7. 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 SRL-EXT 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

SRL-EXT Motorcycle Mesh & Bluetooth® Communication System for Shoei Helmets

7 MESH INTERCOM

7.1.1 Open Mesh

Open Mesh is an open group intercom function. Users can freely

communicate with each other in the same Open Mesh channel and
select which channel (1-9) to use through the headset.

It can connect with a virtually unlimited number of users in each channel.

Open Mesh

Ch 1 Ch 2 Ch 3

Ch 4 Ch 5 Ch 6

Ch 7 Ch 8 Ch 9

7.1. 2 Group Mesh

Group Mesh is a closed group intercom function that allows users to

join, leave, or rejoin a group intercom conversation without pairing each
headset. Users can freely communicate with each other in the same
private group in Group Mesh.

For closed intercom conversations using Mesh Intercom, a Group
Mesh needs to be created by the users. When users create a private
group in Group Mesh by Mesh Grouping, the headset automatically
switches from Open Mesh to Group Mesh. Up to 24 users can all be
connected in each private group.

13.2.8 Bluetooth Intercom Audio Multitasking (Default: Disabled)

Audio Multitasking (Bluetooth Intercom Audio Multitasking and
Mesh Intercom Audio Multitasking) allows you to have an intercom

conversation while simultaneously listening to music, FM radio, or
GPS instructions. The overlaid audio is played in the background with
reduced volume whenever there is an intercom conversation and will
return to normal volume once the conversation is finished.

The Mesh Intercom Audio Multitasking feature is always on.

Note:

• For Bluetooth Intercom Audio Multitasking to work properly, you
need to power the headset off and on. Please restart the headset.

• Bluetooth Intercom Audio Multitasking will be activated during
two-way intercom conversations with a headset that also supports
this feature.

• 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.

13.2.9 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.

13.2.10 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.

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.

13.2.12 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.

You can disable Voice Prompts by software configuration settings, but

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.

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.
