SECTION 1A : INSTALLATION - HARDWARE
1. Install the wheel magnet on a spoke, using a Phillips srewdriver.
2. Position the speed sensor on the fork leg to achieve the correct alignment with the wheel
magnet. If needed, move the wheel magnet. When you have achieved the correct alignment,
pass two zip-ties through the speed sensor and around the fork leg.
3. Re-check the alignment of the speed sensor, and tighten both zip-ties. The distance between
the wheel magnet and the sensor point should be maximum 5mm.
4. Cut off the excess length of the zip-ties.

5. The bracket can be installed on the stem as well as the handlebar. The bracket is pre-assembled in the handlebar position.
6. If you would like to have your computer on the stem, loosen the four screws on the bracket,
rotate the bracket 90 degrees and tighten the four screws.
7. Pass two zip-ties through the bracket and around the stem/handlebar. Cut off the excess
length of the zip-ties.
8. Place the BBB computer in the bracket and rotate clockwise till you hear a “click” sound.

SECTION 1B : INSTALLATION - HEART RATE
The heart rate sensors are integrated in the soft elastic belt. For
a correct heart rate measurement, the belt must be positioned
slightly below your chest, directly on your skin.
1. Make the two contact areas moist before you start your exercise.
2. The chest belt needs to be snug to stay in place. Slide the
buckles to adjust the length of the belt for a snug but comfortable fit.
3. Press the ANT+ transmitter to the elastic belt on the two
push-button connectors.
Maintenance
- Remove the transmitter from the elastic belt after every use
and dry the push-buttons connectors on the transmitter.
Rinse the soft elastic belt under running water after every
use.
- Wash the elastic belt regularly in a washing machine at 30ºC.
Use a washing pouch. Do not spin-dry, iron, dry clean or
bleach the elastic belt. Do not use detergent with bleach or
fabric softener.
- Never put the transmitter in the washing machine!
INSTALLING THE HEART RATE SENSOR
The sensor batteries are pre-installed. When needed, check below illustrations for correct
replacement.
1. Open the battery cover by turning the cover counter clockwise.
2. Insert the battery (CR 2032) with the negative side (- ) facing up for 3 seconds. This will
reset the sensor.
3. Insert the battery (CR 2032) with the positive side (+ ) facing up. Close the battery cover
by turning it clockwise.
Batteries should be disposed of in compliance with local regulations.

SECTION 1C : INSTALLATION - CADENCE
1. Install the cadence magnet on the non drive train side of the crank.
2. Install the cadence sensor on the chainstay.
3. Position the cadence sensor on the chainstay to achieve the correct alignment with the cadence magnet. If needed, move the cadence magnet. The distance between the magnet and
the sensor point should be maximum 3mm. When you have achieved the correct alignment,
pass two zip-ties through the sensor and around the chainstay.
4. Cut off the excess length of the zip-ties.

High Limit / Low Limit
For a healthy and effective training your heart rate should not be too high or too low. Your computer will warn you when you are training too hard or not hard enough. The heart rate shown on
the display will start to flash when you are under or over your limits.
During an exercise test done by a sports doctor your high and low heart rate limit can be determined precisely. There is a simple, less precise, way to determine these values:
High limit = (220(man) / 224(woman)) – age) x 90%
Low limit = (220(man) / 224(woman)) – age) x 60%

To set the most precise wheel size, do a “rollout” test.
(Make sure the tires are at the correct tire pressure)
A. Sit on the bicycle, place the valve of the front
wheel on the floor.
B. Mark the floor at the valve position.
C. While you sit on the bicycle, have a helper roll the
bicycle forward with one revolution of the wheel,
so that the valve is directly on the floor again.
D. Mark the new position of the valve.
E. Measure the distance between the two marks, in
millimeters.
F. Set this value in the DigiBoard computer.

1. During the pairing procedure the computer makes a secured digital connection with the
sensors. Once a sensor is found the computer will show “SPD FOUND”, “CAD FOUND” and/
or “HRT FOUND”, depending on the type of sensors you are using.
During the pairing process the heart rate, cadence and speed symbol will flash in the display. When a sensor is found, the symbol will stop flashing. Before you start using your bicycle
wait until the pairing process is completely finished and the computer display shows the main
screen.
Once sensors are paired the connection is stored in the computer memory. The pairing process
does not have to be repeated before each ride.
The pairing procedure can be repeated manually by pressing the M and F button together for 3
seconds.
Starting the pairing procedure manually is needed when sensors cannot be found or when a later
bought sensor needs to be paired.

SECTION 2C : FIRST TIME SET-UP : HOME ALTITUDE
The altitude in this computer is measured by a pressure sensitive barometer. Not only altitude,
but also changing weather will influence the height showed on your computer.
Before each ride you have to calibrate the altitude to let the computer compare your home
altitude with the current weather situation.
Home altitude can also be described as start altitude. The home altitude is a saved preset for
easy calibration.
Are you on holiday?
Save your start altitude as home for calibration before each ride.
Will your ride start from a different altitude each day?
Check page 27, Advanced Altitude settings, for changing the current altitude.
Calibration of the altitude is described at page 20.
1. Start with the ALTITUDE menu (ALTI GAIN shown in display). Press M button for 3 seconds.
