8.2.3 APPROVED EXTERNAL ANTENNA
TYPES
Transmitter Antenna (from Section 7.1.2 RSS-Gen,
Issue 3, December 2010):
The RN4020 module can only be sold or operated with
antennas with which it was approved. Transmitter may
be approved with multiple antenna types. An antenna
type comprises antennas having similar in-band and
out-of-band radiation patterns. Testing shall be per-
formed using the highest gain antenna of each combi-
nation of transmitter and antenna type for which
approval is being sought, with the transmitter output
power set at the maximum level. Any antenna of the
same type having equal or lesser gain as an antenna
that had been successfully tested with the transmitter,
will also be considered approved with the transmitter,
and may be used and marketed with the transmitter.
When a measurement at the antenna connector is
used to determine RF output power, the effective gain
of the device's antenna shall be stated, based on mea-
surement or on data from the antenna manufacturer.
For transmitters of output power greater than 10 milli-
watts, the total antenna gain shall be added to the mea-
sured RF output power to demonstrate compliance to
the specified radiated power limits.

The RN4020 module is an R&TTE Directive assessed
radio module that is CE marked and has been manu-
factured and tested with the intention of being inte-
grated into a final product.
The RN4020 module has been tested to R&TTE Direc-
tive 1999/5/EC Essential Requirements for Health and
Safety (Article (3.1(a)), Electromagnetic Compatibility
(EMC) (Article 3.1(b)), and Radio (Article 3.2) and are
summarized in Table 3-1: European Compliance Test-
ing. A Notified Body Opinion has also been issued. All
test reports are available on the RN4020 product web
page at http://www.microchip.com.
The R&TTE Compliance Association provides guid-
ance on modular devices in document Technical
Guidance Note 01 available at

8.3.1 LABELING AND USER
INFORMATION REQUIREMENTS
The label on the final product which contains the
RN4020 module must follow CE marking requirements.
The “R&TTE Compliance Association Technical Guid-
ance Note 01” provides guidance on final product CE
marking.
8.3.2 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 mod-
ule manufacturer’s installation instructions
requires no further evaluation under Article 3.2
of the R&TTE Directive and does not require fur-
ther involvement of an R&TTE Directive Notified
Body for the final product. [Section 2.2.4]

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 Commu-
nications Office (ERO) at: http://www.ero.dk/.

Note: To maintain conformance to the testing
listed in Ta bl e 8 -1 , the module shall be
installed in accordance with the installa-
tion instructions 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.
