EC-R&TTE Certificated
If the ETRX2 module is incorporated into an OEM product, the OEM product manufacturer must
ensure compliance of the final product to the European Harmonised EMC, and low voltage/safety
standards. A Declaration of Conformity must be issued for each of these standards and kept on
file as described in the R&TTE Directive. The final product must not exceed the specified power
ratings, antenna specifications and installation requirements as specified in this ETRX2 user
manual. If any of these specifications are exceeded in the final product then a submission must be
made to a notified body for compliance testing to all of the required standards.
The ‘CE’ marking must be applied to a visible location on any OEM product. For more information

full
responsibility for learning and meeting the required guidelines for each country in their distribution
market.
2.2 ETRX2HR only
The ETRX2HR module has not been submitted for FCC or CE with an external antenna.
2.3 Declarations of Conformity
Telegesis (UK) Ltd has issued Declarations of Conformity for the ETRX2 ZigBee® RF Modules,
which cover Radio Emissions, EMC and Safety. These DOC’s are available from our website or

2.4 IEEE 802.15.4
IEEE 802.15.4 is a standard for low data rate, wireless networks (typical over the air data rates of
250 kbps @2.4GHz) which focuses on low cost, low duty cycle, long primary battery life
applications as well as mains-powered applications. It is the basis for the open ZigBee® Protocol.
2.5 The ZigBee® Protocol
The ZigBee® Protocol is a set of standards for wireless connectivity for use between any devices
over short to medium distances. The specification was originally ratified in December 2004, paving
the way for companies to start making low-power networks a reality.
ZigBee® uses an IEEE 802.15.4 radio specification running on the 2.4GHz band, plus three
additional layers for networking, security and applications. What makes the specification unique is
its use of a mesh network architecture which, in bucket chain style, passes data from one node to
the next until it lands at its destination. The network is self-healing and adapts its routing as link
quality changes or nodes move. Furthermore, nodes can be defined as End Devices which do not
act as routers, but can therefore be put into a low-power sleep state.
The enhanced version of the ZigBee® standard (or ZigBee® 2006) was released in December
2006, adding new features and improvements to the only global wireless communication standard
enabling the development of easily deployable low-cost, low-power, monitoring and control
products for homes, commercial buildings and industrial plant monitoring. In 2007 the ZigBee
Alliance produced the very latest edition of the standard including the PRO featureset which offers
advantages over earlier versions, including
