About GE MDS
Almost two decades ago, GE MDS began building radios for business-critical applications. Since
then, we ve installed nearly 100,000,000 radios in over 110 countries. To succeed, we overcame
impassable terrain, brutal operating conditions and disparate, complex network configurations. We
also became experts in wireless communication standards and system applications worldwide. The
result of our efforts is that today, thousands of utilities around the world rely on GE MDS-based
wireless networks to manage their most critical assets.
The majority of GE MDS radios deployed since 1985 are still installed and performing within our
customers’ wireless networks. That s because we design and manufacture our products in-house,
according to ISO 9001 which allows us to control and meet stringent global quality standards.
Thanks to our durable products and comprehensive solutions, GE MDS is the wireless leader in
industrial automation including oil and gas production and transportation, water/wastewater
treatment, supply and transportation, electric transmission and distribution and many other utility
applications. GE MDS is also at the forefront of wireless communications for private and public
infrastructure and online transaction processing. Now is an exciting time for GE MDS and our cus-
tomers as we look forward to further demonstrating our abilities in new and emerging markets.
As your wireless needs change you can continue to expect more from GE MDS. We’ll always put
the performance of your network above all. Visit us at www.GEmds.com for more information.
OPERATIONAL & SAFETY NOTICES
UL/CSA Notice
This product is available for use in Class 1, Division 2, Groups A, B, C & D Hazardous Locations. Such locations are
defined in Article 500 of the National Fire Protection Association (NFPA) publication
NFPA 70
, otherwise known as
the National Electrical Code.
The transceiver has been recognized for use in these hazardous locations by two independent agencies Underwriters
Laboratories (UL) and the Canadian Standards Association (CSA). The UL certification for the transceiver is as a Rec-
ognized Component for use in these hazardous locations, in accordance with UL Standard 1604. The CSA Certifica-
tion is in accordance with CSA STD C22.2 No. 213-M1987.
UL/CSA Conditions of Approval: The transceiver is not acceptable as a stand-alone unit for use in the hazardous
locations described above. It must either be mounted within another piece of equipment which is certified for
hazardous locations, or installed within guidelines, or conditions of approval, as set forth by the approving agencies.
These conditions of approval are as follows:
The transceiver must be mounted within a separate enclosure which is suitable for the intended application.
The antenna feedline, DC power cable and interface cable must be routed through conduit in accordance with the
National Electrical Code.
Installation, operation and maintenance of the transceiver should be in accordance with the transceiver’s installation
manual, and the National Electrical Code.
(UL/CSA Notice continued on next page...)
Tampering or replacement with non-factory components may adversely affect the safe use of the transceiver in haz-
ardous locations, and may void the approval.
Professional installation required. The radio equipment described in this guide emits radio
frequency energy. Although the power level is low, the concentrated energy from a direc-
tional antenna may pose a health hazard. Do not allow people to come closer than 23 cm
(9 inches) to the antenna when the transmitter is operating in indoor or outdoor environ-
ments. More information on RF exposure is on the Internet at
