Continental FE3RW0051 LTE 4G CAT4 NAD Module User Manual

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)
