1.0 INTRODUCTION
The Telematics Control Unit (TCU) described herein is a vehicle mounted Telematics control
unit designed and manufactured by Continental for exlusive use by a premium automotive
OEM. The product name has been designated by the customer as RAMSES (Router And
Mobile SErviceS). The TCU contains an embedded LTE wireless communication module
and interacts with remote call/data centers to provide valuable services to the vehicle
customer.
1.1 PURPOSE AND SCOPE
This conditions document is to provide installation instruction to OEM to insure safe use of
the device.
1.2 TCU FUNCTIONALITY
The RAMSES TCU provides LTE advanced connectivity to the vehicle and interfaces to the
vehicle head unit as well as the Ethernet buss. The TCU is designed to
• intiate automatic emergency calls if an automatic emergency call trigger is received;
• allow initiation of a Manual Emergency Call by a car occupant;
• allow manual initiation of Roadside Assistance or Inforamtion Calls by a car
occupant;
• establish Data Packet Connection with telematics service;
• establish Data Packet Connection to support the internet connection of Head Units
equipped with WiFi (Head Unit is not Continental’s product).

2.3 AUDIO SUBSYSTEM
The Ramses TCU audio system will provides a hands-free user interface for emergency
Telematics calling within a vehicular environment. The user interface is realized through the
seamless connection between the Ramses TCU module and the vehicle.
At a glance Ramses audio system shall provide the following interfaces.
• Microphone front end input with switchable bias
• Amplified speaker driver via class D amplifier
• Speaker load diagnostics and protection via PA I2C
• Support for digital audio IO via HDBaseT
• Hands-free processing and prompt playback realized by the SOC

4.0 VEHICLE INSTALLATION GUIDELINES
Normal operating conditions are between -40oC to +80oC.
The sheet metal cover is designed to be a heat sink. A gap between the heat sink and the
mounting surface is recommended to facilitate heat transfer out of the module. Exceptions
can be made if the module is mounted to a surface that can help facilitate heat transfer such
as a large aluminum body panel.
WARNING: When the temperature of the device is above 70oC, the metal cover will be hot.
DO NOT TOUCH.
The device does not have sealed connectors. It is designed to meet Class I water intrusion
conditions (no drip test required), so it should not be placed in area that can get wet.
Continental recommends that the automotive OEM uses the mating harness supplier’s
recommendations for the keep out zone around the connectors to ensure proper mating of
each connector.
Changes or modifications to this system by other than a facility authorized by Continental
could void authorization to use this equipment.
5.0 REGULATORY COMPLIANCE NOTES

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.
7
- 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.
INDUSTRY OF CANADA:
This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to
the following two conditions:
(1) This device may not cause interference; and

compliance with the U.S. and CANADA RF Exposure Regulations”. This text, or similar,
must be included into the car manual.
Antenna Information:
Only the same or equivalent-type antennas as shown below have been evaluated and may be
used with this module. Other un-equivalent-type antennas may require additional
authorization for operation. The equivalent-type means the same antenna type that results in
similar in-band and out-of-band radiation patterns.
For incorporation in Vehicle platform (the distance from the antenna to the user according to
OEM installation requirements):

Antenna Placement:
This device is authorized for installation in qualified vehicles that can provide enough
minimum separation distance. To ensure RF exposure compliance the antenna(s) used with
this module must be installed in vehicles to provide a minimum separation distance, in all
operating modes and orientations of the vehicles. The separation distance is measured from
the antenna and the passengers in all directions for potential exposure conditions. This
module must not be co-located with any other RF modules or transmitters. Additional SAR
evaluation and FCC equipment approval would be required if other RF modules or
transmitters are co-located with this module. The required minimum separation distance for
the antenna placement is 10.25 mm.
