IMPORTANT:
The scala rider G4 is a water-resistant device, designed for use under moderate rain or snow
conditions. However, the headset is not rated waterproof and should not be used under severe
weather conditions. The cover lid protecting the Charging Jack should be kept tightly closed at
all times to prevent moisture from entering the device.
3. CHARGING THE HEADSET
Make sure that your headset is fully charged for at least four hours before initial use.
Insert the USB cable to the wall charger (see image below) and insert the other end of the cable to
the headset’s Charging Jack. While charging, the Red Light turns on. When charging is complete, the
Red Light will turn off.
Your wall charger and USB Dock Connector cable serve two purposes:
1 Charging your headset from any A/C wall socket or from any USB port of your computer
(
charging time takes longer)

6. GETTING STARTED
a. MOUNTING THE HEADSET ON THE HELMET
The Helmet clamp that includes your microphone and speakers must first be mounted on the helmet.
Once mounted, the headset unit can be attached or detached from the clamp at any time.
There are two methods that can be used in order to attach the clamp onto the helmet:
•Standard Method: Recommended for most helmet types.

PAGE 8 / 28
•Glue Plate Method: Recommended for helmets to which the standard method cannot be
applied, using the Glue Plate included in the box.
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 the special version helmet clamp with corded microphone please refer
to the section” ATTACHING THE CORDED MICROPHONE CLAMP ON A FULL-
FACED HELMET”
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. This option
has been successfully used for a range of high end helmets.
Caution: This process can be done only once!
NOTE: While we have no reason to believe that the gluing option might negatively affect any helmet, Cardo does not assume any responsibility to that
affect, irrespective of its nature and circumstances. The Glue Plate is offered 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.
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 as described in # 4 below).
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 firmly 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.
If you have purchased the special version helmet clamp with corded microphone please refer
to the section” ATTACHING THE CORDED MICROPHONE CLAMP ON A FULL-
FACED HELMET”
ATTACHING THE CORDED MICROPHONE CLAMP ON A FULL-FACED HELMET
The instructions below are for installing a helmet clamp with a corded microphone for users who have
purchased the special helmet clamp version for Full-Faced helmets. Once the clamp is attached to
your helmet, in either standard or Glue method as described previously in the user guide, please
follow the instructions below in order to install the corded microphone.
a. Use the pre-moistened towelette to clean the exact spot on the internal padding of the helmet,
opposite your mouth, where the microphone will be placed.
Pic showing both methods

PAGE 9 / 28
b. Peel the foil cover from the adhesive Velcro pad and place the Velcro pad on the chosen location
opposite your mouth.
c. Attach the microphone on the Velcro, as in photo.
d. Tighten the screws of the Clamp.
b. POSITIONING THE MICROPHONE & SPEAKERS
The microphone is to be positioned in front of the center of you mouth as detailed previously. Only
once you attach the helmet clamp with microphone on your helmet, you may proceed with attaching
the speakers.
Attach the speakers to the Velcro inside your helmet, opposite your ears (short speaker cord for left
ear & long speaker cord for right ear), or use the supplied Velcro pads.
If the internal padding of your helmet has cavities opposite your ears, i.e. on those spots where you
need to place the speakers, you may want to consider some improvement ideas to achieve better
audio quality. Please visit
www.cardosystems.com/files/audio.pdf
c. ATTACHING AND REMOVING THE HEADSET FROM THE HELMET CLAMP
ATTACHING:
Slide the headset sideways (i.e. in a horizontal way) along the sliding panel until a clicking sound
indicates that the headset is locked in place.
REMOVING:
Your headset can be removed for charging or for storage by sliding the headset sideways. Ideally,
when pushing the headset unit with your thumb you should embrace it between thumb and index
finger in order to avoid it from falling off.
ATTACHING:
Slide the headset downwards along the sliding panel until a clicking sound indicates that the headset is locked in place.
REMOVING:
Press here to remove
Your headset can be removed for charging and storage by pressing your finger gently against the tab and sliding the headset up with
the other hand.
We recommend that you remove the headset from the helmet when not in use
d. USING THE FLIP-UP ANTENNA
The flip-up antenna allows you to achieve the maximum intercom range between bikers. Simply
press gently against the protruding tab (at the tip of the antenna) towards the direction of the helmet.
The internal spring will then cause the antenna to flip up (see image above).
To close the antenna, just bend it backwards into its horizontal state until it’s locked in place.
As the
flip-up antenna sole purpose is to increase intercom range between bikers, there is no need to open it for when using
your mobile phone, FM Radio or MP3 Player. No harm can be done to the headsets functionality by leaving the antenna

PAGE 10 / 28
open even when there is no use of Intercom. However, leaving the antenna open may result in increasing it’s
vulnerability,
in case your helmet falls on the ground or if it is exposed to any accidental impact.
