LTE 4G NAD Module
The LTE 4G is a CAT 4 Rel. 14 NAD is a family of proprietary embedded modules designed by Continental
Automotive Systems, Inc. The modules will be integrated into Data Connectivity Modules (DCM-TCUs) or
USB hosts (HUs) designed and produced by Continental or by a 3rd party for use by automotive OEMs.
DCM-TCUs will be installed into vehicles during the OEM’s factory assembly process and will not be
accessible without use of special tools. Primary use-cases are data-centric with data and voice
connections to Telematics Service Providers (TSP).

5 Storage and Handling
5.1 Moisture Sensitivity Level (MSL)
All NAD modules are moisture sensitive and should be kept in their sealed moisture resistant bags until
ready for assembly onto the DCM-TCU via the soldering process. Any parts that are not used
immediately should be properly resealed in the same moisture resistant bag using appropriate
equipment or placed into a dry box until they are needed again. The moisture sensitivity level (MSL)
shown below is the amount of time the NAD modules may be exposed before this action must be taken.
If the allowed MSL time elapses, the NAD modules must be baked per standard protocol to remove
moisture.
Moisture Sensitivity Level: MSL Level 3 (1 Week)
