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.
