LG8271/LG9271
5.0 REGULATORY APPROVAL
This section outlines the regulatory information for the
LG8271/LG9271 module for the following countries:
• Europe (LG8271)
• United States (LG9271)
5.1 Europe
The LG8271 module has been tested in accordance
with the ETSI EN 300 220-2 V2.4.1 (2012-05) RF
standard and been determined to be compliant.
Table 5-1 lists the summary report documenting the
compliance.
Additional R&TTE testing is required for Health and
Safety (Article (3.1(a)) and Electromagnetic
Compatibility (EMC) (Article 3.1(b)).
The R&TTE Compliance Association provides
guidance on modular devices in document Technical
Guidance Note 01 available at
http://www.rtteca.com/html/download_area.htm.
5.1.1 LABELING AND USER
INFORMATION REQUIREMENTS
The label on the final product which contains the
LG8271 module must follow CE marking requirements.
The “R&TTE Compliance Association Technical
Guidance Note 01” provides guidance on final product
CE marking.
5.1.2 EXTERNAL ANTENNA
REQUIREMENTS
From R&TTE Compliance Association document
Technical Guidance Note 01:
Provided the integrator installing an assessed radio
module with an integral or specific antenna and
installed in conformance with the radio module
manufacturer's installation instructions requires no
further evaluation under Article 3.2 of the R&TTE
Directive and does not require further involvement of
an R&TTE Directive Notified Body for the final product.
[Section 2.2.4]
5.1.3 HELPFUL WEB SITES
A document that can be used as a starting point in
understanding the use of Short Range Devices (SRD)
in Europe is the European Radio Communications
Committee (ERC) Recommendation 70-03 E, which
can be downloaded from the European Radio
Communications Office (ERO) at: http://www.ero.dk/.

Note: To maintain conformance to the testing
listed in Table 5-1: European Compliance
Testing, the module shall be installed in
accordance with the installation instruc-
tions in this data sheet and shall not be
modified.
When integrating a radio module into a
completed product the integrator
becomes the manufacturer of the final
product and is therefore responsible for
demonstrating compliance of the final
product with the essential requirements of
the R&TTE Directive.
