RC Key Fob for CES-3
Cruise Mode = Button 1
Radio Display = Button 3

Button 2 = Sport Mode
Button 4 = Open Valves
Buttons during operation
By pressing the buttons 1, 2 or 4 the device will switch between the different
modes. In cruise mode (button 1), the valves open at higher engnie power.
In sport mode this already happens at lower backpressure. Button 4 open the
valves permanently.
The internal radio transmitter is tuned to 88.1 MHz. It can display
information on the radio‘s display. With button 3 you can switches between
different screens. So you can display the current mode, the pressure or
overall status. Setup functions are also possible using the radio display.
See the following pages for more information regarding usage.
Radio Display Details
Showing informations on the radio display requires an RDS-enabled radio set. Different radios will
have a different behavior and the informations are displayed delayed. Some devices have a an
option to set the RDS function to fixed or variable. If possible choose variable.
The FM status light flashes when the internal FM transmitter works and the controller transmits
on 88.1 MHz. Find the radio station on your radio and save the frequency to a station button.
The internal radio transmitter does not transmit audio signal. When frequency ist set correctle,
the radio is muted and there is also not any noise to hear. The internal radio transmitter is
switched off once the control switches into standby mode.
If this frequency is occupied by a local radio station, pressandhold button 3 and 4
simualtaneously for aprox. 2 seconds to switch to the alternate frequency 89.1 MHz. Now the
FM status light flashes twice. Holding this two buttons will switch between the two frequencies.
A short press to button 3 will swop between various information. Thus, the currently selected
mode, the pressure in the exhaust system and the overall status can be displayed. These
possible informations, however, are depending on the current software version.
Setup by Remote Control Key Fob
The controller can be configured extensively. Some parameters can also be set with the RC key
fob. To do this, ensure that the radio can display information of the control unit (see above).
Press andhold buttons 1 and 2 simultaneously until SETUP appears in the radio‘s display. The
key fob buttons now have the following meaning:
backward/minus = Button 1
Esc/back/Abort = Button 3
Button 2 = forward/plus
Button 4 = Enter/confirm/save
With software version 3.011, you can set the following parameters: cruise mode, sports mode,
favorite, language and the type of exhaust system. All buttons have to be pressed briefly.
Press button 2 to move to the first parameter. Cruise appears on the radio‘s display. Press
button 2 again to go to the next parameter: Sport. Press button 4 to edit this parameter. The
display shows 80 mbar. This is the pressure at which the valves open during operation when
sport mode is selected.
You can decrease the value with button 1 key or increase the value with button 2. Once the
desired value is displayed press button 4 to confirm or button 3 to cancel the operation. The
procedure is the same for Cruise mode.
Another parameter you can set is the favorite. This is the mode in which the control unit starts.
You can decide between cruise, sport and open mode.
The language is also adjustable. At current you can choose between English, German and
Italian. The fifth and last of adjustable parameters is the type of exhaust system. It must
match the installed exhaust system (see multi sound).
Capristo appears in the radio‘s display for a few second, when you exit the setup with button
3. Then the control unit returns to normal operating mode.
With the Windows program Capristo Control Center various parameters can be set via
bluetooth. To do so contact the manufacturer.
Multi Sound
Exhaust systems with several valves are able to generate more than two different sounds. For
these special systems the multi sound mode was developed. The quieter electric valve is
thereby connected to the plug-1, the louder valve to plug-2.
The key operation of a multi sound system is almost identical to that of a normal exhaust
system. Select the appropriate mode with button 1, 2 or 4.
Additionally, you can choose whether each mode is to be set as Sound-1 or Sound-2. Press and
hold button 1 for about two seconds to select Sound-1. Press and hold button 2 for about two
seconds to select Sound-2. On the radio‘s display appears a short a notice, if the frequency of
the internal radio transmitter is properly set.
Training the RC Key Fob
The key fob being part of the scope of supply was already linked with the control device (training)
at the factory. A training is required for new or additional key fobs. It is possible to link up to 7 key
fobs to the control box. Key fobs no longer used can be erased. The switch for teaching and
erasing is unvisible in the lower left corner of the case (see the circle in the image on the first
page) and must be operated with a magnet.
Key fobs cannot be erased separately. In order to erase all key fobs hold the magnet for 10
seconds on the housing were the hidden magnetic switch is located. The RC light goes on.
Please wait at least 10 seconds before removing the magnet. The RC light flashes until all key
fobs are erased.
For training a new key fob, shortly hold the magnet on the hidden position. The RC light keeps on
illuminating. Press briefly button 1 on the key fob. The RC light goes dark. Press button 1 again.
The RC light flashes until the new key fob has been stored. The key fob is now ready for use.

Advices for mounting:
1. The Solenoid-Valve develops heat. Mount it in a spot where the influence of heat isn't damaging
2. Do not place the solenoid valve inside the airbox, otherwise contaminated air could get into the
3. Place the controller in a dry place to prevent moisture entering the case.
4. Solenoid and controller must not be placed within spitting distance, beacuse the solenoid's
magnetic field could influence the controller (the key-fobs are added and deleted with help of a
magnetic field!).
5. Controller with German TUEV certificate will be delivered with an implemented "City-Mode" (in the
city the controller automatically invokes the cruise mode and closes the valves).
