This document can help you quickly understand module interface specifications, electrical and
mechanical details as well as other related information of SC20 module. Associated with application notes
and user guide, you can use SC20 module to design and set up mobile applications easily.
1.1. Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any cellular terminal or mobile incorporating SC20 module. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel and to incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for the
customer’s failure to comply with these precautions.
