MESH INTERCOM

7.1 What is Mesh Intercom?
Mesh Intercom™ is a dynamic communication system created by Sena that provides instant and effortless bike-to-bike communication without a pre-grouping process. Mesh Intercom allows riders to connect and communicate with nearby users without the need to pair each headset together.
The working distance between each 50S in Mesh Intercom can be up to 2 km (1.2 miles) in open terrain. In open terrain, the Mesh can be extended up to 8 km (5 miles) between a minimum of six users. Within the same channel in Open Mesh™ or the same private group in Group Mesh™, six users can talk at the same time and enjoy the optimal quality for their conversation. Mesh Intercom

• Some GPS devices may not support this feature.
• The Audio Multitasking feature can be configured through the Intercom-Audio Overlay Sensitivity and the Audio Overlay Volume Management settings.

13.2.10 Intercom-Audio Overlay Sensitivity (Default: 3)
The music, FM radio and GPS volume will be lowered to play in the background if you talk over the intercom while the overlaid audio is playing. You can adjust the intercom sensitivity to activate this background audio mode. Level 1 has the lowest sensitivity and level 5 has the highest sensitivity.
Note: If your voice is not louder than the sensitivity of the selected level, the overlaid audio will not be lowered.
13.2.11 Audio Overlay Volume Management (Default: Disable)
The music, FM radio and GPS overlaid audio reduces in volume whenever there is an ongoing intercom conversation. If Audio Overlay  Volume Management is enabled, the volume level of the overlaid audio will not be reduced during an intercom conversation.
13.2.12 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:

• The intercom distance of HD Intercom is relatively shorter than that of normal intercom.
• HD Intercom will become disabled temporarily when Bluetooth Intercom Audio Multitasking is enabled.

13.2.13 HD Voice (Default: Enable)
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 Voice is active only when Bluetooth Intercom Audio Multitasking is disabled.

13.2.14 Smart Volume Control (Default: Disable)
Enabling Smart Volume Control automatically changes the level of the speaker volume based on the level of the environment noise. You can enable it by setting the sensitivity to low, medium or high.
13.2.15 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.
13.2.16 Voice Assistant (Default: Enable)
If Voice Assistant is enabled, you can wake up Siri or Google Assistant using a voice command, such as “Hey Siri” or “Hey Google”. If you do not want to wake up Siri or Google Assistant with your voice, disable this feature.
13.2.17 Voice Prompt (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, FM radio functions
13.2.18 RDS AF Setting (Default: Disable)
Radio Data System (RDS) Alternative Frequency (AF) Setting allows a receiver to re-tune to the second frequency location when the first signal becomes too weak. With RDS AF enabled on the receiver, a radio station with more than one frequency can be used.
13.2.19 FM Station Guide (Default: Enable)
When FM Station Guide is enabled, FM station frequencies are given by voice prompts as you select preset stations. When FM Station Guide is disabled, the voice prompts on FM station frequencies will not be given as you select preset stations.
13.2.20 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.
