9. USING THE INTERCOM
Flip-up Antenna 
for extended range
9.1 INTRODUCTION
The scala rider G4 PowerSet provides 
you with an impressive Bike-to-Bike 
Intercom range by simply ipping up 
the antenna. The Flip-up antenna allows 
you to maximize 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 aect 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 units. To set up additional Intercom Bluetooth connections, you 
must rst pair your G4 units with other devices. In this manual such 
other devices will be referred to as CHANNEL “A” and CHANNEL “B” 
respectively.
Pairing is a one-time process. Once completed, the units will remain paired 
and automatically recognize each other whenever they are within range.
For details on Intercom use with other scala rider units, please refer to 
section 9.11 below
Each G4 has two Intercom channels available for multiple 
intercom connections. Therefore, one G4 can communicate 
simultaneously with up to two other G4s. If one of these other 
G4s is connected to yet another G4, then all four participants can 
enter into a 4-way conference mode (see section 9.10c below).
9.2 BACKWARDS COMPATIBILITY
The G4 can also conduct Intercom communications with earlier 
scala rider models in dierent congurations and you can always 
change your preferences.
There are other scala rider models available that the G4 can connect 
to, and each of these connections comes with specic characteristics 
and / or limitations.
In terms of range, Intercom communications between the G4 and 
another scala rider unit is limited to the distance of the lesser-range 
device. For example, connecting the G4 with a Q2 pro unit will enable 
intercom distances of up to 2,300 ft / 700 m, which is the maximum 
rated distance the Q2 pro can achieve.
In the section below you can find out how to pair the G4 
with other scala rider models. In addition, the G4 is also fully 
compatible with the Schuberth SRC-System™. For details, visit

9.3 BEFORE STARTING THE INTERCOM
The G4 has two buttons designated for quick connection to two other 
units. These other units 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.
