Note: GPRS Class 12 is the default setting. The module can be configured from GPRS Class 1
to Class 12 by “AT+QGPCLASS”. Setting to lower GPRS class would make it easier to design
the power supply for the module.
5.5. Electro-static discharge
Although the GSM engine is generally protected against Electrostatic Discharge (ESD),
precautions about ESD protection should still be emphasized. Proper ESD handling and packaging
procedures must be applied throughout the processing, handling and operation of any applications
using the module.
The measured ESD values of module are shown as the following table:
