3 INSTALLING THE 20S ON YOUR HELMET
3.1 Helmet Installation
2. Depending on the size and shape of your helmet, you may need
to change the thickness of the rubber pad between the clamp
plates. You can find two extra rubber pads in the box. To increase
the overall thickness, attach the thinner one to the original rubber
pad or replace the original rubber pad with the thicker one.
To securely install the 20S on the helmet, please follow this procedure.
1. Loosen the two screws on the back plate of the clamp unit using
the enclosed allen wrench. Insert the back plate of the clamp unit
between the internal padding and external shell of the helmet, and
tighten the two screws. Please make sure that the microphone is
located properly close to your mouth when you wear the helmet.
3. Please adjust the direction of the microphone so that the fin side
of the microphone is facing outward; away from your lips. You can
easily recognize it by touching the fin with your fingers.

4. Place the helmet speakers along with the hook and loop fasteners,
centered to your ear, in the ear pockets of the helmet. If the helmet
has deep ear pockets, you can use the speaker pads to place the
speakers closer to your ears.
To enhance the audio quality, you can make use of the foam speaker covers.
Cover each speaker with the foam and attach the hook fastener at the
back of the speaker. Then place the speakers in the helmet as described
above. Foam covered speakers work most effectively when they are slightly
touching your ears (20S Basic Kit only).

5. Hook on the adapter to the clamp unit then screw in the glued
external adapter to the clamp unit.
6. Locate a proper surface on the helmet to attach the unit then
clean the helmet surface location with a moistened towel and
allow to dry thoroughly.
12
Note:
Sena recommends the clamp unit over the glued surface mounting
adapter. Even though the glued surface mounting adapter is provided for
convenience, Sena does not assume any responsibility for use of it. Users
may have to use the glued adapter at their own risk and responsibility.
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.
20S
English
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. Lock the microphone to the clamp by turning the lock clockwise.
5. Reattach the back plate to cover the microphone and the speaker
port.
6. Follow steps in section 3.1, “Helmet Installation” to complete the
clamp installation.
3.3.2 Wired Microphone
In case of the wired microphone, attach the enclosed hook and loop
fastener for the wired microphone to the inside of the chin guard for
full-face helmets. Place the wired microphone on the hook and loop
fastener and connect it to the connector of the clamp unit.
3.3.1 Wired Boom Microphone
When installing the included wired boom microphone, place the hook
and loop fastener end of the boom microphone between the internal
helmet cheek pad and the internal wall of the helmet shell. The boom

you wear the helmet.
13
20S
3.4 Earbuds
If you want to wear your own earbuds, connect the earbuds to the
earbud port on the left side of the clamp. You can connect your
earbuds to the clamp while having the speakers connected to the
clamp. The sound of the earbuds will be active while the sound of the
outer speakers becomes inactive.
4 GETTING STARTED
4.1 Charging
You can charge the 20S by connecting the supplied USB power &amp; data
cable into a computer USB port or USB wall charger. You can use any
standard micro-USB cable to charge the 20S. The LED turns red while
the headset is charging and turns blue when it is fully charged. It takes
about 2.5 hours to be completely charged.
4.2 Low Battery Warning
3.5 External Antenna
To extend the intercom distance, you may unfold the external antenna
from the main unit. Push the antenna towards the helmet slightly and
it will flip upwards. The antenna works most effectively when facing
towards the sky.
14
When the battery is low, the blinking blue LED in stand-by mode turns
to red and you will hear three, mid-toned beeps and a voice prompt
saying “Low Battery”.
4.3 Checking the Battery Level
You can check the battery level in two different ways when the headset
is powering on.
20S
4 flashes = High, 70~100%
3 flashes = Medium, 30~70%
2 flashes = Low, 0~30%
4.3.2 Voice Prompt Indicator
When you power on the headset, keep pressing the Jog Dial and the
Phone Button simultaneously for about 3 seconds until you hear three,
high toned beeps. Then you will hear voice prompt indicating the battery
level. However, if you release the buttons as soon as the headset turns on,
you will not hear the voice prompt for the battery level indication.
4.4 Powering On and Off
Press the Jog Dial and the Phone Button at the same time to power the
headset either on or off. When powering on the headset, press the Jog
Dial and the Phone button at the same time until the blue LED appears
while hearing the ascending beeps. When powering off the headset,
press the Jog Dial and the Phone Button at the same time until the
red LED appears briefly and the headset turns off completely while
hearing descending beeps.
4.5 Volume Adjustment
You can easily adjust the volume by rotating the Jog Dial. You will
hear a beep when the volume reaches maximum or minimum level.
The volume is set and maintained independently at different levels
for each audio source even when you turn off and on the headset.
For example, once you set the volume for mobile phone handsfree,
it will not change even if you adjust the volume for your Bluetooth
MP3 music. So you can always maintain the preferred optimum volume
level for each audio source.
4.6 Software
4.6.1 Sena Device Manager
The Device Manager allows you to upgrade the firmware and configure
the device settings directly from your PC. Using this software, you can
assign speed dial presets, FM radio frequency presets and more. It is
available to download for both Windows and Mac. For more information
on downloading the Device Manager, please visit www.sena.com.
4.6.2 Sena Smartphone App
The Sena Smartphone App allows you to configure the device
settings, create groups of intercom friends, and view the quick start
guide. Simply pair your phone with your 20S headset, run the Sena
Smartphone App and you can configure its settings directly from your
smartphone. You can download the Sena Smartphone App for Android
or iPhone from www.sena.com/headset-app/.

English
4.3.1 LED Indicator
When the headset is powering on, the red LED flashes rapidly
indicating the battery level.
20S
5 PAIRING THE 20S WITH BLUETOOTH DEVICES
Before using the 20S Bluetooth headset with any of Bluetooth devices
for the first time, you will need to pair them together. It can be paired
with Bluetooth mobile phones, Bluetooth stereo devices such as MP3
players, or motorcycle specific Bluetooth GPS navigation, and with
other Sena Bluetooth headsets. This pairing operation is only required
once for each Bluetooth device. The headset remains paired with the
devices and automatically reconnects to them when they are within
range. You will hear a high tone single beep and a voice prompt when
the headset connects to the paired device automatically: “Phone
connected” to a mobile phone, “Media connected” to a Bluetooth
stereo device.
5.1 Mobile Phone Pairing
5.1.1 General Mobile Phone Pairing
1. Turn on the 20S and press the Phone Button for 5 seconds until
the LED flashes red and blue alternately and you hear multiple
beeps. You will hear a voice prompt saying “Phone pairing”.
2. Search for Bluetooth devices on your mobile phone. Select the
Sena 20S in the list of the devices detected on the mobile phone.
16
3. Enter 0000 for the PIN. Some mobile phones may not ask for the
PIN.
4. The mobile phone confirms that pairing has completed and the
20S is ready to use. You will hear a voice prompt from the 20S
saying “Your headset is paired”.
5. If the pairing process is not completed within three minutes, the
20S will return to stand-by mode.
5.1.2 NFC Mobile Phone Pairing
You can quickly pair your mobile phone using NFC (Near Field
Communication) technology with your NFC-enabled mobile phone.
1. Make sure that your mobile phone has the NFC function turned on
and that the phone screen is active.
2. Turn on the 20S and remove the main unit from the clamp unit.
3. Place your mobile phone over the back side of the 20S so that the
NFC detection area of each device touches each other.
4. Follow the pairing instructions that appear on your phone. If a
passcode is required, enter “0000”.

20S
5.2 Second Mobile Phone Pairing
Note:
English
Typical Bluetooth headsets can connect with only one Bluetooth
device, but a second mobile phone pairing allows the headset to
connect with another Bluetooth device such as a second mobile
phone, an MP3 Player, or the Sena SR10, the Bluetooth adapter.
1. To pair the second mobile phone, press the Jog Dial for 6 seconds
until the red LED is rapidly flashing and you hear multiple beeps.
2. Within 2 seconds, tap the Phone Button again, then the LED turns
to blue flashing and the beeps turn to high toned double beeps.
You will hear a voice prompt saying “Second mobile phone
pairing”.
3. Search for Bluetooth devices on your mobile phone. Select the
Sena 20S in the list of the devices detected on the mobile phone.
4. Enter 0000 for the PIN. Some mobile phones may not ask for the
PIN.
5. The mobile phone confirms that pairing has completed and the
20S is ready to use. You will hear a voice prompt from the 20S
saying “Your headset is paired”.
6. If you want to pair the Sena SR10, Bluetooth adapter, please refer
to the section 5.5, “Pairing with the Sena SR10, Bluetooth Twoway Radio Adapter”.
If you have two audio (A2DP) devices connected to your headset then the
audio from one device will interrupt the audio from the other device. For
example, if you are playing music from the primary mobile phone, then it
can be interrupted by playing music from the secondary mobile phone and
vice versa.
5.3 Bluetooth Stereo Device Pairing
1. If the Bluetooth stereo device is integrated with the mobile phone
such as smartphones, you don’t need to pair the 20S with it
separately. When the 20S is paired with the mobile phone, it is
also paired as a stereo music device.
2. If you have a stand alone Bluetooth stereo device, follow the
pairing procedure separately. The procedure is the same as the
procedure in section 5.1, “Mobile Phone Pairing”.
Note:
1. If Bluetooth connection between the headset and a mobile phone is
disconnected, tap the Phone Button to recover the Bluetooth connection
immediately.
2. If Bluetooth connection between the headset and a media player is
disconnected, press the Jog Dial for 1 second to recover the Bluetooth
connection and play.
17
20S
5.4 Bluetooth GPS Navigation Pairing
5.4.1 GPS Pairing

4. Enter 0000 for the PIN.
5. The GPS confirms that pairing has completed and the 20S is
ready to use. You will hear a voice prompt from the 20S saying
“Your headset is paired”.
6. If the pairing process is not completed within three minutes, the
20S will return to stand-by mode.
Note:
If you pair your GPS device via GPS Pairing, its instructions will not interrupt
your intercom conversations, but overlay with them.

GPS Pairing as Mobile Phone
Note:
English
5.4.2 GPS Pairing as Mobile Phone
If a GPS is not only used for turn-by-turn voice instructions but also is
your preferred Bluetooth stereo music source, you can pair the GPS
to the 20S by following the simple procedures in “5.1 Mobile Phone
Pairing”. However, since some GPS systems support mobile phone
bridging over Bluetooth, you can pair the mobile phone to the GPS to
use your mobile phone. When you do this, the 20S thinks the GPS is a
mobile phone so you can no longer pair your mobile phone to the 20S
directly. Please refer to the user’s guide of your GPS for details.
You have to use a motorcycle specific GPS which transmits turn-by-turn
voice instruction to the headset by Bluetooth. Most automotive GPS systems
don’t have this feature.
5.5 Pairing with the Sena SR10, Bluetooth Two-way
Radio Adapter
The Sena SR10 is a Bluetooth two-way radio adapter for group
communication, and uses HFP as do most motorcycle specific GPS
navigation systems. If you pair the 20S with a SR10 by second mobile
phone pairing, the 20S is able to have two HFP devices at the same
time: a mobile phone and the Sena SR10.
1. Turn on the headset and press the Jog Dial for 6 seconds until the
red LED is rapidly flashing and you hear multiple beeps.
2. Within 2 seconds, tap the Phone Button again, then the LED turns
to blue flashing and the beeps turn to high tone double beeps.
You will hear a voice prompt saying “Second mobile phone
pairing”.
3. Turn on the SR10 and follow the SR10’s “Bluetooth Headset
Pairing” procedure to complete the process. Please refer to the
SR10 user's guide for details.
4. When the pairing is completed, you will hear a voice prompt
saying “Your headset is paired”.
19
20S
5. If the pairing process is not completed within three minutes, the
20S will return to stand-by mode.
The incoming audio from the two-way radio via SR10 is heard in
the background while having an intercom conversation or a mobile
phone call. You can listen to music, answer a mobile call, have an
intercom conversation and use a two-way radio via the SR10 for group
communication as shown in the figure below. A GPS system or a
radar detector which has a headphone jack or audio line-out could
be connected to the SR10 by a wire. The GPS voice instruction or the
radar detector alarm is also heard in the background via the SR10
while having an intercom conversation or a phone call. Please refer to
the SR10 User's Guide for details.
