5.4. ESD Protection

LC79D GNSS module is an ESD sensitive device. ESD protection precautions should be emphasized.
Proper ESD handling and packaging procedures must be applied throughout processing, handling and
operation of any application that incorporates the module.
Please note that the following measures are beneficial to ESD protection when LC79D module is handled.
