Introduction
Thank you very much for purchasing the Campagnolo ErgoBrain, the most sophisticated road-racing bicycle computer ever made. The ErgoBrain offers some absolutely new functions thanks to the integration with the Ergopower levers. The ErgoBrain is a real competition computer designed for athletes' racing and training needs, but very easy and intuitive to use. This instruction manual explains how to use the ErgoBrain. Please read this manual completely, as well as the installation manual, and store these manuals in a safe place for future reference.

Warnings

Danger !
When riding, always remain aware of your surroundings. Do not give excessive attention to the data displayed. Maintain your focus on the road, traffic conditions, obstacles, etc. Keep all batteries out of the reach of children. In the event a battery is swallowed, contact a doctor immediately. Keep this device out of the reach of children. Always wear a bicycle helmet, bright/reflective clothing, and obey all traffic symbols, signs and laws when you ride.

Important

Periodically check the positions and mounting conditions of the magnet and the speed sensor. Do not expose the unit to direct sun light for extended periods of time. Do not disassemble the main unit and sensors. Do not apply chemicals (thinner or benzene) to the unit. If the contacts on the main unit are shorted, the unit gets initialized (the same as when AC button is pressed). Avoid touching the contacts as it might cause static electricity, resulting in irregular display. Do not use a high-pressure water pump when cleaning Ergopower lever.

Features

The ErgoBrain is the first self-learning computer: Very easy set-up and programming Allows wheel changes during a race without loss of any data Displays sprocket/chainring teeth combination beside showing the chain position With detachable speed and cadence sensors Compatible with all 9 Speed Ergopowers (both 1999 and 2000 ranges)

Format/Initialization

When you use the ErgoBrain for the first time, or afL ter you have replaced the battery, you need to format the unit. Before doing this, find out your front wheel's circumference. Note: From the second time, formatting can be simplified. A press of AC button will retain the former data such as the wheel circumference and information on chainring/sprocket, so just press SET button in each process of formatting. Only for the setting of chainring shift timing, you need to press S/S button.

1. Press AC button.

Note: While holding down SET button, press and release AC button. All display goes on for one second and then it changes to the scale selection screen. Then release SET button. With this operation all the data are erased and the unit is initialized (EEPROM returns to its default state). Perform this operation only when you need to reset the odometer to zero. By initialization, all the former data such as the wheel circumference and information on chainring/ sprocket is erased and returns to the default state.

4. Select cadence on/off.
If you use the cadence sensor on your bike, select [ON], and if not, select [OFF] by the push of MODE button. Push SET button to fix.

5. Select chainring.

Select the number of chainrings (2 or 3) by the push of MODE button. Push SET button to fix.
6. Input chainring's number of teeth. Start with inner chainring.
Push MODE button to increase the digits, and S/S button to decrease. Push SET button to fix, then the screen moves to the next chainring. To return to the former chainring, push S/S and MODE button simultaneously. When chainring's setting is completed, the screen moves to the sprocket's setting. Note: If you have selected CDC sensor [ON], the next sprocket setting is not required; please move to process 8.
7. Input sprocket's (cog set's) number of teeth.
Select the number of teeth from the seven combinations of the cog set. If your sprockets' combination is not included in these cog sets combination, select [FREE] and you can input all the sprockets manually. Note: Sprocket setting should be done individually for wheel A and wheel B. First, input wheel A's sprocket, and hold down SET button. The screen moves to wheel B's sprocket setting. Repeat the same procedure for wheel B.

8. Set chainring's shift timing. Danger!
This operation must be performed as you are riding the bicycle. Therefore, in order to minimize the potential of an accident, this operation must be performed in a wide, open space which is free from traffic or other obstacles. Note: If this is not a first time setting, and if you have not changed the chainrings or adjusted the tension of the front derailleur cable since last time, you can skip this procedure. To skip this, just push S/S button. This completes all the setting and the screen moves to measuring mode. Install the main unit onto your bicycle and ride it. First, shift into the inner chainring and the fifth sprocket. Important: In this procedure, Ergopower shifting should be done slowly and steadily. S/S button should be pushed when the chain has securely shifted to the next chainring. Shift from the inner chainring to the middle. Push S/S button. Shift from the middle to the outer. Push S/S button again. Repeat this operation with the shifting down from outer - middle - inner. When shift timing setting is completed, the screen moves to the measuring screen. Note: If "Error" display appears on the screen, the main unit is not installed firmly onto the bracket, or there may be a problem with the sensor of the Ergopower lever.

To measuring screen

Basic Operation
The upper display shows Current Speed. The lower display shows the selected data. In the lower right the gear indicators shows the current chain positions, and the numbers of teeth of the chainring and sprocket are shown alternately. The unit starts/stops measuring when pedaling starts/stops. This is called Auto Timer (AT) as illustrated in the left part of the drawings in the next page. When the screen is showing Auto Timer, "ATS/S" icon appears on the screen. Independently of Auto Timer (AT), there is Stopwatch (STW) function, which starts/stops measurement when S/S button is pushed (as illustrated in the right part of the drawing in the next page). When the screen is showing Stopwatch, "STW" icon appears on the screen. AT screen and STW screen is independently counted. When either is on the screen, the other is simultaneously continuing in the hidden screen. Thus the ErgoBrain C1 offers two types of measuring modes, Auto Timer with 1-second increment and Stopwatch with 0.1-second increment.

Displays

1. Main data (speed) 2. Sub data (selected data) 3. Chainring indicator 4. Sprocket indicator 5. Number of teeth of chainring/sprocket 6. Pace arrow

Button Operation

The ErgoBrain has two large buttons and two small buttons. The buttons of the Ergopower lever function exactly the same as the large buttons at the side of the main unit. To switch between each function, push MODE button. Note the difference between "just push" and "hold down for two seconds" as in the illustration.

MODE button

Hold down for two seconds Just push
Start/stop of stopwatch Reset operation
AT and STW are reset independently
To start the stopwatch, push S/S button. To stop it, push the button again. To reset the data, push S/S button and MODE button simultaneously. Reset operation affects AT and STW independently. To reset the data of AT screen, do the reset operation while in the function that is marked with "Reset" symbol in the illustration. To reset the data of STW screen, do the reset operation in any function of the STW screen. SET button is used to set the clock time or to change other settings. AC button is used to format the unit. There are two types of returning the unit to the former state - formatting and initialization (See page 4).

Power Saving Feature
When the main unit is left without any button operation or without receiving any signal for about 15 minutes continuously, power supply is shut down and the unit will be in sleep state, displaying only clock. When pedaling is started again or any button is pressed, the unit wakes up and returns to normal display. (The buttons of the Ergopower levers do not release the power saving feature.)

Pace Arrow Feature

The pace arrow indicates whether the current speed is higher or lower than the average speed. In the Auto Timer screen the speed is compared with AV, and in the Stopwatch screen the speed is compared with STWAV (average speed in the Stopwatch function).
Checking Wheel Circumference and Switching between Wheel A and B
Push S/S button and MODE button simultaneously in ODO of Auto Timer screen (sub mode). The current wheel circumference is displayed. By further holding down the two buttons, the display moves from wheel A to wheel B.

Changing Setting

To change the current settings, push SET button in any functions other than clock time, and the display returns to the formatting mode (page 4). After doing necessary changes, return to the measuring display by the press of SET button. (The clock time remains unchanged.)

Self Learning Feature

When CDC sensor is attached to your bike, the ErgoBrain automatically calculates the number of teeth of your sprockets. (This is why you did not have to input the sprockets' teeth in Page 6.) This is called Self Learning feature. Even when the wheel is changed during a race, you only need to do the updating operation (as the explanation below) and the unit continues selflearning without loss of any data. You also need to do the updating operation when you have changed the sprockets (cog set). Updating * Danger ! When riding, always remain aware of your surroundings. Do not give excessive attention to the data displayed. Maintain your focus on the road, traffic conditions, obstacles, etc. Updating should be done while riding your bicycle. You can start the updating with any chain position, but be sure that chain is not skidding but in secure position and the crank is rotating firmly. In any measuring modes, hold down S/S button for more than two seconds, and the unit starts updating. Starts updating

Updating

Note: The unit takes about five seconds, depending on the riding speed, to calculate the number of teeth of each sprocket. While calculating, the wheel icon flashes. Immediately after starting the updating process, the unit might show incorrect teeth numbers, but the system will be instantaneously calibrated and recalculated to the correct numbers. * If CDC sensor is not attached, the self learning feature does not work.

Other Information

When the main unit is detached from the bracket, the data related to chainrings/sprockets will disappear. If SET button is held down for about three seconds in the TM function of Auto Timer screen, the unit automatically falls into sleep state.

Maintenance

Periodically check the position and condition of the speed sensor, cadence sensor and the magnets. When the main unit or the bracket is soiled, clean it with diluted neutral detergent using a soft cloth, and then wipe it dry immediately. Do not use benzene, alcohol or other organic solvent. It will damage the surface.

Replacing Battery

Danger! Keep all batteries out of the reach of children. In the event a battery is swallowed, contact a doctor immediately. When the battery icon starts flashing, replace it with a new one, according to the illustration. Use the recommended battery only. After replacing, format the unit again according to the instructions in page 6.

Troubleshooting

Trouble Check items Remedy The liquid crystal screen is dark and unusual display appears. Was it left for a long time under direct sunlight? It returns to normal by being left in the shade. It does not affect the data. Display response is slow. Was the ambient temperature too low (below 32F, 0C)? It returns to normal when the temperature rises. It does not affect the data. No display appears. Has the battery worn out? Replace it with a new one (CR2032). (After replacing the battery, be sure to press AC button and format the unit again.) Meaningless display appears. If the meaningless display persists, remove and reinstall the battery then format the unit according to the instructions in page 4. Current speed (or cadence) cannot be measured. Check if there is any object on the contacts area. Clean the contacts. Check the position of the speed/cadence sensor and the speed/cadence magnet. Adjust them properly. (Refer to the installation manual.) Check if the cable of the speed/cadence sensor is broken. Replace the sensor set with a new one. The screen does not show the correct chain position or the number of teeth. Check if there is any object on the contacts area. Clean the contacts.

Have you changed the cog set? If CDC sensor is on, do the updating operation according to the instructions in page 13. If CDC sensor is off, push SET button and input the sprockets combination or number of teeth again (page 6). The screen does not match with the shift timing of the front derailleur. Have you adjusted front derailleur or replaced the chainring? Push SET button and set the chainrings shift timing again (page 7). [Error] appears on the screen when setting the chainrings shift timing. Is the sensor wire of one of the ErgoPower lever broken? Replace the bracket set with a new one.
