4. BASIC FUNCTIONS
Note: 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.

off and you hear the voice announcement.
4.1. Volume adjustment
You can easily adjust the volume by tapping the “5” or the “6” key. You will hear a beep when the
volume reaches the maximum or minimum level.
The volume is independent for each sound source. Once it is set for a specific source (phone call,
radio, Mp3), it will be remain in memory even after the system is switched off.
However, if you adjust the volume during stand-by mode, it will affect volume levels of every audio
source.
4.2. Auto On / Off function
If the helmet does no move for more than 60 seconds, the B901 system goes into “deep sleep” mode.
The system is completely turned on as soon as movement is detected.
If the system is in “deep sleep” mode for more than 3 days, it turns off completely. To turn it back on,
the “
ON” key need to be pressed.
The “Auto On / Off” function is enabled by default on the device.
You can enable / disable the function from the Configuration Menu (Chapter 5).
