The scala rider PowerSet provides you with an impressive Bike-to-

Bike Intercom range by simply flipping 

up the antenna. The flip-up antenna 

allows you to maximize the intercom 

range with other bikers at up to 1 mile / 

1.6 km (subject to terrain). The antenna is 

also useful when riding in dense urban 

environments that may affect the 

transmission quality. You may keep the 

flip-up antenna open when not using 

the intercom, even though there is no particular need to do so.

The scala rider G4 PowerSet package contains two factory paired 

G4 headsets. To set up additional Intercom Bluetooth connections, 

you must first pair your G4 headset with the other headsets. 
Pairing is a one time process. Once completed, the headsets will 

remain paired and automatically recognize each other whenever they 

are within range.

section 9.11 below
Your headset has two Intercom channels available for headset-

to-headset connections. Therefore, your G4 can communicate 

simultaneously with up to two other headsets. If one of these 

other headsets is connected to yet another G4 headset, then all 

four participants can enter into a 4-way conference mode (see 

section 9.10c below).
9.2 BACKWARDS COMPATIBILITY
Your scala rider G4 can also conduct Intercom communications with 

earlier scala rider models in different configurations and you can 

always change your preferences.

There are four other scala rider models available that your G4 can 

connect to, and each of these connections comes with specific char-

acteristics and / or limitations.
In terms of range, Intercom communications between your G4 and 

another scala rider unit is limited to the distance of the lesser-range 

device. For example, connecting your G4 with a Q2 unit will enable 

intercom distances of up to 500 m / 540 yards, which is the maximum 

rated distance the Q2 can achieve.
In the section below you can find out how to pair your G4 with 

other scala rider models, such as the “Q2™”, “Solo™ “, “FM™ “, or a 

Driver unit of the “TeamSet™”. In addition, your headsets are also 

fully compatible with the Schuberth SRC-System™. For details, visit 

www.cardosystems.com/src.

9.3 BEFORE STARTING THE INTERCOM
Your scala rider G4 headset has two buttons designated for quick 

connection to two other headsets. These other headsets are referred 

to as CHANNEL “A” and CHANNEL “B”. In the following sections 

you will also learn how to add a third participant and conduct an 

intercom conference mode.
