4.2 SPOKEN STATUS ANNOUNCEMENTS
Your scala rider G4 headset offers various audio status messages 

sent through your speakers. Among others, it will announce your con-

nection state, e.g. whether you are in mobile phone or on intercom 

mode, it will confirm changes of such modes and more. By default 

the feature is ON, and can be disabled as outlined below.

The Voice menu can be set at any one of the available language op-

tions. In the future, more languages will be available for downloading 

from our website (see section 4.4 for Firmware Upgrade).
Entering the Voice Menu: Press and hold the CHANNEL “A” button 

and CHANNEL “B” button simultaneously for 3 seconds while the 

headset is on standby. Once entering the system, follow the voice 

instructions in English or choose your preferred language.
Disable/Enable status announcements: Press and hold the 

Volume Down Button for 6 seconds.

The different audio sources connected to the G4 are prioritized as 

shown below, i.e. the higher priority source will always override and 

interrupt the lower one. 
For example, incoming mobile phone calls will interrupt ongoing 

Intercom calls, while incoming intercom calls will interrupt the audio 

from the built-in FM Radio etc.
