Initiate Intercom calls from a G4
There are two ways to start an Intercom call with your paired headsets 
while the G4 is in Standby mode:
VOICE CONNECT:
Start talking loudly
Once you start talking loudly, an Intercom 
call will be established with both paired 
devices, CHANNEL “A” and CHANNEL “B” (if 
both are available). 
CHANNEL BUTTON 
CONNECT:
Single tap the CHANNEL 
“A” or "B" Button to add or 
remove the chosen channel 
from an Intercom call.
10. CLICK-TO-LINK
Click-to-Link is the spontaneous “social” nature of your scala rider G4. 
This unique feature will enable you to instantly initiate one-to-one 
intercom calls with other G4 users in the near vicinity without going 
through a pairing process in advance. Think of it as a private bike-to-
bike channel that you can set up on-the-y with other scala rider G4 
users that you spot next to a trac light or along the road. 
The Click-to-Link feature can of course be disabled at any time, blocking 
any attempt by other G4 users to establish a spontaneous link.
USING CLICKTOLINK
Disable/Enable Click-to-Link: The feature can be turned on or o 
via the Settings Customization Menu (see Section 4.2). By default, 
this feature is DISABLED.
AUDIO SOURCES AND PRIORITIES
The dierent 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 and GPS navigation 
instructions will interrupt ongoing Click-to-Link calls, while incoming 
Click-to-Link calls will interrupt the audio from the built-in FM Radio etc.
Click-to-Link established calls and Intercom calls have the same 
priority: If one is in use, the other is unable to interrupt. Therefore, a 
Click-to-Link request cannot interrupt an Intercom call in progress, and 
vice-versa.
Higher Priority
1. Mobile Phone audio or GPS instructions (device 
specic) 
2. Intercom / Click-to-Link (same priority level)
3. A2DP audio source
4. FM Radio (built-in) 
5. Auxiliary Line-In Port (for corded connection 
e.g. MP3 players).
Lower Priority
IC (Intercom) Request Tone: If you are on a Click-to-Link call and 
Rider A or Rider B try to connect to you for an IC Call, you will hear an 
IC Request Tone while the other party will hear a rejection beep.
If your Click-to-Link connection is dropped for any reason and other 
G4 users are nearby, new Click-to-Link connections may link up with 
users other than your initial connection.
