Powering On
Press and hold the (+) Button and the (-) Button at the same time for 1
second to power on. The blue LED turns on and you will hear ascending
beeps and “Hello”.
Powering Off
Press the (+) Button and the (-) Button at the same time. The red LED
turns on for about 2 seconds until it turns off completely and you will hear
“Goodbye” and descending beeps.
Charging the 3S
You can charge the 3S by connecting the supplied USB power & data
cable into a computer USB port or USB wall charger. You can use any
standard micro-USB cable to charge the 3S. The LED turns red while
charging, and turns blue when the headset is fully charged. It takes
about 2.5 hours to fully charge.

Checking Battery Level
You can check the battery level in two different ways when the headset
is powering on.
LED Indicator
When the headset is powering on, the red LED ashes rapidly indicating
the battery level.
LED Status
4 ashes High, 70~100%
3 ashes Medium, 30~70%
2 ashes Low, 0~30%
Voice Prompt Indicator
When you power on the headset, keep pressing and holding the (+)
Button and (-) Button simultaneously for about 3 seconds until you hear
three high tone beeps. Then you will hear a 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.
Note:
1. The USB power & data cable is also used for firmware upgrade of the 3S.
2. The USB wall charger is not included in the package. Any 3rd party USB
charger can be used with Sena products if the charger is approved by either
FCC, CE, IC, or other locally approved agencies that Sena accepts. Please
contact Sena regarding locally approved agencies Sena accepts.

Low Battery Warning
When the battery is low, the blinking blue LED in stand-by mode turns to
red and you will hear mid-tone triple beeps and a voice prompt saying
“Low battery”.
Adjusting the Volume Level
You can easily adjust the volume by pressing the (+) Button or the (-)
Button. 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 when you
hear Bluetooth MP3 music. So you can always maintain the preferred
optimum volume level for each audio source.
Function Priority
The 3S operates in the following order of priority:
(Highest) Mobile Phone
Intercom
(Lowest) Bluetooth Stereo Music
A lower priority function is always interrupted by a higher priority
function. For example, stereo music is interrupted by an intercom call,
and intercom conversation is interrupted by an incoming mobile phone
call.
Fault Reset
When the 3S is not working properly or is in faulty status for any reason,
you may reset by pushing the pin-hole reset button on the left speaker
unit. Insert a paper clip into the reset pin-hole and press and hold the
reset button for a second with light pressure. The 3S will be switched
off after which time, you have to turn the system back on and try again.
However, this will not restore the headset to factory default settings.
