from the charger and turn it on again. Your G4 should now respond
as expected.
5. GETTING STARTED
5.1 MOUNTING THE G4 ON A HELMET
The Helmet clamp that includes your microphone and speakers
must first be mounted on the helmet. Once mounted, the G4
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.
6
scala rider® G4 PowerSet
Glue Plate Method:
You have the option to glue the Helmet Clamp onto your helmet
when the above standard method cannot be used, or if 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
negatively aect any helmet, Cardo does not assume any responsibility
to that eect, irrespec tive of its nature and circumstances. The Glue Plate
is oered as an 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.
3. Adjust the Helmet Clamp’s location on the Helmet so that the
microphone is located opposite the center of
your mouth. You may need to reposition the
Clamp repeatedly until you identify the best
spot. (Be sure to clean the selected area prior to
the gluing process).
4. Use the pre-moistened Towlette 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 Plate’s 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 we recommend not using the G4 during this 24 hour
period.
8. Fasten the Clamp to the Glue Plate using the Allen screws that
were previously removed.
If you have purchased a helmet clamp version with the corded
microphone, please proceed as follows:
5.2 ATTACHING THE CORDED MICROPHONE TO A
FULLFACED HELMET
If you are using the corded microphone version, you must rst make
sure your helmet clamp is attached to your
helmet as described in previous section (5.1).
Clean the exact spot on the internal padding of
the helmet, opposite your mouth, where the
microphone will be placed.
a. Peel the foil cover from the adhesive Velcro
pad and place the Velcro pad on the chosen
location opposite your mouth.
b. Attach the microphone to the Velcro, as shown
in photo.
c. When done, tighten the screws of the clamp.
5.3 POSITIONING THE MICROPHONE AND SPEAKERS
The microphone must be positioned in front
of the center of your mouth as detailed
Speaker A
above.
Attach the speakers to the Velcro inside
your helmet, opposite your ears (short
Speaker B
speaker cord for left ear & long speaker cord
for right ear). Use the supplied Velcro pads if
needed.
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:

Lead the speaker cord [B] alongside the
rim of the padding to the right side
and then back to the left side, near
speaker [A]. Then place the speaker

to Standby mode.
• Not all Bluetooth mobile phones can broadcast Bluetooth Stereo music
(A2DP), even if the phone has an MP3 player function. Consult your mobile
phone’s User Manual for more information.
• With some mobile phones, you may need to tap the Mobile Button
to connect the G4 to the phone after pairing is complete. The G4 will
automatically connect to the last phone it is paired with.
