Cardo G4 Manuel D’Utilisation

The G4 offers VOX technology for safe and hands-free operation of 

some key functions.

For incoming calls, just pronounce loudly any word (e.g. “hello”). To 

reject an incoming call, you need only to remain silent for about 15 

seconds. To reject an intercom call remain silent for 30 seconds.

While on standby press and hold the Volume Up and Volume Down 

Buttons simultaneously for three seconds until you hear a beep. The 

default status is Voice Connect enabled.

You can delete all of your paired devices at any time as follows:

1. With the scala rider G4 headset turned ON, press and hold the 

Mobile Button  for at least six seconds until the Red and Blue Lights 

begin rapidly alternating.

2. Press and hold the Volume Up Button for three seconds.
3. The Red and Blue Lights will flash five times simultaneously and 

then the headset will turn off, confirming that Reset was success-

fully completed.

To pair your G4 to other scala rider models, please refer to section 

9.10 c below.

b. Busy Status (When using a G4 headset)

When attempting an Intercom call with a headset that is already on 

a Phone/GPS/Intercom call, you will hear two beeps indicating the 

other headset is busy.
c. Automatic Reconnection of the Intercom
If your headsets get disconnected because they exceed the intercom 

range, they will automatically try to reconnect when they are again 

within range.

You can also manually reconnect by pressing the corresponding Channel 

Button (“A” for the factory-paired PowerSet units). For manual reconnec-

tion, only one user should press the Channel Button. 
d. Conference Mode Limitations
Whenever you enter the Intercom Conference mode among three 

or even four participants (including yourself), the participants who 

maintain simultaneously two active connections will not be able to 

receive mobile phone calls or GPS messages as long as the confer-

ence call is in progress (see details in sections 9.10 b and 9.10 c)

First, make sure your microphone is located properly in front of the 

center of your mouth.

The scala riderG4 is designed for use in loud environments. 

Therefore, you should test the Intercom functionality only in a noisy 

environment, such as next to an idling motorcycle and not indoors. 

Please also verify that the headsets were paired together properly by 

following the instructions in the relevant Setup sections.
