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).
Hardware Version Notes
This document may contain details specific to only certain Hardware revisions of the device. When
detailing properties unique to one or more HW revisions, the specific revision will be identified,

1.4 NAD Accessibility Requirement during development and certification
HS-USB and UART: Product teams must make sure to provide access to the NAD communication ports to
be used during development and certification testing. The following functionality must be avaialble after
the NAD is integrated:

Internal
 Access to the NADs HS-USB interface, including AT command, Diagnostics and NMEA ports.
 Ability to conduct basic call processing and data throughout measurements.
 NAD UART for communication using Linux console.
RF Ports: If on-board antennas are used by the product, provisions must be made to support conducted
RF measurements on all antenna interfaces: LTE Primary, Diversity and GNSS.
SIM Interface: Electrical performance of the SIM interface is always evaluated during certification
testing of the final product. Product teams must insure that the SIM interface can be accessed for
testing without degrading its integrity.

2 Regulatory Compliance Notes
2.1 Regulatory compliance notes
2.1.1 FCC:
This device complies with Part 15, Part 22(H), Part 24(E) Part 27 and Part 96 of the FCC Rules. The FCC ID
for this device is LHJ-FE3NA0031. Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause
undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
- Consult the dealer or an experienced radio/TV technician for help.
2.1.2 Industry of Canada:
