Switching The Microphone - Sena 20S User Manual

3.3 Switching the Microphone

If you want to use a different microphone instead of the static boom
microphone, please refer to the following steps.
1. Remove the back plate of the clamp unit by loosening the two
screws with the enclosed allen wrench.
2. If you look into the back side of the clamp, the left port is for
speakers and the right port is for microphone.
3. Two extra microphones are provided, a wired boom microphone
and a wired microphone. Connect the one you need according to
your helmet type.
4. Reattach the back plate to cover the microphone and the speaker
port.
5. Follow Steps in section 3.1, "Helmet Installation" to complete the
clamp installation.
3.3.1 Wired Boom Microphone
When installing the included wired boom microphone, place the velcro
end of the boom microphone between the internal helmet cheek pad and
the internal wall of the helmet shell. The boom microphone should be
mounted so it is facing close to your mouth when you wear the helmet.
3.3.2 Wired Microphone
In case of the wired microphone, attach the enclosed velcro pad
for the wired microphone to the inside of the chin guard for full-face
helmets. Place the wired microphone on the velcro pad and connect it
to the connector of the clamp unit.
