You can charge the SRL2 by connecting the supplied USB power &
data cable into a computer’s USB port or USB wall charger. You can
use any standard micro-USB cable to charge the SRL2. 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.

Note:

Any 3rd party USB charger can be used with Sena products if the charger
is approved by either the FCC, CE, IC or other locally approved agencies
that Sena accepts.

CAUTION

Please make sure to take off your SRL2-installed helmet while charging.

indicating the battery level.

4 ashes = High, 70~100%

3 ashes = Medium, 30~70%

2 ashes = Low, 0~30%

Note:

1. The battery performance may be reduced over time with usage.

2. Battery life may vary depending on conditions, environmental factors,
functions of the product in use, and devices used with it.

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.

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 high-toned double beeps 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.

17

English

SRL2

the SRL2 is ready to use. You will hear a voice prompt from the
SRL2 saying “Your headset is paired”.

6. If the pairing process is not completed within three minutes, the
SRL2 will return to stand-by mode.

18

4.2 Second Mobile Phone Pairing

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 Center Button for 12
seconds until you hear high-toned double beeps. You will hear a
voice prompt saying “Conguration menu”.

2. Within 2 seconds, double tap the (+) Button, then the LED turns to

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.

4.3 Bluetooth Stereo Device Pairing

1. If a Bluetooth stereo device is integrated with the mobile phone
such as smartphones, you don’t need to pair the SRL2 with it
separately. When the SRL2 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

Note:

1. If Bluetooth connection between the headset and a mobile phone is
disconnected, press the Center Button for 3 seconds to recover the
Bluetooth connection immediately.

2. If Bluetooth connection between the headset and a media player is
disconnected, press the Center Button for 1 second to recover the
Bluetooth connection and play.

17 ADDITIONAL INTERCOM SETTINGS

17.1 Audio Multitasking™ (Default: Enable)

You can enable or disable Audio Multitasking through the Sena Device
Manager or the Sena Smartphone App. 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
nished. If this feature is disabled, any incoming or outgoing intercom
will interrupt your audio channel.

17.2 Intercom-Audio Overlay Sensitivity (Default: 6)

You can adjust Intercom-audio overlay sensitivity through the Sena
Device Manager or the Sena Smartphone App. 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 10 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.

17.3 Audio Overlay Volume Management (Default: Disable)

You can enable or disable Audio Overlay Volume Management through
the Sena Device Manager or the Sena Smartphone App. 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.

17.4 HD Intercom (Default: Enable)

You can enable or disable HD Intercom through the Sena Device
Manager or the Sena Smartphone App. 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.

SRL2

17.5 Eight-Way Intercom (Default: Disable)

You can enable or disable Eight-way Intercom through the Sena
Device Manager or the Sena Smartphone App. Disabling the Eight­way Intercom optimizes the intercom performance for a small group
up to four participants. Enabling the Eight-way Intercom optimizes the
intercom performance for a larger group up to eight participants.

17.6 Advanced Noise Control™ (Default: Enable)

You can enable or disable Advanced Noise Control through the Sena
Device Manager or the Sena Smartphone App. 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.

Note:

If you use your SRL2 with the Bluetooth Audio Pack for GoPro, you can
enable or disable this feature only during Normal Voice Recording. This
feature is automatically disabled while in Ultra HD (UHD) Voice Recording
mode.

18 REMOTE CONTROL

You can remotely control the SRL2 via Bluetooth using the Remote
Control (sold separately). This eliminates the need to take off your
hand for button operations. Your SRL2 and the Remote Control must
be paired together before use.
