate cabling should be purchased as an extra. For the wireless device, a second speed transmitter should be purchased and set to bike 2 (see set-up instructions for further details).

2. Functions / Properties

The total values are only separately displayed for bike 1, bike 2 and bike 1 + 2 once a second bike has been added. If only one bike is used, only the total values for the first bike are displayed.

Light manager Simultaneously press the SET and RESET buttons to switch the light function on/off. The display lights up by pressing any button; the bike computer changes to the respective function when the button is pressed again. On STS devices, the light function is disabled during synchronization (max. 5 minutes). Avoid using the backlight unnecessarily to save the battery!
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.

• 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. Functions / Properties

2.2 Special functions

• Hiding total values during the trip If the BC 16.12/BC 16.12 STS receives speed signals, all the total functions (distance, time) are hidden on the display. If no speed values are received, the functions are once again displayed.
• Showing and hiding cadence functions If the BC 16.12 / BC 16.12 STS are used without the cadence transmitter, all the cadence functions (cadence / 0 cadence) are hidden for this trip after five minutes.
• Trip section (TS) counter 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 16.12 STS to the bracket - zeros flash for the speed and cadence. There are two ways of synchronizing the speed / cadence:
• 1. → Start cycling – the receiver usually synchronizes with the transmitters after 3-4 wheel / pedal rotations.
• 1. → Spin the front wheel or turn the pedals until the speed / cadence values stop flashing. Removing the BC 16.12 STS from the bracket severs the connection

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)

• Transport mode When transported on a bike rack or in the car (if clicked into the bracket), the BC 16.12 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 1 / wheel size 2 / time / total distance 1 / total distance 2 / total time 1 / total time 2 / 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. 5 mm) (with STS, max. 12 mm).
• Is the magnet correctly positioned?

Incorrect speed:

• Are two magnets attached to the bike?
