Installing the Main Unit

Using the Clamp Unit

  1. Loosen the two screws on the back plate of the clamp unit with the included allen wrench.
  2. Insert the back plate of the clamp unit between the internal padding and external shell of the left side of the helmet.
  3. Tighten the two screws until the clamp unit is fastened firmly to the helmet.
  4. Open the SD card cover and insert a microSD card (sold separately) into the card slot on the bottom of the main unit to use camera functions.
  5. Attach the main unit to the clamp unit until you hear a click. The main unit is now fastened to the clamp unit.

 

 If you cannot install the clamp unit on the helmet, you can use the glued surface mounting plate to attach the clamp unit to the surface of the helmet.

  1. Clean the area on the left side of the helmet where you will attach the glued surface mounting plate with a moistened towel and dry thoroughly.
  2. Peel off the cover of adhesive tape of the glued surface mounting plate and attach it to the helmet.
  3. Make sure that the glued surface mounting plate sticks on the helmet firmly. Maximum adhesion occurs after 24 hours.

CAUTION: Sena recommends using the clamp unit. The glued surface mounting plate is provided for convenience, but is not the recommended mounting method. Sena is not responsible for its use.

After using the camera on the 10C for a certain amount of time, you will hear a voice prompt say "Camera off. Battery low." but the User will still be able to continue using the other functions on the headset for about 2 hours. 

The battery on the 10C can be charged while it is in use to allow the User to power on the camera and keep recording videos or take photos. However, the camera on the 10C will not power on right away while charging the battery after hearing the "Camera off. Battery low" voice prompt. If the camera on the 10C does not power on right away then you will need to wait 1 minute in order for the battery to be charged long enough to turn on the camera and record videos or take photos. If you are communicating over the intercom or listening to music while charging the battery after hearing the "Camera off. Battery low" voice prompt then you will need to wait an additional 1 minute in order for the battery to be charged long enough to turn on the camera and record videos or take photos. 

The camera will automatically power off again within a few minutes if you are trying to charge the battery after hearing the "Camera off. Battery low." voice prompt while communicating over the intercom or listening to music because the battery hasn't been charged long enough since the headset is also providing battery power to those other functions. 

If you are charging the battery on the 10C while listening to music, communicating over the intercom and recording video using the camera then the charger will only provide enough battery power to the 10C to operate those functions and not enough power to also charge the battery at the same time.

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.

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 the Jog Dial and the Phone Button simultaneously for about 3 seconds until you hear high tone triple beeps. Then you will hear a voice prompt indicating the battery level is high, medium, or low.

Note:

If you pair the headset with an iPhone, you can check the headset’s battery next to the Bluetooth icon on the phone’s screen.

  1. Peel off each cover of the hook and loop fasteners for speakers to expose the adhesive surface. Then, attach the fasteners to the ear pockets inside the helmet.
  2. Attach the speakers to the hook and loop fasteners for speakers inside the helmet.

Note:

  1. The speaker with the shorter wire is for the left ear and the speaker with the longer one is for the right ear.
  2. If the helmet has deep ear pockets, you can use the speaker pads to bring the speakers closer to your ears.
  3. 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.

You can easily adjust the volume by rotating the Jog Dial. You will hear a beep when the volume reaches the maximum or minimum level. The volume is set and maintained independently at different levels for each audio source even when you reboot 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. However, if you adjust the volume during stand-by mode, it will affect volume levels of every audio source.

If you have a full face helmet, you can use the wired microphone.

  1. Attach the included hook and loop fastener for wired microphone to the inside of the helmet’s chin guard.
  2. Attach the wired microphone to the hook and loop fastener for wired microphone.
  3. Align the arrows on the microphone and speaker cables and insert the microphone cable into the speaker cable.
  4. Insert the speaker connector into the speaker port to connect it to the main unit.
  5. Close the cover of the speaker cable to lock the cable to the port. The speaker cable is now fixed to the main unit.

CAUTION: When you remove the headset, make sure that you first detach the speaker cable from the main unit. Then, it is safe to remove the main unit from the clamp unit.

You can charge the headset 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 headset. You can also charge the headset on the road using the cigarette charger. The LED turns red while the headset is charging and turns blue when it is fully charged. It takes about 3.5 hours to be completely charged.

  1. Peel off the cover of the hook and loop fastener for attachable boom microphone to expose the adhesive tape. Then, attach the fasteners on the inside surface of the left external shell.
  2. Attach the attachable boom microphone mounting plate to the hook and loop fastener
  3. Make sure that the microphone’s receiver is located near your mouth.
  4. Adjust the head of the microphone so that the tab is facing away from your mouth.
  5. Align the arrows on the microphone and speaker cables and insert the microphone cable into the speaker cable.
  6. Insert the speaker connector into the speaker port to connect it to the main unit.
  7. Close the cover of the speaker cable to lock the cable to the port. The speaker cable is now fixed to the main unit.
