If the battery option is present, prepare the modem for storage or transport phases in order to
limit high discharges of the battery. For that, see the 5.11 Turning OFF the modem
The following table describes the consequences of over-voltage or insufficient voltage on the modem.
Table 29 : Effects of power supply defect
Then:
Voltage falls below 6.5V
The functioning and the GSM communication are not
guaranteed
Voltage above 32V
(Punctual peaks)
The modem guarantees its own protection.
Voltage above 32V
(Continuous over-voltage)
The modem is protected by the fuse
(the modem is put in c.c. via a para surtensor internal
varistance).
The following tables show the consumption of the different functions of the modem.
The power supply consumptions may vary by 5% depending on the temperature range (-20
°C to +55 °C).

When the battery is completely discharged, 3 hours are necessary to obtain a new complete
charge.
