Cardo G4 User Manual

Congratulations and thank you for choosing the scala rider G4 

PowerSet Bluetooth® Headset package for motorcycle helmets.

This manual will help you operate the headsets, but you should first 

familiarize yourself with the Bluetooth functionality of your mobile 

phone and/or GPS device before using the scala rider G4.

The PowerSet retail box contains two scala rider G4 headset units 

that are already factory paired. Amongst others, the headsets can be 

used as an Intercom at a range of up to one mile or 1.6 km (subject to 

terrain).

Your scala rider G4 PowerSet is a versatile communication and en-

tertainment system with a wide range of connectivity options. Each 

headset may be used as follows: 

1. as a Bluetooth headset for mobile phone communication (sup-

porting Bluetooth Headset and Handsfree* profiles at a range of 

10 m / 33 ft.)

2. as a Bluetooth stereo headset for wireless music streaming (sup-

porting the Bluetooth A2DP and AVRCP profiles, compatible with a 

variety of MP3 Players, adapters and other audio devices)

3. as a 3-Way Bike-to-Bike Intercom for conference calls with up to 

two other scala rider G4 or Q2 headsets (up to 1 mile / 1.6 km. 

range between two G4 headsets and in Full Duplex** mode)

4. as a 4-Way Intercom for conference calls between up to four G4 

headsets on two motorcycles (i.e. between two drivers and their 

passengers up to 1 mile / 1.6 km. range and in Full Duplex** mode)

5. as a Driver-to-Passenger Intercom (backwards compatible with 

earlier scala rider headsets)

6. as a Bluetooth headset for receiving GPS Navigation instructions 

and Streaming Audio from compatible Bluetooth devices

7. as a stereo headset for listening to the built-in FM Radio 

8. as a stereo headset for listening to cable-connected audio devices, 

(such as non-Bluetooth MP3 Players, iPods® and iPhones™)

according to ambient noise and driving speed. You can also control 

the volume level manually.
