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 flashes rapidly indicating
the battery level.
LED Status
4 flashes High, 70~100%
3 flashes Medium, 30~70%
2 flashes 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
SX.COM.
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 SX.COM 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 SX.COM 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 SX.COM 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.

GPS Pairing as Mobile Phone
If 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
SX.COM by following the simple procedures in “Mobile Phone Pairing”.
When you do this, the SX.COM thinks the GPS is a mobile phone. But the
SX.COM can directly pair an additional mobile phone.
Note:
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.

available on the mobile phone. Refer to your mobile phone manual
for further instruction.
• To redial the last number, press and hold the (-) Button for 3
seconds in stand-by mode until you hear a high tone single beep.
You will hear a voice prompt saying “Last number redial”.
Note:
1.
If you are using multipoint mobile phone connection and you have an
incoming call from the second phone during the call of the first phone, then
you may still receive the call from second phone. In this case, the call from
the first phone is on waiting mode. If you end a call, then it will automatically
guide you to the first phone call.
2.
If you are using multipoint connection of mobile phone and GPS, you may not
listen to the GPS voice instruction during the phone call.
Stereo Music
You can listen to stereo music by Bluetooth wireless stereo. The Bluetooth
audio device must be paired with the SX.COM by following the
“Bluetooth
Stereo Device Pairing” instructions. The SX.COM
supports the Audio/
Video Remote Control Profile (AVRCP), so if your Bluetooth audio device
also supports the AVRCP, you can use the SX.COM to remotely control
music playback. So, you can not only adjust the volume but also use the
functions such as play, pause, track forward and track backward.
• To adjust the volume, press the (+) Button or the (-) Button.
• To play or pause music, press and hold the (+) Button for 1 second
until you hear a double beep.

The SX.COM supports firmware upgrade function. Please visit
Nexxpro,s.a. web site at www.nexx-helmets.com to check the latest
software downloads.
8. FIRMWARE UPGRADE BATTERY INFORMATION
The product has an internal, non-removable, rechargeable battery. Do
not attempt to remove the battery from the device as you may damage
the device. The battery can be charged and discharged hundreds of
times, but it will eventually wear out. Recharge the battery only with Sena
approved chargers designated for this device. Use of an unapproved
charger may present a risk of fire, explosion, leakage, or other hazard.
Always try to keep the battery between 15ºC and 25ºC (59ºF and 77ºF).
Extreme temperatures reduce the capacity and lifetime of the battery.
A device with a hot or cold battery may not work temporarily. Battery
performance is particularly limited in temperatures well below freezing.
Do not dispose of batteries in a fire as they may explode. Batteries may
also explode if damaged. Never use any charger that is damaged.
Operating times may differ depending on the devices used together,
features used, battery age and condition, temperatures to which battery
is exposed, and many other factors.
