Audio Boost (Default: Disable)
Enabling Audio Boost increases the overall maximum volume. Disabling Audio Boost reduces the overall maximum volume, but delivers more balanced sound.

Smart Volume Control (Default: Disable)
Smart Volume Control automatically changes the level of the speaker volume based on the level of the environmental noise. When it is disabled, volume is controlled manually. You can enable the level adjustment by setting the sensitivity to low, medium, or high. Smart Volume Control responds to smaller environmental noises as the sensitivity level becomes higher.

VOX Phone (Default: Enable)
If this feature is enabled, you can answer incoming calls by voice.

VOX phone is temporarily disabled if you are connected to intercom. If this feature is disabled, you have to tap the Center Button to answer an incoming call.

VOX Intercom (Default: Disable)
If this feature is enabled, you can initiate an intercom conversation with the last connected intercom friend by voice. When you want to start intercom, say a word such as “Hello” loudly or blow air into the microphone. If you start an intercom conversation by voice, the intercom terminates automatically when you and your intercom friend remain silent for 20 seconds. However, if you manually start an intercom conversation by tapping the Center Button, you have to terminate the intercom conversation manually.
However, if you start intercom by voice and end it manually by tapping the Center Button, you will not be able to start intercom by voice temporarily.

After rebooting the headset, you can start intercom by voice again.

HD Voice (Default: Disable)
HD Voice allows you to communicate in high-definition during phone calls. This feature increases the quality so that the audio will be crisp and clear during phone call conversations. If this feature is enabled, incoming phone calls will interrupt intercom conversations and audio from the SR10 will not be heard during intercom conversations. Three-Way Conference Phone Call with Intercom Participant will not be available if HD Voice is enabled.

Note:
Refer to the manufacturer of your Bluetooth device that will be connected to the headset to see if it supports HD Voice.

HD Intercom (Default: Enable)
HD Intercom enhances the two-way intercom audio from normal quality to HD quality. HD Intercom will become temporarily disabled when you enter into a multi-way intercom. If this feature is disabled, the two-way intercom audio will change to normal quality.

Note:

1. The intercom distance of HD Intercom is relatively shorter than that of normal intercom.
2. HD intercom is active only when Audio Overlay is disabled.

Intercom VOX Sensitivity (Default: 3)
VOX sensitivity can be adjusted depending on your riding environment. Level 5 is the highest sensitivity setting and 1 is the lowest.

Voice Prompts (Default: Enable)
You can disable voice prompts by software configuration settings, but the following voice prompts are always on.

• Headset configuration settings menu, battery level indicator, speed dial

Sidetone (Default: Disable)
Sidetone is audible feedback of your own voice. It helps you to naturally speak at the correct level according to varying helmet noise conditions. If this feature is enabled, you can hear what you are speaking during an intercom conversation or a phone call.

Advanced Noise Control™ (Default: Enable)
When Advanced Noise Control is enabled, the background noise is reduced during an intercom conversation. When it is disabled, the background noise is mixed with your voice during intercom.

Audio Overlay™ (Default: Disable)
Audio Overlay allows you to hear the audio from two features simultaneously. When Audio Overlay is enabled, phone calls, GPS instructions, and intercom conversations can be overlaid with audio from the music or GPS app instructions from a smartphone in the background with reduced volume. Increasing or decreasing the volume of the audio in the foreground will also increase or decrease the volume of the overlaid audio in the background. The volume of the foreground audio can be adjusted using the headset. How much background audio that is heard can be adjusted using the Sena Motorcycles App. HD Intercom and Audio Source Priority become disabled temporarily when Audio Overlay is enabled.
