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.
Thank you for these details. I was about to ask you regarding this behavior.
I have one question if you may.
As far as I understand from the above explanation if I receive the Low Battery notification (which is too low to hear it if you are using the FM Radio while Recording, but let's suppose I hear it) if I put my Sena 10C to charge using the CHARGER 5V (B-TYPE) I MUST STOP the FM Radio if I want to use the Recording function. If I do that I can Start the Recording again and it will go on until I stop it manually (and no Low Battery notification will be received).
Could you please confirm if I understood correctly?
Thank you in advance,
I have been using the camera for a few weeks with no issues. But the past few days I get the "Battery Low, Camera Off" message when the 10C is fully charged (four red flashes when I turn it on). This happens a few seconds after I turn on video recording. I am using Firmware 1.04. I can take still photos but it will not record video.
