2.2 Installing the modem

To install the modem, plug the device on a DC power supply (for automotive applications, connect the device on
the permanent « + » and insert the SIM card in the holder).

Make sure that an antenna is connected.

In order to extract or to insert the Micro SIM card, it is necessary to press the SIM holder ejector
with a sharp element (a pen for example).

If this sequence is not respected, the SIM holder could be damaged.

INSTALLATION/START-UP

2.3 Electrical characteristics

2.3.1 Switching the GSM modem on/off

The device is permanently powered (when connected to the power supply).

2.3.2 Voltage range

Voltage range : 5 to 32V DC
GND : 0V

2.3.3 Overvoltage/undervoltage

Correct operation of the Wavecom WMOD2B modem in communication mode is not guaranteed if input voltage
fall below 5V. The modem is protected against voltage over 32V.
When input voltages exceed 32V, the supply voltage is disconnected in order to protect the electronic components
from an overvoltage.

TWO CASES ARE POSSIBLE:

- IF THE OVERVOLTAGE IS CONTINUOUS, THE PROTECTION IS GUARANTEED BY THE FUSE.

- IN THE CASE OF TRANSIENT PEAKS, THE MODEM GUARANTEES ITS OWN PROTECTION.
