NOTE: Optional speaker pads are provided to boost the speaker volume if needed by 
bringing the speakers closer to your ears. 
To use, simply place the speaker pad between the Velcro pad in the helmet 
indentation and the speaker.
5.5 POSITIONING THE MICROPHONE 
Locate the spot on the internal padding of the helmet, opposite your mouth, 
where the microphone will be placed.
1.  Peel the cover from the adhesive Velcro pad and place it on the chosen 
location opposite your mouth.
2.  Attach the microphone to the Velcro, as shown in illustration.
3.  If there is any excess microphone cable, tuck it under the cheek pads.
5.6 REMOVING THE SRCSYSTEM™ FROM YOUR HELMET

IMPORTANT: Make sure not to pull on the Antenna connector.
2.  Lift and push the collar’s arch from the front helmet area to carefully remove 
the SRC-System™ from the helmet.

5.7 WEARING AND REMOVING THE HELMET
The electronic components of SRC-System™ are safely embedded inside an 
Acoustic Collar. To avoid discomfort while you put on your helmet or while 
removing it, we recommend that you proceed as follows: 
1.  Expand the helmet opening by rmly holding the chin straps and pulling 
them forcefully apart. 
2.  While pulling the straps apart, slide the helmet 
over your head.
3.  To remove the helmet, proceed along the same 
lines by rst pulling the straps apart and then 
pushing the entire helmet upwards.
NOTE: Your SRC-System™ Acoustic Collar is designed for maximum comfort. 
However, since it contains an entire electronic kit within, it will have a slight a bulge. 
Therefore, putting your SRC equipped helmet on or taking it o may feel dierent 
than what you are used to with a standard Acoustic Collar. Remember: The more 
you pull the helmet straps apart when putting on your helmet or taking it o, the 
smoother the process will be, allowing the Acoustic Collar to soften.
5.8 CLEANING THE SRCSYSTEM™ ACOUSTIC COLLAR
To clean the SRC-System™ Acoustic Collar, rst make sure the USB connector is 
tightly closed. Use only a slightly damp cloth. Avoid soaking the Acoustic Collar 
with water or any other uid. Never submerge it and refrain from letting water 
come in contact with the speakers or the microphone. Allow the unit to dry at 
room temperature.
