17. BATTERY AND RECHARGE
17.1. Low battery signal
During its operation, the system alerts the user with a voice message when the battery is low. From
the first message, the system has a 1-hour autonomy. Warning is given every 10 minute.
17.2. Checking the Battery Level
LED Indicator
When the system is powering on, their blue LED flashes rapidly indicating the battery level.
4 flashes = High, 70 ~ 100%
3 flashes = Medium, 30 ~ 70%
2 flashes = Low, 0 ~ 30%
Vocal Indicator
Starting from the system turned off, press at the same time the “n” and “” keys for about 3 seconds
until you hear three, high toned beeps. Then you will hear a voice prompt indicating the battery level.
However, if you release the keys as soon as the system turns on, you will not hear a voice prompt for
the battery level indication.
17.3. Charging the system
• To charge the system, connect the system to a charger or USB
plug using the USB-C cable supplied.
The charge will take place as follows:
When the B602 system is connected to the battery charger, the blue LED starts to flash
quickly. When the battery is charged, the blue LED becomes steady.
When the B602 system is connected to the battery charger, the blue LED starts to flash
quickly. When the battery is charged, the blue LED goes back to its standard flashing.
Note: In case you don’t plan to use the N-Com system for a long time, you need to fully recharge the
device before storing it away.
Note: In case the device is not used for a long time, carry out a complete recharging cycle of the
device at least once every 6 months to avoid possible damage to the battery.
Note: In case the N-Com system is left for more than 6 months without ever being recharged, the
device may not switch on; in this case, recharge the N-Com system for at least 24 hours (even if the
blue signalling LED is not flashing), then try to switch on the device again.
