The tracking current is tested in following conditions:
 For Cold Start, 10 minutes after First Fix.
 For Hot Start, 15 seconds after First Fix.
5.5. Electrostatic Discharge
Although the module is generally protected against Electrostatic Discharge (ESD), ESD protection
precautions 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 the module are shown in the following table.
