Operational Safety Notices
RF Exposure The radio equipment described in this guide emits radio frequency
energy. Although the power level is low, the concentrated energy from
a directional antenna may pose a health hazard. All antennas used with
this transmitter, whether indoor or outdoor mounted, must be installed
to provide a separation distance of at least 22 cm from all persons, and
must not be co-located or operating in conjunction with any other
MDS 05-3301A01, Rev. C

antenna or transmitter. In mobile applications (vehicle mounted) the
above separation distance must be maintained at all times. More information on RF exposure is available on the Internet at
www.fcc.gov/oct/info/documents/bulletins.
This manual is intended to guide a professional installer to install,
operate and perform basic system maintenance on the described radio.

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 three independent agencies —Underwriters Laboratories (UL), Factory Mutual Research Corporation (FMRC) and the Canadian Standards
Association (CSA). The UL certification for the transceiver is as a RecMDS 05-3301A01, Rev. C
MDS 9810 Installation and Operation Guide

ognized Component for use in these hazardous locations, in accordance
with UL Standard 1604. The FMRC Approval is in accordance with
FMRC Standard 3611. The CSA Certification is in accordance with
CSA STD C22.2 No. 213-M1987.
FM/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:
1. The transceiver must be mounted within a separate enclosure which
is suitable for the intended application.
2. The antenna feedline, DC power cable and interface cable must be
routed through conduit in accordance with the National Electrical
Code.
3. Installation, operation and maintenance of the transceiver should be
in accordance with the transceiver's installation manual, and the
National Electrical Code.
4. Tampering or replacement with non-factory components may
adversely affect the safe use of the transceiver in hazardous locations, and may void the approval.
5. When installed in a Class I, Div. 2, Groups A, B, C or D hazardous
location, observe the following:
WARNING —EXPLOSION HAZARD— Do not disconnect equipment unless power has been switched off or the area is know to be
non-hazardous.
Refer to Articles 500 through 502 of the National Electrical Code
(NFPA 70) for further information on hazardous locations and approved
Division 2 wiring methods.
FCC Notice, U.S.A.
