4.5 RESETTING YOUR HEADSET
If your headset fails to respond despite repeated attempts, you can 
reset your headset by charging it. After approximately 10 seconds, 
remove the headset from the charger and turn it on again. Your head-
set should now respond as expected.
5. GETTING STARTED
5.1  MOUNTING THE HEADSET ON THE HELMET
The Helmet clamp that includes your microphone and speakers must 
rst be mounted on the helmet. Once mounted, the headset unit can 
be attached or detached from the clamp at any time (sec. 5.4).
There are two methods that can be used to attach the clamp to the 
helmet:
Standard Method: Recommended for most helmet types.
Glue Plate Method: Recommended for helmets 
to which the standard method cannot be applied, 
using the Glue Plate included in the box.
Glue Plate
Standard Method: Fastening the Clamp to the 
Helmet 
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 in front of the center 
of your mouth, and then tighten the screws. 
You may need to reposition the Clamp 
repeatedly until you identify the best spot.
If you have purchased a helmet clamp version with 
the corded microphone, please refer to section 5.2.
Glue Plate Method: Attaching the Clamp by way of glue
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. 
Caution: This process can be done only once!
NOTE: While we have no reason to believe that the gluing option might nega-
tively aect any helmet, Cardo does not assume any responsibility 
to that eect, 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.
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 Helmet 
Clamp must be attached.
