GM47/48 Design Guidelines
BA/SEM/MSC 02:0006 Rev PA1 22
6 Type Approval
The system integrator has to get CE marking for the integrated solution
with the GSM module in Europe (GM47) and the FCC approval in the
US (GM48). The system integrator only has to show compliance with
the essential requirements of the module by the integration of it into the
application.
If the external elements are designed according to the guidelines of this
document the testing would be the following:
• Integration with GM47
• EMC in all modes of operation
• Safety
• Integration with the GM48
• FCC approvals of all applicable parts
Sony Ericsson recommends that all these tests are performed by the
customer in an accredited test house. After that, all documentation
together with the test reports and certificates of the application should
be sent to Sony Ericsson in order to register the application to the
accessories list for the approval of the module, this will aid the
approval of the application world wide.
6.1 Documentation required
The system integrator is required to produce a document which will be
submitted to the test house containing the following information.
• Summary of the application
• Hardware description
• Block diagram with an explanation
• Schematics
• PCB/Component layout
• Bill of materials
This documentation will also be required for Sony Ericsson to add the
application to the list of approved accessories for the module in
addition to the test reports and certificates obtained from the test house.
6.2 Power supply
It is essential the application power supply is designed to comply with
the specification in section 3. This will be sufficient to pass type
approval, no RF testing will be required if it meets these specifications.
