Before using the N-Com device for the first time, recharge the battery completely for
at least 10 hours. To obtain best performances from the battery, it is recommended
to completely recharge the battery the first few times. Afterwards, you can recharge
the battery for shorter periods. Whenever possible, it is best to recharge the battery
completely.
To recharge the N-Com B4 system, connecto the USB cable to the battery charger or
to a USB plug.
14.1. Battery discharged signal
When turned on, the system signals when the battery is running down by switching to
the “Reserve” mode.
When the battery charging power falls below 1 hour of operation, the buttons “▲” and
“-” start to flash in order to indicate that the system is in “Reserve” mode. Three
consecutive beeps also signal the reserve mode.
When the battery operates in “Reserve”, the system automatically turns itself off in
case no button is pressed for 30 minutes. The shutting off is signaled by a series of
beeps in the helmet. This function makes it possible to always have a small reserve of
energy to use it again in case you forget to turn off your helmet.
