3 Device Installation and User Manual
The WT50RW02 module is a proprietary product designed and manufactured by Continental Automotive
Systems, Inc. for integration into telematics control units manufactured by Continental Automotive
Systems, Inc. for automotive OEMs.
i. The module is limited to installation ONLY in an integrated device manufactured by Continental
Automotive Systems, Inc.
ii. During manufacturing process of the integrated device, the module is soldered onto the pcb of the
integrated device.
iii. The integrated device must provide RF connectors to external antennas or RF traces to connect the
WT50RW02 modules to antennas inside the integrated device. The typical reference design for the
RF trace layout, including pcb stack-up and trace length is described in Section 6 of this document.
iv. Automotive OEM is responsible for ensuring that the end-user has no manual instructions to
remove or install module.
v. The module is limited to installation in mobile applications, according to Part 2.1091(b).
vi. No other operation configurations are allowed.
vii. Changes or modifications to this system by other than a facility authorized by Continental could
void authorization to use this equipment.
viii. The module must be installed to provide a separation distance of at least 20 cm from all persons.
ix. The integrator is responsible for fulfilling FCC and IC requirements for the integrated device.
If Continental chooses to re-use modular approval, then the TCU shall be clearly labeled with an external
label containing the integrated modem’s FCC ID. For example, the label can include text “Contains device
with FCC ID: LHJ-WT50RW02 and IC: 2807E-WT50RW02”.
