Standard Method
1. Use the enclosed Allen Wrench to loosen the 
two screws on the Back Plate.
2. Slide the Back Plate between the internal 
padding and the external shell of the helmet. 
3. Adjust the clamp’s location so that the 
microphone is located opposite your mouth 
and then tighten the screws. You may need to 
reposition the Clamp repeatedly until you 
identify the best spot. The microphone must be 
positioned vertically and not horizontally. 
Glue Plate Method
You have the option to glue the Helmet Clamp onto your helmet, 
when the above standard method cannot be used, or in case you 
prefer to secure the Helmet Clamp with adhesive glue. This option 
has been successfully used for a range of high end helmets.
NOTE: While we have no reason to believe that the gluing option might 
negatively aect any helmet, Cardo does not assume any respon-
sibility to that aect, irrespective of its nature and circumstances. 
The Glue Plate is oered as a free option that you may choose to 
use at your own risk and subject to renouncement of any future 
claims.
Caution: This process can be done only once! 
1. Use the enclosed Allen Wrench to remove both 
Allen screws and release the Helmet Clamp’s back 
plate.
2. Determine the location on the helmet where the Hel-
met Clamp must be attached.
3. Adjust the Helmet Clamp’s location on the Helmet so that the 
microphone is located opposite your mouth. 
You may need to reposition the Clamp 
repeatedly until you identify the best spot. The 
microphone must be positioned vertically and 
not horizontally (Be sure to clean the selected area prior to the 
gluing process).
4. Use the pre-moistened Towelette to clean the helmet area where 
you want to install the Glue Plate. Allow to dry thoroughly.
5. Peel the foil cover from the Glue Plates’ adhesive pad.
6. Place the Glue Plate into position according to #3. Press rmly 15 
seconds on all 3 parts of the Glue Plate.
7. The adhesive pad bonds to full strength over the next 24 hours. 
Therefore it is recommended to not use the headset during this 24 
hour period.
8. Fasten the Clamp to the Glue Plate using the Allen screws that were 
previously removed.
 POSITIONING THE SPEAKERS
Speaker A
Speaker B
Attach the speakers to the Velcro inside 
your helmet opposite your ears (short 
speaker cord for the left ear [A] and the 
long speaker cord [B] for the right ear). 
You may want to use the supplied Velcro 
pad.
Using two speakers inside the helmet 
may be prohibited in certain jurisdictions. If this is the case, you 
should tuck away the long corded speaker underneath the helmet 
padding as follows:
