Class 10 is default set when the module works at data translation mode, the module can also work at class 8 set by
AT command.
5.5 Electro-Static Discharge
The GSM engine is not protected against Electrostatic Discharge (ESD) in general. Therefore, it is subject to ESD
handing precautions that typically apply to ESD sensitive components. Proper ESD handing and packaging
procedures must be applied throughout the processing, handing and operation of any application using a SIM900
module.
The measured values of SIM900 are shown as the following table:
