13. BATTERY

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.

13.1. Battery discharged signal

While the system is operating, it indicates when the battery has about 1 hour of charge left. The

system LEDs stat to flash to indicate the “RESERVE” status. This warning is repeated every 10 minutes.

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.

on the system during the first few minutes of the charging, as the voltage may drop below the
